Re: Yamato DC 200A Inveter Welder in Action

ito ang first welding ko ng yamato hehehe haponan ng mga manok ko 🙂

at ito naman po yong heavy duty extension wire ko LOL!!! kaya wag niyo tapon yong lumang CPU case may pakinabang din pala hehehe

Re: Yamato DC 200A Inveter Welder in Action

new here, already made my introductions just now.

anyway, i just bought this inverter tuesday of this week from gold peak. i also asked my friend from patts, an instructor there, a classmate of mine in my welding classes at tesda, he said that he could have gotten the same welding machine for much cheaper. so napamahal pa ako. sayang. lol.

anyway, nasa akin na ito and wala nakong magagawa. nabili ko na e. no choice na.

sabi sa akin, ito daw yung newer version. i also found out through the manual, yung duty cycle ng newer version is just 30% nalang instead of what i knew na 60%. natuwa ako nong tinest ko using a 6013 electrode na maganda ang buga at malinis. so here's my issue with the unit:

brought it with me this wednesday and tested it out during our welding classes coz we share among with us just one yamato buzz box (your typical ac type welding machine). medyo nasasayang oras namin kakaantay tapos iba pa sa amin hindi makagamit. tested it out and for some reason di ako makaweld ng maayos using 6011 rods (nihonweld). i know 6011 rods are harder to use but i've read online that 6011 rods were actually designed to run best on inverter type welding machines. so for the life of me, i can't get it to run right, kahit anong timpla ko sa amperage.

so my instructor told me to use the buzzbox and i pretty much welded with the 6011 perfectly. so i know it's not my technique or my electrodes or anything else. i was welding on a beveled 3/8 inch thick plate doing a root pass to join two beveled plates together and then 6013 electrodes for the hot pass / fill pass and a final capping with a 7018.

the dc inverter works perfectly fine on 6013. i didn't get to try out the 7018's yet since we ran out of time last wednesday. since this is a different unit than what you guys use, i was wondering if anyone else here has a similar unit to mine? the one with a 30% duty cycle. i mean the thing runs fine with 6013's even with 3 rods straight (i know i should rest it up for at least 5 to 7 minutes before the 3rd rod, but i'm testing my machine muna to see the limits).....

now this is making me think of getting an old school buzz box like a yamato 200a, the same as the ones we have at school since i have no problems welding with it.

i'm gonna be using my welding skills for welding motorcycle frames and modding them, making work tables for my projects etc.

i mean, with work tables and stuff, the inverter i got is perfectly fine for that, but i kinda think that i'm needing a buzz box for greater penetration for the frames i'm gonna be building, designing and modding coz i'll need to work with 6011 rods for that for peace of mind and better welds.

can anyone here help me out with settings and stuff with the inverter and using 6011's with it? coz i cannot root pass for the life of me with this thing.

the 6011 electrodes won't penetrate into the steel. it just wants to burn on top of the steel. if i stick it in further to melt the steel i'm welding onto, it just sticks and won't melt. but if i raise the amperage, the whole darn rod will just melt and burn up. (my setting for the 6011 is 110a-120a)....

is it just this version of the machine or is it the same for everyone here?

i almost wanna swap this out for an old school buzzbox now. even if it's ginormous and all, at least it does it's job (way better) and i can do what i need to do with it as well.

here's pix from goldpeak's post on sulit:

Re: Yamato DC 200A Inveter Welder in Action

franzb69,

I think your unit of YAMATO is very much different from the units we got from Industrialsupply143, that is if based on the external looks of the two units. With regards to the internals and performance, I cannot say anything but with what we have here and using, its a 60% duty cycle. I have been using mine for two years now without any issues, great with 6013, 7018, 7024 rods and even for stainless steel rods, I did not mention the 6011 rods since I don't really use this type of rods for my metal projects though I have done some practice welding with it from time to time using the Yamato DC 200 amp welder and Yamato AC 300 amp and my welds sucks for vertical up or down doing root pass and some other applications, really trying to learn its usage. I suppose coz I am only a self learner/self study guy in this skill and would still need more practice and most of us here are in the same situation.

Anyway according to coolmaxheric of Goldpeak Tools and Hardware is that what they are selling is from another supplier of this Yamato 200 amp DC Inverter IGBT welder. So I guess our units have different suppliers.

With regards to using the 6011 rods, I suppose you could do more practice with it using different ampere settings and find out what would suit you best. Plus the fact that you have gone to Tesda welding school with NC welding certifications, I suppose you can easily find out how to work better with the 6011 rods.

By the way with DC Inverter machines, once the the red warning lits up, better rest the machine for a few minutes, then you can start again. Always observe the duty cycle for maximum usage and output. DC machines are more sensitive than ordinary AC welder machines, though DC Inverters have lots of savings in terms of electric consumption and produces soft start. And if you want deeper penetrations on thicker metals, simply reverse the polarity.

CHEERS and enjoy welding !! :cheers::havefun::banana1:

Re: Yamato DC 200A Inveter Welder in Action

I still haven't recieced a reply from sir coolmaxheric of gold peak. I texted him and private messaged him on sulit. I asked if it was possible to swap the unit out with another brand. A 300a dc inverter model

Re: Yamato DC 200A Inveter Welder in Action

Why not send him a pm here, I would see his user's name here almost everyday.

What brand of DC welder do you have in mind just in case he says yes to your proposal. Just to remind you that any swapping with the increase in amperage and brand will entail you for additional payment.

Anyway, good luck ! 😉 :banana2:

Re: Yamato DC 200A Inveter Welder in Action

Paying extra for a better model and brand isn't a problem. So long as I can get better performance as well. Medyo hassle lang coz of the distance. Shoulda just bought a welding machine here in pque. I'll send him a pm here as well and hope to get a reply this time.

Nakakapag taka lang na nagtext ako at di nasagot. on his sulit account, he was online at least 5 hours ago and i messaged him earlier this afternoon, around 1pm. he would have been able to read my pm on sulit if he checked his messages.

I was thinking of getting the hitronic 200a DC inverter or even the 300a with arc force function(i saw it in coolmaxheric's inactive ads on sulit). i'm thinking i might be needing a welding machine with an adjustable arc force / dig function to get things right.

Thank you.

I'll do another test with 7018's tomorrow with higher amperage than what is suggested on the box. I've been using the 7018's today with the school's yamato buzzbox and it's been difficult but not impossible. With the 6011's on my inverter it just don't get me the same penetration with the old school coil type buzzbox. I'll do further testing tomorrow with 6011's and 7018's while waiting for sir coolmaxheroc's reply.

Re: Yamato DC 200A Inveter Welder in Action

Hey bro franzb69,

With regards to the brand you mentioned, the HiTronic DC Inverter, I suppose you will be satisfied with it. May I suggest you get the arc 250 amps or the 300 amps, these two variants can do heavy duty welding. Its made by SHENZHEN RILAND INDUSTRY CO. LTD., makers of Riland, Rilon and T&R DC Inverters

I can attest to this coz I have the HiTronic arc 300 amps which I purchased early part of December last year, also from Goldpeak Tools and Hardware, but its more than three times the price you paid for your new Yamato.

http://www.goldpeaktools.com.ph/products/welding-machine/hi-tronic.html

Prices stated at each unit are still subjected to a 20% discount.

Anyway here is the link of my review of the HiTronic 300 amp DC Inverter.

Hope this helps !! 😉

Re: Yamato DC 200A Inveter Welder in Action

I've read your posts which is why I was convinced with the hitronic DC inverter. I think I'll go with the one with the arc force adjuster. It'll make for easier usage of 7018's and 6011's. I find 7018's to be harder to use than 6011's.

Go all the way or go home. I always say.

Re: Yamato DC 200A Inveter Welder in Action

so here's coolmaxheric's reply:

For Swapping Unit sir..
Hindi po kami tumatanggap nyan sir eh, Puro Brand New lang po kasi tayo..
If you want your welder to have a check-up you can also bring it to EY or IndustrialSupply because they one of the nearest service center here in MANILA for YAMATO..

medyo disappointed ako since they refuse to let me replace the unit. guess i won't be buying from them anymore.

i'll just get another welding machine with better performance and might even end up getting a tig instead of an arc welder for my specific needs i'm gonna end up needing a tig anyway.

i'll keep this yamato for small quick and dirty jobs nalang and just keep using 6013's on it.

ah well.

thanks everyone for your help.

Re: Yamato DC 200A Inveter Welder in Action

Ended up getting a powercraft today from fine line industrial supply in sucat. Sister company to electro work on sulit. I was given a decent discount for what I got so I ended up buying it. This time I tested all the rods I had 6011, 6013, 7018 all nihonweld with 1/8 inch thickness. Also tested the tig as well. They had a big tank of argon they let me use and I was pretty happy with all of it. Bought the 200a version. I never had it this easy with either the 7018 or the 6011. It was a realization for me. I shouldn't have lowered my budget with all of it. I do realize that this is a China made welder but in terms of performance and the ease of access for me with fine line, I'm pretty darn happy.

Now I don't need an arc welder with arc force function coz this baby provides me with enough arc force for my needs.

Thank you again.

I will probably do a review for both the tig and the arc welder function for my new machine sometime after my welding classes in electron and getting an argon tank para isang review nalang.

Darn thing is way heavier. 8 kilos. No carrying strap like the yamato.

Re: Yamato DC 200A Inveter Welder in Action

Sorry bro regarding the swapping thing and it did not work out for you, perhaps if you have not used or tested the unit (Yamato) yet with different welding electrodes it may have been possible.

Anyway congrats for your new purchase of the Powercraft 200 DC Tig/Arc. Glad to know you are enjoying and seems satisfied with its performance and I suppose when you do a review of the unit ( please do ), You can start on a new thread for the unit.

Again congrats and cheers !! 😉

Re: Yamato DC 200A Inveter Welder in Action

Yes. Will do. I'll take pix of my work and practice stuff for review.

They let me test the unit sa gold peak before buying so using the unit during the first week shouldn't be much of an issue. They should have mentioned that they do not do returns or swapping of items. I wouldn't have bought it in the first place if they were gonna be like that.

I could have bought the unit for 3800 at a seller in sucat bought still bought it from them knowing that they had good service and even if they were a good distance away from me. Nahassle lang ako.

Bumili lang ako sa kanila kasi napadaan lang ako coz they were on the way to where I was going.

The p3800 for the yamato was a special price coz I knew people who knew the owners in the sucat place I mentioned.

Re: Yamato DC 200A Inveter Welder in Action

if i may add in.

DC welders provides more penetration.

btw, isa siguro yan sa handicap ng yamato 200A DC or any inverter at that range. kaya yung higher amps e may arc force funtion na.

for me as a DIY welder, enough na muna yung yamato inverter for projects around the house. kung bibili man ako uli (subject to availability of funds) e heavier duty models na siguro.

with regards sa swapping, in fairness na rin kay goldpeak, i think ganyan din siguro sasabihin ng ibang sellers. since pagdating sa 6013 ika ninyo e ok naman. we have the same problem with regards to 6011 rods (mahirap maistart at mamaintain yung arc). pero ok naman sa 6013, 7018 yung sakin.

buti pa nga kayo sir franz, 2 na inverter nyo.:p at least may backup na kayo para tuloy tuloy ang trabaho.

post nyo naman yung bago nyong inverter tsaka kung magkano for future reference.

Re: Yamato DC 200A Inveter Welder in Action

OK lang naman na no swapping basta nilinaw nila yun before the transaction. Para di nako mag isip ng kung and ano. I have been in retail for almost ten years. I always make everything clear with anyone I transact with all the fine print so they make an informed decision.

I'll post pix of my welders soon.

Re: Yamato DC 200A Inveter Welder in Action

so anyway.... i finally managed to get my welder replaced with a better machine.

i chose a yamato pa den but the one with the nice carrying case. this was facilitated by EY industrial sales and Miss Mimi of EY. She was wonderful to deal with, no questions, no ifs, no buts. If i was to get anything in QC that's hardware / tools I would much rather deal with EY. They're lightyears away from the kind of service that I was getting from my previous dealings with other sellers. Her people were very nice and courteous.

The difference in the Yamato that I got from Gold Peak and from EY is that the one from EY is a good bit heavier, the stinger was marginably better in quality, the grounding clamp was also a bit better. But since I already upgraded the stinger and the grounding clamp from my previous welder, I told the folks at EY that I'll swap my upgraded stinger and the ground clamp for the new one. So if they sell the machine I had could still be sold or used as a demo unit.

The new Yamato machine had different but similar switches and the terminal/port for the stinger was red, the previous one had both black. The power switch for the new machine also had an led that lit up when you switched it on. It had the same free welding mask, but mine did not have a handle for some reason. not that I would use it. I already have a powercraft auto darkening helmet and a regular flip type welding helmet.

I'll just keep this as my back up nalang in case the powercraft tig welder has a problem. I'll be mainly using the tig welder anyway for my needs.

Thank you again Ms. Mimi for all your help!
