Re: FEEDBACK and REVIEW for YAMATO 200 DC Inverter arc welder

Sorry if I'm bumping an old thread,. I'm a new member and I would like to first say thank you for creating this thread dedicated to Yamato arc welding machines! I'm just starting to dive in the welding hobby so I bought an inverter welder as my first machine.

I have a question concerning my recent purchase of a Yamato 200A Inverter,. I noticed that my unit seems a little different than the others posted in the thread. For example, the power switch is at the back, the ground clamp is steel/aluminum (silver color) instead of red(copper). The cables are also shorter (1 meter instead of 2 as stated by others).

Update: This is what my welder looks like: ( http://www.olx.ph/index.php/view+classifieds/id/45899163/Yamato+Portable+DC+Inverter+Welding+Machine+200A?referralKeywords=yamato+portable+welding+machine&event=Search+Ranking,Position,1-13,13 )

Beyond the placement and shorter cables, I'm disappointed to find out na 25%@ 200A lang ang indicated duty cycle (located in the bottom of the case instead at the back). Far cry from the 60-80% duty cycle of Yamato inverters posted before. Could this be a "fake" Yamato welder or just a "lower-tier" unit?

Also, the labels indicate a input frequency of 1-60Hz (instead of 50-60) and the included "Instruction Manual" has Jubo label instead of Yamato, however, one of their illustrated model looks exactly as my Yamato (including the rear placement of switch)- only that its labeled "Jubo".

I blame myself for buying the unit without inspecting the labeled specification, though I was in a hurry and did most research online, much like order and pickup nalang ika nga. It never came to me that there are more than one version of 200A Yamato inverters.

Any suggestions or comments is appreciated!! Thanks.

Hi Blisterpack,

Yes it seems there are quite a bit several manufacturers of the YAMATO brand coming from
China/Taiwan and are just riding under the original brand. If you will notice, the brand name now
are just stickers placed onto the metal casing and labeling don't carry the original logo.
So I suppose we do have a different supplier/importer, I am saying this coz we got our units direct
from the bodega of the importer and that we are assured of warranty and after sales service
which some of the members have already enjoyed.

Not saying that your unit is a fake one but I think what we have as Yamato welders are now the
generic kind so don't be too disappointed with your purchase.

What's important now is that its functioning properly the way it should,
it can weld using different welding electrodes, provided you follow the stated duty cycle.
For newbies dabbling or getting into welding, its a good entry level machine for being a
cheap priced DC machine.

CHEERS and keep safe

@ JAYL and Rosy

Thanks for the quick reply,. the item in the link is how my welder looks like, but I bought mine in Angeles City (inHandWorx if I remember correctly) and not from the online seller. My unit's Yamato brand name (located in either side of the unit) is embossed- not a sticker.

Here are some of the actual pictures:

Here's the specification label painted at the bottom of the case:

Seems like I only get full 10 minutes @ 100A (compared to 155A of others)

I replaced the stock stinger cable for a 20' line but the stock length is just 1m.

Also, I've tested the unit on the shop (used-up a whole stick) and the item is working, I'll still try to talk to the seller as you advised.

Thanks and more power!!!

Re: FEEDBACK and REVIEW for YAMATO 200 DC Inverter arc welder

To clarify, the OLD model that people know where the switch is at the front, is the old model for the MMA-200Handy.
Which has better specifications if you look at the written specs on the unit.

But the Newer model gets a downgrade in written specs but according to our other customers, they are
still the same in use and longevity, although we did not test to really know if the NEW one is still the same as the Last model..

We still have the 1st model unit at our shop and we show it to our customers to avoid confusion.
Maybe i showed it to you sir..

Maybe the other buyers of the new model that came from the PHM's other supplier can help us verify if the unit is the newer model.

Re: FEEDBACK and REVIEW for YAMATO 200 DC Inverter arc welder

According to our technicians, they preferred the newer model of the DC inverter in terms of durabilty and the duration of the machine before it overheats. They recommend this, because base on our record, the old models had a higher percentage of factory defects than the new ones.

As we have said before, we would look for another supplier for the DC Inverter who can provide us a better quality and a more durable machine. We want to provide our customers the satisfaction they deserve in terms of durability and quality of the machine.

Re: FEEDBACK and REVIEW for YAMATO 200 DC Inverter arc welder

Many thanks coolmaxheric and JosephS!!!

That cleared alot of my doubts about the unit,. well, as sir rosy mentioned, I'll still get a fantastic value out of the welder especially for the price I bought it. I'll try to use the unit more often for burn-in as a lot of you guys recommend, I still have six months of warranty to cover me incase the unit is defective.

Another question, about "burn-in", does the burn-in test only involves frequent "normal" use (like a mix of high-low amp runs) or do I really need to "push" as far as it can?

Also, assuming that its still fine and I'm out of the warranty period, can I add a digital ammeter to the unit similar to those found on more expensive models? I reckon that its almost impossible to "practically" integrate a digital meter on AC transformer units since they only register whenever the circuit is closed, but the IGBT inverter has circuits and other electronics stuff, is there some "terminal/tap" on those PCBs where I can get the readings?

Thanks and more power!!!

@ migueltyler,

Google mo na lang ang YAMATO DC Inverter for sale,Phil. Many new imports of new models are coming out now in the market. Only thing is that they seem to have lowered the duty cycles to 40% compared before of 60%. :dunno:
