Re: Stick Welder
How do you want them joined? Lap or butt?
Re: Stick Welder
based on my very quick google search, I'll be doing a combination of butt and corner joint.
i'll be cutting the ends of of 4 angle bars pieces into 45 degrees so that i can form a rectangle.
i actually explored with what i know as a butt joint but if i do this, the plywood that will be put on top of the rectangle will not be set onto two sides of the rectangle. there will a space between the plywood and the 2 parallel side of the angle bars.
im making a metal shelf so i guess i need the plywood completely set to the metal.
so back to my question, should the welds penetrate to the other side? should i weld in the underside or both sides considering the metal is thin?
Re: Stick Welder
No need to penetrate to the other side. Simple spot welds will do. Spot welds are much easier than making continuous welds. On the side opposite the weld you'll see discoloration of the metal.

well good. i am actually planning to just do some spot welds since i'm a newbie. tnx!
Re: Stick Welder
at the lowest possible amp setting (1 out 6) using the smallest welding rod i can find, i melted the angle bars.
what do you suggest i do? i'll try spot welding next time. spot welding needs some practice also.
i think i learned how to start the arc already. keeping the tip hot is a good suggestion.
another question is that how do i know the "rating" of my mask? i think the mask i'm using is a little bit light. i need a darker one.
Re: Stick Welder
Sorry bro I've no idea about the right mask rating.
You are probably not moving the electrode fast enough which is why your welds are penetrating to the other side. I would suggest you first practice spot welding before you try to do full welds. Most of the time only spot welds are needed, and in many cases you can use a lot of little spot welds to achieve the strength of a full weld. Watch out though for flux "pockets" (sorry I don't know the correct term). Usually, I only use full welds when I need to have it sealed (metal melting pot) or the application requires extra ordinary strength (trailer hitch). All my other projects are just spots.
By the way, congrats on enjoying yourself. Stay safe.
Re: Stick Welder
i got to try my welding skills on an actual home project yesterday.
starting the arc remains to be a problem to me. the rod kept sticking to the workpiece. however, once i am able to start it (with the rod tip kept glowing), the next weld is no problem.
the angle bars didn't melt this time (YEYYY!) and they were welded good enough although the weld beads are far from perfect.
might post some pics after i continue working next weekend.
Re: Stick Welder
Congratulations!
Re: Stick Welder
how's you project? can you also post pics of your yamato welder, pls pm the name of the shop where you bought it, I also want one, thanks.

my project is already finished except for top shelf of the rack. the plywood i bought was not enough so i left the topmost part open although i still was able to store some big stuff ("kalat").
i'll try to take some pictures of my project and the welder and post it here.
i forgot the name of the shop but it is located in T. Alonzo St. in Ongpin
Re: Stick Welder
I just came from panda hardware sa araneta ave and if I remember correctly meron mga nagtatanong about yung auto mask - meron sila 3500 - hartman if I'm not mistaken - it is soo sensitive that if you look up to the light it would darken right away - pretty cool
Re: Stick Welder
the cheapest stick welder i saw in handyman is a yamato 145a @ 9000, i cant wait to see what your portable yamato can do, i'll be wating for your post 4theboys, thanks
Re: Stick Welder
The mall hardware stores presently always price higher than the "regular" stores. Go to Binondo, or do as I do, find a nearby industrial supplier. The only thing I like about mall hardware stores is that they are more likely to have things display unlike the regular stores. So I window shop in the mall stores, as well as on the Internet, then I buy from my favorite industrial supply.
Here's another tip: a regular store might give you a "hobbyist's" discount.
Re: Stick Welder
ok here it is.
my Yamato 160amp portable arc welder
i bought this at this shop
it comes with this (a manual)
i was not able to take step by step pictures of my project so i'll show the finished product.
if you back read this thread, i used thin angle bars for this shelf or rack project. i think 3/16" thick. so i often used the lowest setting.
i used the welder to weld the corners of the platform and also to weld additional support (anti-sway). i used nuts and bolts to assemble the parts (and later on disassemble it if necessary)
Re: Stick Welder
as you can see the top most part has a temporary plywood platform but can still store some kalat.
and what the project looks like
my next project will be my ihawan or grill. i already have one but the parts are not welded.
sorry for the big images.
