What Welding Wire To Use

Hi guys,

6 months ago I got a new Lincoln Weld Pack 3200 and have a quick question. I have it set up for gas not flux cored. I used the small spool of wire that came with the welder (.025) and need some more. I am welding body panels along with mild frame repairs and misc stuff.

Can someone please explain what size wire is used for what applications? And what would be a good all purpose wire that I can use on all of the above mentioned stuff. A couple of years ago someone gave me a new large spool of .022 wire and I hate to waste it, will that work on everything as well.

By the way I really like the welder. For a 110 unit it works great although for the little more it would have cost I should have gotten the 220 version. Oh well not complaining just my 2 cents. Thanks again guys.

.023 is the most versatile size, for general fabrication. A good welder can weld up to about 1/4. It welds great sheet metal. Just buy mild steel wire.

I agree,.023 is all you need with that welder and .030 is simply too big even if it does seem to weld ok with it. Using .030 will put you into a maximum current condition and will result in very short duty cycles so if you are trying to weld something like a frame it could be a problem, could be done but .023 will work better. There is no need for the .030 on anything you are going to tackle with a 110 welder anyway since you can weld just about anything if you are willing to spend a little more time and use a couple of tricks. On anything heavier than body panels up to about 1/8" it will work just fine but over that you need to preheat the parts with a torch (this should be done on frames and spring hangers for example) to about 350-400 deg (just too hot to touch with your bare hand) to prevent thermal shock and brittle welds. If you do this and use multiple beads for heavier stock there really is no limit to how thick you can weld with that machine, heck you could weld 1" thick parts just fine if you are willing to put up with the short duty cycle and keep the parts hot while waiting for the welder's cooling periods.

I build T Bucket frames with 1/4" and all I use is .023" wire. The .023" works just fine.

.023 or .030 I think would work fine. The .023 would be better for 1/8 and thinner. You want to use ER-70s-6 and 75/25 mixed gas. That will cover anything steel you want to do. If you get up to 1/4" the you'll need to be careful of your joint configuration and make multiple passes.
