Tig on mild steel question

admin

Still debating if the new Lincoln Tig 185 is right for me.  Will it be capable of tig welding various joints on 3/16" cold rolled steel?  I've looked all over Lincoln's site and can't seem to find this.
Reply:In most cases on 3/16" steel, I d use MIG instead of TIG. To answer your question though. Yes, The Lincoln 185 will be able to TIG  3/16" steel. Keep in mind though that you are looking at using the machine at potentially 150+ amps depending on the joint design.ESAB Migmaster 250 Hobart Ironman 230Multimatic 215TWECO Fabricator 181i & 211iHH125EZ - nice little fluxcore only unitMaxstar 150 STH - very nice
Reply:Like Dan says, it's not the best way to go. MIG will be much better, and if it were thicker, say 1/2 to 3/4, CRS tends to crack with TIG, if you're not careful.Experience is the sum of our mistakes.  Arcin' and Sparkin' Rocky D
Reply:3/16" and thicker....I'd stoke up the stick machine !......No muss,  No fuss  !I'll be the LAST one to let you down !
Reply:sublime: mig would be the fastest then stick, but if you just wanted to tig it then do it in multiple passes. You won't have to try and carry a big hot puddle  that can cause to much stress.            revpol

Reply:Originally posted by Rocky D don't know for sure, Jack....just know that it does.  I know, you expect more than that from me....truth is, once I learn these things, I just accept it and move on. I'm not much of a scientist.   My guess is that it's due to the way it is formed....probably has a lot of stress in it, from the mill.
