Warpage - in all welding materials and types - is all about heat control... and that is FAR harder to learn than "melting metal and adding filler"...
Doing stainless sheet -- with PERFECT fit up -- you can tack with a quick stab of the foot control - no filler... just a very quick "zap" and you're done... and even that will pull the gap off... so you have to tap that gap back before you move on.
I only use a foot control -- I put the finger control away and have never gotten it out since. I have to steady/rest my torch hand and filler hand --- or fugedidaboudit.
See any warpage in this tank I made?
