Re: Inverter - slag hard to come off on stainless steel

i see esab actually list a weld voltage for those rods. to me at the moment it does seam to require a high run voltage. so i wonder what the inverter welder is like running 6011? if its got a cel or 6010 mode try it on that. I never welded with 6010 or 6011, in Portugal it's a pain in the ass to fi...

Re: Inverter - slag hard to come off on stainless steel

i take it you havn't put a meter on to check. i doubt its 70v welding voltage. might be 70v ocv. inverters are not as predictable in their welding voltage like transformer machines. the ocv on the rod box relates more to transformer machines. did you try increasing amps? sorry i should have asked e...

Re: Inverter - slag hard to come off on stainless steel

try dropping your amps a bit. AC is a bit cooler than DC. I did that, 45, 40, 35, 30 amps... the problem remains. I've been searching the internet for answers, and i got to the conclusion that the high voltage might be the problem, my inverter welds at 70v, on the rod's box appears 50v on the descr...

Re: Inverter - slag hard to come off on stainless steel

SS stick weld slag is notorious for coming off hard. Biggest thing is let cool and it will start to pop off all on its own, it’s designed to work like that. Until the weld is cool enough you will just fight it, if you tried to get it off when it was still hot then it usually looks like your picture...

Inverter - slag hard to come off on stainless steel

Hi, i'm an hobbyist welder, i'v been welding with a 30 years old buzz box for the last months, it's heavy and kind of tricky to weld with it, so i bought an inverter ( Nutool 140 AMPS), it burns rods like butter, when welding normal steel it works very well, but with stainless steel it's a different...
