Recently set up a new tig to use at home. It is a Cigweld 170amp inverter. Having some problems with welding stainless, I am getting a heap of scaly crud on the weld surface, this then spits off and hits me when it is cooling....
I have some pictures to show the problem - first up, to show I am not a complete nong is a weld I did at work
This is 316L and is a 8mm 0.7mm tube in a piece of 0.9 plate welded with a esseti 150A inverter (yes this has been sandblasted)
This is a problem piece, 0.7 tube in a 1/4 BSP bush again 316
you can clearly see the scale left on the weld.
Stats -
DCEN
25 Amps
2% Thoriated 1.6mm electrode
BOC Argoshield Universal at 12lpm flow
The spitting scale is also occurring when I weld black mild steel.
Anyone have any thoughts of where I am going wrong?
