Hi all, I am currently using a plasma welder with 96%Ar+4%H2 penetration gas, 100%Ar shielding gas and 100% N2 purging gas. My welder power was set to 351Amp, 29.4V with a welding nozzle 4.0mm.
And I noticed there are small lumps in wavy pattern on my weld line.
Can someone give me some advice whether this is due to purging gas or any other factor ?
Thanks guys.
