Welding Tips and Tricks

Just learning to tig and have tried about a dozen or so welds on some flat & one on abit of 3/4 medium black pipe,welds are on 1/8th flat using 2.4mm electrode with er70s-2 1.16th filler except no#7 is er70s-4 which l liked better all weld at 120 amps,just after some thoughts on what L have done,no#7 l used the e type technique like l use for mig.
Opions of the welds please and any advise on improvement.








And just a palm rest for the vice

wanaweld,
I think you are on the right track. First check your argon bottle, that yellow smoke indicates flow issues.

Second, I believe you are to hot and to slow. Amperage may be fine if you move faster/dip faster or more.
Watch the top edge of the puddle, if you see it nipping away at the top plate, as seen especially in 4 and 5, either back off amperage, change torch angle or add more filler to smooth out that "undercut". I think you are doing very well.
