Alphatig 200x TIG welder #6: More from vintagespeed.

 Another update from vintagespeed from ADV Rider on his Alphatig.

 so here's some pics of my boogers after a 120cu/ft bottle of argon; ~ 1.5 tungstens and about 6hrs run-time.

i know it's not good, but it's my experience after 20+ yrs MIG and stick welding and never picking up a TIG machine before. i think at the end of the next bottle i'll be much happier with the results. and i'm going to pick up some stainless too, that's where the pretty welds reside.

here's a 3/32 - 1/8" gap i filled in some mild steel of different thickness, 1/8 on top of some 3/16". you can see where i undercut the hell out of the 1/8":


definitely NOT stacking dimes, but i'd put it in service:


next up i really layed into it and cranked 'er up to 200amps and setup some 1/4" plate on 1/4" angle. i was probably mostly 1/2 to 2/3 pedal though so wasn't using the full monte and the torch got H O T for sure, smoking a little bit even ,here & there:


you can see where i dip'd a few times, and i didn't prep the 1/4" AT ALL, full mill-scale. i was also welding with the garage wide open and not caring much about shielding gas dispursement, hence the pock marks in spots:


so there you have my review after about 6hrs on the machine. so far so good. my AC is actually MUCH better than the ugly DC results above, but what good is a welder if he can't do both? i'll keep practicing. so far, i like this machine alot, it'll never replace my MIG for DC but it's a great machine all around.
