Great little machine
I am a pipe welder and weld to the B31.1 spec which includes a lot of X-Ray. This machine does a great job and I also really like the fast switching between my two presets, one for 7010 and the other for 7018.
Proslove the way the machine lets you use an extended arc to wash your joint
love the autoline feature
Consonly con I can think of is the price, which in todays world it really is not that bad for what you are getting.
