Did the previous owner weld aluminum? if so he would have had to switch polarity...

has spool gun unused polarity is good(tryed it wrong also)
also the gas is on and flowing well

it acts as if its welding "cold"
i dont think its a gound problem etheir you stike the wire on the clamp and it barley sparks.

I would be looking at the circut you have it on. if its a 240 volt how many amp is it? sounds like you need a 50 amp circut if you have it wired for a 30 amp. it would run but very weak. secondly check your cord to chassie connections. it could also be an issue.
if by chance yours has electronic channels to switch between try changing channels. I noticed on a couple of our millers they have bad channels and won't run a start cycle and the wire burns back into the tip on the first trigger pull.

check polarity, if is it was set up for flux core at some point the polarity would have been changed, at least that is how it was on my 110 wire welder.

If all else fails call this shop called CK Systematic, ask for Don. They build most of the welders that bare the snap on name. They helped me diagnoise my snap on welder over the phone and sent out parts right away. Good luck, let me know if this helps you out.
