gun and ground in correct recepticals
voltage selector set to 230 not 208 (also tryed 208 setting no luck)
power at plug 240
power at switch in welder 240
power after switch(with gun trigger pulled) 235
checked all 4 diodes all have continuity in only 1 direction as needed
load tested 4diodes all check fine what could be my problem? what am i missing?
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.
i brought it to rsv welding in gr he tested it and it was fine. my wires in the garage were good enough for my hf welder but not enough to get this beast to arc proper
