The issue I need help with is that when i am in tig mode and press on the foot current controller the circuit breaker trips out. This happen usually 1 out of 2 or 3 times. Sometimes it will trip out at first time, sometimes it will not happen until the third time. it will happen most of the time when I press the controller, disengage and press it again with in a few seconds.
When in the stick mode it will trip out at about the same frequency (1/2 - 1/3 times) when first turn on. But once it is on, it will stay running over the full range of current setting using rod sizes up to
5/32 on plate steel up to 1/2 inch.Welder Data: Build 1984 to Code 8888 pre lincoln electric co per s/n on welder.
Installation data:
-circuit breaker (new) = 100 amp
- AWG #2 15 feet
-House feed is 200 amp.
Trouble shooting done so far: Cleaned breaker contacts and buss bar. retighten wire connections at breaker and welder Contactor 'contact' appear clean and not burnt or corroded but have not cleaned yet.
IMHO the issue appears to be related to the contactor engagement curcuit.
Any additional ideas would be GREATLY appericated.
Sincerely, Noble
