Hi all. Quick question. I have a Lincoln Precision TIG 375 that was recently connected in my garage. I can weld without incidient using this welder at various amperages. However, AFTER I finish welding (2 to 4 minutes after) - the breaker trips. This is currently a 90 amp breaker that I will be upgrading when I intend to use the full capacity of the 375, but for my current settings should be holding with plenty of cushion. I have never tripped the breaker DURING the weld or even within seconds after - only more than 2 minutes after.
Anybody seen this type of breaker tripping problem before and if so what's the problem/solution?
Thanks in advance!
Kevin
