[TheForge] welder woes

[Larry and Pat Brown]

Hi
I would start by checking the input voltage from the breaker. You should 
have 220+ across the terminals on the breaker and 110+ from each to 
neutral. I think this machine needs a 40 or 50 amp service and #6 wire to 
run well. I am trying to remember as it has been 20+ since I had one. If 
the fan runs and it is clean you may have had a winding short out, the 
input current is very important in this machine, if you have the proper 
current in and you have a short, the bad winding should get hot fast. Take 
the cover off, turn on, turn off soon, UNPLUG!, check for hot spots 
carefully. If it trips the proper breaker and feed lines I would price 
parts and a new machine before proceeding. Be careful, remember what it 
does to metal rods ;-)
