I recently bought a 255 EXT..Works Great.
The only problem i'm having is that the torch is getting really hot?
Last night i was welding for about a half hour ( not continuous,couple minute breaks between welds))at 125 amps and my water cooled torch that comes with the machine was getting really hot.
I checked the cooler and it was pumping just fine.
checked to make sure the lines weren't kinked
I hate to see what it does at higher amps.
Is anyone else having this problem, or is there something restricting the flow through the torch?
