We were out on a job with our Bobcat 225 today welding up some grate frames. We tacked the pieces of the first frame together but when we started to weld them up, we had no power output. The welder had been running for maybe 20 min. and the engine was running fine and was never shut off. We went from having output power to not having output power like someone had flipped a switch. And I mean no power to the leads or the 120 or 240 outlets.
We've been using this machine for quite a while with no problems till now. I opened up the unit and saw no obvious problems, the brushes were ok on the slip rings, the fuse wasn't blown, no burned up wires, nothing obvious. Anyone got any troubleshooting tips?
