Hello everyone!After taking a new job in GA, I sold most of my shop equip. I hung onto my PT275, and a few other toys.I've attempted to get the PT wired up in my garage, but I'm having some issues. It's tripping the breaker every now and then when I turn the welder on.I ran a 100amp subpanel in the basement directly below the opposite wall of the garage where the welder is located. I then ran a 60amp disconnect box in the garage, and wired it up with #4 wire for power and #6 for the ground.I drastically overbought when I snagged the PT275....I rarely get it above 150amps on my power meter when doing aluminum. I mainly weld thin diameter stainless tube. I'll never need to pull serious amps from the machine, and know that it would trip the breaker if I stood on the pedal at high output.My problem is about every 3rd or 4th time I power the welder up (turn it on), it trips the 60amp breaker on the subpanel. I'm curious as to why starting the machine up would pull that kind of current?I also now have a problem with my water cooler. When plugged into a wall outlet, it runs fine. Plugged into the back of the PT, and it won't turn on. It also instantly trips a GFI protected wall outlet if I try it there.The cooler had been used for a year or so in my shop, and nothing has changed on the wiring with it.Please help if you can I'm ready to sell this thing and get an inverter, but I really can't afford the hit I'd take on selling it (new on ebay for under 2K...and then the inverter is going to be 3K +)
Reply:Well, I figured out what was wrong with the cooler The motor case needs to be grounded to the chassis of the welder, and the bonding wire I had used had a bad connection.One problem down, one to go |
