Lincoln 175 SP+ Question

My Lincoln 175 started doing the same thing after about a year. I suspected dirt or galling of the wire in the cable. I clamped a bit of paper towel that I had sprayed with WD-40 around the wire before it goes into the cable. It seems to have solved the problem. The small amount of WD-40 doesn't intefere with the weld (at least on my backyard welds).

are you using some kind of tip dip [cleaner]?

Nope. Welded again this morning for a couple of hours, and all was fine again.

mine had a sticky trigger switch... was just a coincidence the tip cleaning gel seemed to help

I had a similar problem with my SP-170T. I went to use it one day and it spit out about 1 inch of wire and then stopped completely. Mine's simpler than yours because it doesn't have variable voltage but there was a connector going from the gun switch to the control board that I reseated and it's been working fine ever since. I think we've run through 2 10 pound rolls of wire since then without a single problem.

As for duty cycle. My son uses it pretty heavily building custom truck bumpers and he's never hit the duty cycle. We run .030 wire most of the time though and never anything thicker.

Okay, next dumb question. What happens when you hit a duty cycle? Does it just shut down all together?

Steve

Then it wasn't hitting the duty cycle. It was acting just like a spot welder.

Are you sure you didn't have a sharp bend in the cable with the wire feed in it (not the ground) ... or worse, standing on the cable ?? (had to ask) If the wire hangs up, the feed motor for it "trips off" until you release the trigger and pull it again (releasing the trigger resets the drive motor control). If there is too heavy a "load" on the wire feed it will do that.
