The above information is not correct.

The entire wire is polarized by the tip during normal operation, making the entire supply of wire is polarized to whichever polarity is selected. The cabinet of the welder is usually bonded to the output, and so therefore is the spindle on which the reel is kept.

You are using a spool that has the wire anchored on the outside of the reel, rubbing on the spindle assembly, and making a sliding contact.

Put an insulator between them. A circle of thick cardboard (not corrugated) with a hole in the center can work well, as do plastic lids- Cottage cheese, tub of grease...

If you can feed the wire manually(by hand) the liner should be OK. I would replace the tip and verify all the welder connections at the drive wheels. Make sure all the connections are clean and tight.

I HAVE A LINCOLN 175 MIG WELDER THAT WHEN I GROUND IT AND PULL THE TRIGGER THE WIRE GETS RED HOT AND BREAKS AT THE FEEDER. I DON'T KNOW WHAT THE PROBLEM IS.


Hello, do you have the welding tip in the nozzle? This tip provides the proper grounding of the electrode wire.

I have a lincoln sp-175plus, when trying to weld it the arc just melts the wire and it balls up at the end. I also put a new contact tip in. As well sometimes the wire feed just stops. I then press...


Your drive tension is too light. There are rollers that the wire feeds through and they need to be tightened. They should push the wire through the gun but slip if you put the tip against a solid object and pull the trigger. If they do not slip, they will jam your gun. Give the tensioner another turn.

I have a craftman mig 110v mig welder arc problem


Check to make sure the contact is not touching the nozzle of the mig welder. This would definitely short it out!

My little 110 mig welder is arcing without trigger pulled


i believe that the trigger only send out the wire and does not control the arc the tip should be live as long as the welder is on

No wire feed


If the power to the unit/fan is on and the relay clicks the fuse is not the problem. Check your motor connections. Either you have a bad motor/wiring to motor or motor speed control board.
