I have a 140 Cigweld Arc Welder that I'm learning to weld with. In mid weld/use welder just cut out but light is still on. Have no idea what happened just that the noise that the welder was making had stopped and no more welding. Help please!

SOURCE: I have a Lincoln 140 mig welder. It welds and cuts

Usually this is caused by a bad liner in the mig gun hose, or worn out guide rolls in the drive unit, or if this is not the case the speed of the wire might be set to high as this would force the wire into the weld causing the motor to heat up from resistance and shut it down on safty. Hope This Helps Don

SOURCE: no arc on my sip 195 mig welder, was welding then it stopped arcing, every thing else works fine,tried it after a couple of hours still no arc. any idea what it could be.Please help.

Internal fuse inline with the transformer output to the gun.

SOURCE: old AC180T welder has a weak arc no weld

Are you using cored wire? Or shieldgas? if the later, you may not be getting any to the gun.

If you are using solid wire without shield gas, you will get what you describe.

In the off chance you are using the correct combinations, you may have a loose connection in the circuit that adding resistance to the circuit and lowering the effective voltage at the tip. Make sure all connections are tight inside of the machine as well as the cables and gun assembly as well.
