Welder feeding or arking

If won't arc, then the feed is not moving the wire because the trigger button is not making a connection. Bad trigger. If the wire does feed, then your cable connection is responsible and needs cleaned and tightened.

It won't arc without wire in it. If the motor runs then there may not be enough tension on the feeder wheel to push the wire thru. If you had a bad kink in the inner liner it will not feed. The trigger switch in the handle applies arc voltage to the copper nozzle. It may be bad or have a broken wire.

Hi:
If your drive rollers are moving but can't push the wire all the way to the end of the gun, your problem could be the liner in your gun and/or the contact tip. Try to replace both. If your drive roller are not moving then check the trigger of the gun.

Hi:
Disconnect you ground clamp form the negative side pole and switch it to the positive pole, same for the gun disconnect the from the positive side and switch it to the negative pole.
Good luck.

check you ground cable, try to strike and ark on the ground cable, if no ark test the ground circuit if the circuit is ok you will need to have the transformer tested and for that you need some specal tools.

no ark
prolly means no bible

Make sure that the ground clamp is securely fastened to the workpiece.
Ensure that the power pin is fully seated into the housing where it receives the current.
Ensure that voltage and amperage settings are correct.

if it is new make sure the trigger is connected inside area where the wire is.

Check the earth clamp, make sure all the cables or in good condition and secured, if the unit is three phase, get an electrition the ensure all the phased are functioning. test the fuses with a meter, get back to me if all is OK

This fault is typical in most MIG/MAG Units. the feed roller/s need slackening off, pull the trigger so the rollers spin wire the wire not moving, turn the tensioning 1 turn check to see if the wire feeds, if not give a half turn on the tentioner repeat this half turn untill the wire feeds, bend the wire to the torch and pull the trigger, If the wire feeds then thats the correct setting. be awear of all safety rules. use gloves
