I have no gasflow it sounds as if the gas is leaking at the feed rolls


there is no seal at the feed rollers around the wire as it requires the correct gauge wire and feed hole to slow down the loss of gas at that point ( easier for the gas to escape up the wire housing and out the welding end )
the gas is allowed to flow when the welding trigger is operated as that opens a gas solenoid that allows gas to the welding wire tube to exit past the shroud around the welding point

read you user manual well to be acquainted with the machines operation, and if there is a persisting problem talk with your supplier and consider a warranty service check

Weld-pak 100 Hd Problem


There is a reset button located in the wire feed spool compartment,
check to see it stays in when pushed. It is a safety when the machine
overheats, it normally resets when machine cools off. If it is working properly I suggest contacting Lincoln Electric Dealer for service.

Lincoln 140 hd turns on but doesnt feed wire when trigger is pressed


Hi:

Try by-passing the trigger switch by disconecting the trigger cable cord (not the gun) and using a wire bridge the connector at the machine, if the motor turns, then your problem is the gun switch, that's an easy replacement, if not then you have a problem with the motor itself or the pc board and you will need to sent it in to a pro for repair.

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.

Check the voltage at the wire feed motor when the trigger is pulled.

I had a Weld Pak 100 that with 0 volts at the wire feed motor, and the problem wound up being that 2 of the big power (stud) diodes were shorted.

Wire doesn't feed


Either the trigger mechanism in the gun is bad, the servo that turns the feed wheel is bad, or you have too much tension on the adjustable tensioner knob. Take the wire out of the feed wheel, plug unit in and see if you can get the wheel to turn. If not, it is the trigger or the servo. If it turns, the tensioner was too tight.
