My name is Eric Henderson and I own a Linde 160 Autoweld mig weld

You should be able to get any replacement parts you want through Air gas / ESAB.

you need a multi meter to test it, does it blow the fuse the second its switched on or when you pull the trigger, it could be the small transformer that powers the pcb, gas solenoid ,fan contactor or at worst welding transformer

switch from tig welding to mig by switching your current from AC to DC for mig. change from your tig gun to your mig gun. turn water flow off. proper ground and weld away.

Potentially, I would tighten tension on the feed wheels slightly first and see if this improves it. Also blow out the cabinet on a periodic basis as debris can also build up in the knurlings of the feed wheels. If it does not, pull out the liner and check it for kinks or other damage.

There is a small chance the transformer burned out, but more likely the switch has dirty contacts or burned out. If you turn the switch through all heat positions 2 or 3 times before you start welding in the morning, it should remedy it in the future. In the short term, spray some contact cleaner (or even WD 40 in this rare instance) into the heat selector switch and rotate it through the ranges a number of times to remove corrosion from contacts.

Will the wire arc when dragged across the ground clamp? If not- there are internal fuses in the machine and they may be loose or blown. There should be one in series with the "hot side" (the gun) of the circuit and sometimes on the ground clamp side of the circuit.

There is a small chance the transformer burned out, but more likely the switch has severely corroded or dirty contacts or the switch burned out.

Just to make sure it is not the trigger switch, unplug the gun from the connector. With a clip try to bridge up the connector, if the motor does not turn then your gun trigger it's fine.

A new motor can be order it at any of your local welding stores. Try Praxair.

Need to ckeck the gun switch trigger the terminals? See if there are grounding out.

Your foot pedal should adjust the current, just like a sewing machine. If it is not working either the foot pedal is broken or your welder isn't compatible for the foot pedal. Some welders are only strike starting with no variable control amperage (usually your lower end models).
