help with faulty wire feeder

[fozzone]

I havent used a mig welder for a number of months. Switched on yesterday power got to the unit but when I pressed the trigger the wire spool didnt move. Looking at the bits that came with the unit there is a small low amp fuse but no where to put it from the outside. I can only assume the casing needs to come off and the fuse swapped out. Has anyone else found this to be the solution or can you think of any other reason why the wire no longer feeds throught. I've checked the tip and it isnt fused. The wire feed when running normally would make a sound but in this case it is deadly silent

thanks in anticipation

To find out if the wire is stuck, release tension on wire feed roller and press trigger again, if driven roll turns the wire is stuck, if not the problem is most likely electrical

Take the torch apart and short the trigger connections, it may be as simple as the switch is faulty. Just out of interest, you say there's power to the unit, if you press the trigger and 'strike' the contact tip against the earth clamp, does it spark or is it just that the power light is on?
