Hi all... Been reading the forums for a while now trying to get some tips for welding. Finally bitten the bullet and started welding my mk1 golf. Started on the easy stuff of welding up the bumper mounting brackets as I'm fitting some early bumpers that don't need the mount holes.
Anyway, i digress! I got a cheap (and I mean very cheap!) second hand Clarke Pro 90 which should be ideal for thin bodywork panels. Gave it a bit of a service (new liner, tips, shroud, earth clamp etc) and started welding.
It seems to be fine apart from the wire feed speeding up & slowing down which makes welding pretty tricky (especially for a complete novice!)
Any ideas what might be causing this? Motor, pcb, earths? I have had the multimeter on the motor and it only fluctuates by at most 0.05v when loaded which I wouldn't have thought would cause the problems I am experiencing.
Without a load on it (ie the wire clamp removed) it seems to have a constant speed (sound stays constant) and volts fluctuate again by less than 0.05v.
I have greased the wire holder spindle but that hasn't helped so I am at a loss now...
Any help greatly appreciated as my welding needs all the help it can get for now!
Thanks
Alex
