Hi all, I've been a reader for a while however I've had to make a first post to consult the hive mind.
I've a good wee 2nd hand welder but it's always had a dodgy wire feed which as you'll all know totally flux things up.
Everything from the motor, gearbox, liner etc has been checked, cleaned, replaced as required so please no replies on this.
The motor seems to be getting both AC and DC which I believe is what's causing the issue of a barely perceptible speed flutter at the motor which when passed through the gearbox is an obviously fluctuating wire feed resulting in spits and spots almost like intentional stitch welding but with a continuous trigger pull.
As the motor gets its power from the bridge rectifier could this be faulty?
It is impossible to check each of the 4 diodes individually as they are spot welded in place.
Or possibly there is a bad diode on the wire feed control board...
I have read a few similar posts without a satisfactory fix.
Any clued up suggestions gladly received.
