Hello all, had a quick search and nothing jumps out except maybe an inductor? ....
Some info....
Cebora 160 Mig.
Yesterday it powered up ok, as normal, nothing changed since the day before, pressed the trigger, it blew the fuse in the plug. Not 100% sure but probably just as the welder arced. Fitted a new 13a fuse, pressed the trigger - defiantly NOT arced - just standing with the gun in my hand - dimmed the garage lights and blew the fuse in the extension cable....hmmm a problem.
Removed the side for a look, all looks ok but dusty. Gave the internals a good blow out with an airline and fitted new fuse to extension.
Pressed the trigger garage lights dimmed like welder drawing massive current. There was a little spark/arc at the top of (I think) the rectifier? The thing with the aluminum plates then it came ok, lights back to normal, wire feeding, etc. Did a bit of welding - car @ power setting 4 - seemed a bit low on power and a bit more spatter than normal (using co2) but it worked.
Back at it today the power has become less and less until it’s unweldable
Side back off, all connections look ok and are tight, none are hot like a bad connection. Everything works like normal - wire, gas, fan etc - just the arc has no power. Its not hot, its done 10 times more welding in the past without a problem.
On setting 1 the wire hits the metal and glows red and melts...The power settings are working though as the initial arc changes with each setting, I suppose the closest I can describe is welding with way too much wire speed and not enough power.
One post I saw mentioned the inductor. 2 thick and 2 thin wires - 1 thick+1thin connected to earth cable - other 2 connected to rectifier?. With all disconected, thick to thick = 0 ohms, thin to thin = 0 ohms, thick to thin = open circuit. The windings are very hot? is that normal.
Any suggestions what to look at?
