Eastwood Mig 135, Overheat and now no fan.

[guinelle1]

had my eastwood mig 135 for a while now. well i actually own two of them. and i seemed to praise them so much now i think i might of burned one up. i never hit the duty cycle on it before.. even after welding a whole new dump trailer floor in basically non-stop on max power... yet i make some 2 inch welds and the machine quits (thought i blew breaker) but its still on wont feed and the fan cut out. waited about 10 min and now it welds but the fan doesnt work anymore. I dont think eastwood will warranty it since i bought this one 2nd hand. and i know parts are not available through eastwood. but there is a local welder repair place near me that WILL work on them... not sure if its worth it though. im willing to tackle it myself.. but really what am i in for?

If it welds then just install a new fan.

is there a circuit breaker on the back? open it up

On some the fan is not only a typical fan for moving air but also a transformer to provide low voltage to the control board.

my plan is to open it up and check for power to the fan, not really sure. the fan usually came on all the time.

i cracked her open today and i was quite suprised on the construction of this machine. everything looks pretty well put together inside, even though its all crammed in there. the fan is a royal pain to get at, but i spun it over with a screwdriver and it seemed hung up. id flick it on, spin it it would spin and hang up again. it seemed like it had a bad spot in the motor. Im almost positive there was nothing stuck in it. i was able to get it spin on its own and let it run for about 2 hours with the cover off. now it seems to start up fine.

It is possible you got it so hot the plastic in the fan melted. This kind of over heating can kill a welder.

Hello, was wondering if guinelle1 still had the little 135 mig . . . I picked one up that needs the fan replaced, oddly enough. I have the fan but no clue about assembly. Contacted Eastwood and they didn't have any pictures that help, or wiring diagram . . . which I find rather frustrating. Hoping you have picks of inside casing . . . diode/fan area. Thanks in advance!
