hi group. hoping to elicit some preventative medicine. have a 3ph 300V mig welder (weldtronic -
a few days ago its started emitting a highpitched squeel. well, lets say 'buzz' ... sortof like those old buicks when you leave the doors open.
it still works fine, but since its never made this sound before, i'm starting to get nervous.
based on that limited info, anyone take a stab at what it might be? i've heard capacitors make this sound before, and i'm afraid it might kick out on me. i'd like to take some action before i'm stranded.
no more warantee.. and there aren't any service shops anywhere around (i live in the middle of nowhere and would have to drive 3 hours to get it inspected.. since i'm in europe, that means i can kiss it goodbye for a good 2 weeks easy).
thanks,
-tony
