Hi, have a sip topmig 170 turbo and its....well, its average.
Yes, the wire feed is shonky and I notice that it takes a lot of pressure on the adjusting screw to get a decent feed, with the result of the plastic mounting of the idle roller bending.
Now, I read on a car forum somewhere - cant remember where now dammt! that there was a known "modification" to make to the roller mechanism. From what I remember, it invoved dumping the existing adjustment and makng a little harness from flat steel/alu to hold the idle roller that clamps onto the fixing screws for the grooved roller. 2 lengths of threaded rod or bolts allowed very fine adjustment on the pressure on the rollers.
As I cant remember what forum I saw this on, I never got round to asking the guy for photos.
Anyone heard of this being done? I might give it a try myself and see what happens. It certainly cant be much wore I suppose.
Also, When welding, I find I have to use a much higher power setting than I imagined I would. thin-ish plate for car repairs required the power to be up at 4 or 5 out of the 6 positions, with the lower settings only giving the odd pulse and splat of weld. Im using 0.6 wire with pure co2 gas. I have found that using 0.8mm tips with the 0.6 wire is giving me a slightly smoother result too.
Possibly faulty windings on the transformer giving not enough juice on the lower settings? or something more mundane?
Thanks,
Dave.
