Your migatronic should be spot on for bodywork , is there any one local on the forum could come around and have a look ?
That would be ideal!Your migatronic should be spot on for bodywork , is there any one local on the forum could come around and have a look ?
Cheers for the advice mate I'll give it a go tomorrow.I know on my migatronic I used to use .8 wire, wire tensioner on the wire roll backed off ,by that I mean the nut in the centre of the wire spool holder , not the wire feed roll, power on no.2, and just fine tune the wire speed so you could spot it, if you get it right it should just glow red hot with out blowing through, then move along and repeat , got to be fussy with the wire speed to get it right , and very short burst on the trigger. sorry not local so cant offer to come and have a look.

Regarding the kempii, if all operational would a good clean, new torch and earth cable/clamp get it back to "new"?
Don't forget when butt welding fit-up is key, if the gap (you are leaving approx 1mm gap?) in inbetween varies then you need to adjust your technique to compensate - that's experience so start off by maintaining as consistent a gap as possible.
I have been just about getting away with using a voltage of "2" by being very very careful but is time consuming and bloody annoying.
True! But I'd rather just have a voltage between 1 and 2! I read on these forums about potentially fitting a "dimmer" to a transformer unit to fine tune the voltage. Anyone have experience with that?You'll get better at it with practise though and patience is a virtue
+1I think your gas mixture, with 12% CO2, is Argoshield Universal, and that is typically used for 4mm - 10mm steel. Thin steel normally uses a "lighter" mixture, such as 5% CO2
This has been tried, with limited success. The generic eBay "5000 Watt Dimmers" are designed to control lamps - a resistive load, not the inductive load of a large welding transformer. The trigger for the controlling TRIAC goes out-of-sync with the AC voltage waveform, and ends up missing alternate half-cycles. This effectively feeds half-wave-rectified DC to the transformer, which does not like it and becomes very noisy, making a loud buzzing sound. Even when working, the range of power adjustment is very small. This modification has been tried on cheap MIG welders with just two output power steps - e.g. 50 or 100 Amps, but a correctly functioning Migatronic should not need it.I'd rather just have a voltage between 1 and 2!
