CZ550Kevlar Posted March 30, 2020 Report Share Posted March 30, 2020 I have a NEILSEN CT2228 ARC welding machine. it`s cheap and simple but has served me well.... problem is i lent it to my Dad for him to do some welding and i`ve just got it back from him and he has over adjusted the AMP dial, it was set to exactly the right ampage for the rods i gave him but either him or someone has dialled it right up off the scale and now hen i try and reduce the ampage the little marker ontop doesn't move and it seems stuck on mental arc power and now cuts rather than welds. Anyone got any clues how i can rescue it?? Quote Link to comment Share on other sites More sharing options...

Diver One Posted March 30, 2020 Report Share Posted March 30, 2020 If it's like my old (40+ years) 130A SIP over cranking it can make the sliding bit of the winding become detached Quote Link to comment Share on other sites More sharing options...

CZ550Kevlar Posted March 31, 2020 Author Report Share Posted March 31, 2020 (edited) Wound it in and out and as you can see the plate moves backwards and forwards but also the red flag slides too so i don`t know what the default position is and where it should be to "zero" it. Ampage window on top is 55 to 160 Edited March 31, 2020 by CZ550Kevlar Quote Link to comment Share on other sites More sharing options...
figgy Posted March 31, 2020 Report Share Posted March 31, 2020 (edited) Wind it down as low as it will go, see where the indicator sits. If it's out move until it sits on 55 amps. That's if the amps have gone down. Also every packet of rods has its amperage to weld on it, pick somewhere in the middle and try it.

oldypigeonpopper Posted March 31, 2020 Report Share Posted March 31, 2020 (edited) hello, it was usually low power turned wheel far left, will it turn both ways free ? while you have top off put some grease on the spindle, all these types do look very heath robinson but 1000s were used before the hobby migs came about, Edited March 31, 2020 by oldypigeonpopper Quote Link to comment Share on other sites More sharing options...

CZ550Kevlar Posted April 7, 2020 Author Report Share Posted April 7, 2020 (edited) Yep and not lend it out. For some reason my Dad decided that the setting i had left it on wasn`t right and wanted more amps and it didn`t weld it just started acting like a cutting torch.
