Wire feed problems

[cruizer]

I think thats 50K ohms, never the less, likely a charge cap issue, unsure why your replacing parts willy nilly. Send the board out for over haul.

Did you disconnect the wires from the pot before measuring? If not you would get bad readings like that.

I have a miller matic 135 that will only feed wire at high speed I replaced the Q1 transistor and the speed pot reads 50oms when it is set at 0 and slowly goes down to 0 when turned up can anyone help
