I have a mig that I do not know the make of and I am new to welding and I am haveing trouble geting it to work well. I have noticed that the wire feed motor is arcing when the triger is pulled but the speed controler is working and the wire is comming out. the motor in question does have external brush caps to replace the brushes I have taken them out and the brushes are about 100 mm long is thisto short and causing the problem ? and if so where can I get replacment brushes ?
Thanks
