hi my name is phil and i am new to the forum so hello to everyone . i have an oxford mig 180 ,that i cant seem to get working properly ,i use it mostly for welding cars and the odd fabrication job ,,originally it was welding ok ,but i dont use it that often ,got it out to do a job and simply couldnt get it to work properly,every time you start to weld it just spits machine gun style and wont do a continuous weld ,occasionally it will start to weld continuosly and then very quickly it starts to spit again .so i took it over to bryant welding explained the fault and left it with them eventually it came back supposedly fixed with a bill for £180 ,when i next went to use it i found it was exactly the same ,so i took it back and left it with them again,got it back the second time had a brief try and it seemed ok ish ,but i have since found it to be just the same ,does anyone have any advice on what could be wrong with it , i was thinking of replacing the torch ? any help would be greatly appreciated thanks phil
