Hello all.. My wife and I have recently started to restore a '73 MGB. We intend to do everything possible ourselves, including learning how to paint, weld, upholster etc etc. Anyway, I've just started to weld with a Clarke 130EN gas/gasless mig welder. I've got to the stage where I can blow holes in just about ANYTHING and would appreciate some advice. I'm practising on scrap sheet steel approx 3mm thick and I'm attempting to get a reasonably straight line. Using the circular torch technique I get an irregular weld (width varying from 1/4" to 1/2"). It would appear that the torch 'spits' when the wire makes contact with the metal. This appears to be causing the relative contact position of the wire on the metal to vary, hence altering the width of the weld... Does this make any sort of sense?? Any suggestions?? Regards, B.
