Have rung 3 welding supplies shops regarding the Portamig, 2 have suggested I steer away from the Portamig and look at other welders, so far I have been given the options of a Jasic 200 MIG/ARC 240v, Xcaliber Autostar 180 240v MIG and Lincoln Electric 191C 240v MIG - anyone rate these machines? Too many sweets in the shop!
