Advise please. I read a few reviews today on mig welders and the Sealey MightyMig 150 seemed to be a good machine at a reasonable price. I have just read the migwelders buyers guide and I am now not so sure. Are machines like Parweld, GYS and Rtech that much better and worth the extra money? I am planning a restoration of a Land Rover Defender and a Series 3 utility truck.
