looking for a new mig with a bit more grunt than my 100amp.
question is, how big do i need to go. i generally only weld up to around 3mm box section and angle iron, occasionally some 5mm flat bar and more often than not its all 0.8-1.2mm car body and bike body stuff.
i have been looking for a cheap dog to restore and was looking for 160 amp, which following the 1amp per thou rule dictates a rough penetration of 4mm?
but do i need 160amp as i always groove the thicker stuff anyway when i need full penetration.
