Sure, you'll need to buy some specialist silicone bronze MIG wire and some pure Argon gas, but silicone-bronze MIG wire allows the MIG welder to be used for some normally very delicate jobs reserved for the oxy-acetylene gas torch.
Butt joining 1mm thick galvanised section or vehicle panels is normally difficult with a MIG welder without distortion. Likewise, joining two different metals would be just as hard.

It is one of our monthly 'From the Workshop' articles which will appear in the July edition of Farming Ahead.
