-MIG (Metal Inert Gas) welding is a useful general technique for most ferrous metal work, it uses an electrode nozzle which guides filler wire from a spool and the arc is between the filler wire and the pieces to be joined. The nozzle allows a flow of inert shield gas around the working area to reduce slag creation.

-Some MIG welders can be converted for different kinds of wire, but this often involves changing the polarity of operation, so the Hackspace MIG welder is only used with a ferrous wire.
-The MIG welder can be considered a 'single-handed' welder, as separate filler-wire sticks are not used, but it is often best to steady the nozzle using both hands, to keep control over the wire being fed from the spool.
-== MIG welder shield gas ==
-Until larger cylinders are installed in the Hackspace, the MIG welder uses small disposable cylinders of gas, installed in/attached to the welder itself.
-== MIG welder capacity and rating ==
-== MIG welder power supply ==
-A standard 13A plug is used, so this welder can be used with any of these sockets in the metalwork / welding area. The power is controlled by a switch / trigger in the nozzle, so a no-volt release supply is less important than with the other welders.
-RFID control of access will be installed shortly.
