Conventional mig welding uses a metal mig wire fed through the welding torch with a separate gas to shield the weld from oxidisation caused by naturally occurring oxygen and nitrogen in the atmosphere. Gas is supplied in disposable bottles or cylinders containing CO2/Argon gases (see our accessories section on the left).

Gasless mig welding machines uses a special mig wire that includes a flux core which shields the weld from the natural occurring gases as the wire is melted and covers the weld – in the same way as the gas protects in gas welding machines.

The advantage of no gas welding using a gasless mig welder is that work can be done outdoors where it may be windy and the protection from the gas from a gas welder would be blown away. The disadvantage however is that the flux in the wire covers the weld meaning that you often can’t see clearly what you are working on. This will also have to be cleaned before painting the weld to ensure a smooth finish.

The advantage of gas welding with gas mig welders is that you can clearly see the weld pool while you are working and there is none of the associated mess with gasless welding. The disadvantage of course is the running costs of replacing the gas bottles.

If you’re unsure as to whether you will want to weld with gas or not, then choose a mig welder that does both.
