Co2 Welding Basics. PREPARING FOR THE WELD. To be noted it is a sort of arc welding process that can be both automated or semi-automated.
This gas shields the weld as it forms. PREPARING FOR THE WELD. The MIG welding I am going to describe in this instructable is for steel which uses a copper colored wire.
In this particular unit the critical setup to know is that the wire size is 035 in.
The flux core welding method is not totally different from arc or MIG welding methods. The tank is either 100 Argon or a mixture of CO2 and Argon. The reason behind naming it a flux-cored welding is that a wire made of flux is used to weld by this process and this is what covers the whole weld. When welding metals are melting creating large amounts of heat during this process heat attract moisture oxygen from the immediate environment and this will cause the weld to become very brittle.
