10 . MIG WELDING PARAMETERS TABLE (for reference only)
Welding current and welding voltage directly influence the welding stability, welding quality and productivity. In order
to obtain good welding performance, the welding current and welding voltage should be set optimally generally
according to the electrode diameter, the mode of metal transfer and the production requirement.
Set the welding current and welding voltage according to the below tables.
