10. WELDING PARAMETERS TABLE (for reference only)
Welding current and welding voltage directly influences 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.
