8.WELDING PARAMETERS TABLE
The option of the welding current and welding voltage directly influences the welding stability, welding quality and
productivity. In order to obtain the good welding quality, the welding current and welding voltage should be set optimally.
Generally, the setting of weld condition should be according to the welding diameter and the melting form as well as the
production requirement.
The following parameter is available for reference.
