7. 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.
