4 GAS METAL ARC WELDING
The process is available for certain machine types.
Main menu → Process
During Gas Metal Arc Welding (GMAW), an arc melts a continuously supplied wire. The weld
pool is protected by shielding gas.
When the Gas Metal Arc Welding (GMAW) process is selected, you can choose between two
control methods by marking REGULATION TYPE using the positioning knob and pressing
ENTER. Choose between constant amperage CA or constant wire feed CW, see explanation
in “CA, constant amperage”, page25 and “CW, constant wire feed”, page25.
