7. Welding function operation
Warning!
Before turning on the power supply make sure that the electrode
holder or welding torch is connected to the output, do not touch the
workpiece and earth clamp. Otherwise, an unexpected arc may be started
when the power is turned on in the case of MMA by default. This can cause
damage to the workpiece and to personnel.
Warning!
Be sure to wear appropriate protective equipment during welding
operation. Arcs, spatter, smoke, and high temperatures produced in the
welding process may cause injury to personnel.
Warning!
After the power supply is turned off, the output voltage of the
welder may continue for a period and then drop slowly. Please do not touch
the conductive part of the output before the panel is extinguished.
7.1. Function table
Rotate the encoder to select different welding parameters as required. Regardless of no-load
or welding mode, parameter selection and adjustment can be carried out without affecting the
welding. Switch the mode by rolling. "●" indicates that the parameter is optional, and "×"
means not optional.
