Mma Pulse - GYS PROTIG 201 AC/DC Mode D'emploi

Translation of the original instructions
COATED ELECTRODE WELDING (MMA)
CONNECTIONS AND RECOMMENDATIONS
• Connect the electrode holder and the earth clamp into the connectors provided for this purpose, taking care to respect
the welding polarities and intensities indicated on the electrodes boxes.
• Remove the electrode from the electrode holder when the machine is not in use.
• The machines have 3 features exclusive to Inverters:
- The Hot Start creates an overcurrent at the beginning of the weld to prevent sticking.
- The Arc Force creates an overcurrent which prevents the electrode from sticking to the weld pool.
- The Anti-Sticking technology makes it easier to unstick the electrode from the metal.

MMA PULSE

This MMA Pulse welding mode is suitable for applications in the vertical up position (PF). The pulse mode keeps the
weld pool cold and eases the transfer of matter. Without the pulse mode, vertical-up welding requires a difficult "Christ-
mas tree" shape triangular movement. With the MMA Pulsed mode, this movement is no longer required and a simple
straight up movement is enough (depending on the thickness of the workpiece). If you wish to widen your weld pool,
a simple lateral movement is enough (similar to normal welding). This process allows greater control during vertical-up
welding.
TUNGSTEN ELECTRODE WELDING WITH INERT GAS (TIG MODE)
CONNECTION AND ADVICE
• TIG DC and TID AC welding require gas protection (Argon).
• Connect the earth clamp to the positive connector (+). Connect the torch to the negative plug (–), the trigger cable
and the gas hose.
• Make sure that the various components that make up the torch are present (clamp, collar support, diffuser and nozzle)
and that they are in good condition.
• The electrode selection is defined according to the TIG DC or AC welding current..
ELECTRODE SHARPENING
For optimal operation, it is recommended to use a sharpened electrode as follows:
