This standard MMA welding mode is suitable for most applications. It allows welding with all types of coated electrodes, rutile, basic and on all mate-

rials: steel, stainless steel and cast iron.

Pulse MMA

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 «Christmas 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 standard welding). This process allows greater control during vertical-up

welding.

The pulse frequency is adjusted by pressing and releasing the «F(Hz)» button and then activating the main incremental encoder. Frequency value

increases when the incremental encoder is operated clockwise and decreases when it is operated anti-clockwise. Once the setting is set, it is possible

to press and release again the «F(Hz)» button to re-link the main incremental encoder to the current setting or to wait 2 seconds.

Setting

Description & advice

The Hot Start is an overcurrent during priming to prevent the wire from sticking to the part to be

0 - 100 %

welded. It is set in Intensity and Time.
