User manual
DownSlope adjustment potentiometer
The «DownSlope» potentiometer is used to adjust the current fade value (clockwise increment and counterclockwise de-
crement). The value is visible on the 7-segment display and remains displayed for 5 seconds if an action on the potentio-
meter is performed. The minimum value is 0 sec. and the maximum value is 20 sec.
Cold current adjustment button
When one of the 2 processes «HF TIG» or «LIFT TIG» is selected, the cold current setting button is used to adjust the va-
lue of the cold current (only in «4T LOG» or «PULSE»). The value can be adjusted between 20% and 80% of the welding
current. The incremental step is 1%. The default value is 50%.
In MMA mode, the Arc Force is indexed from 0 to 80% (0= no Arc Force / 1 to 80% = Arc Force setting possible).
The default index value is 40%.
WELDING WITH RUBBERED ELECTRODE (MMA MODE)
CONNECTIONS AND RECOMMENDATIONS
• Connect the electrode holder and earth clamp to the corresponding sockets.
• Ensure that the welding polarities and intensities indicated on the electrode packaging are observed.
• Remove the electrode from the electrode holder when the machine is not in use.
CHOICE OF COATED ELECTRODES
• Rutile electrode: very easy to use in all positions with DC current
• Basic electrode: used in all CC positions, it is suitable for safety work due to its increased mechanical properties.
MMA STANDARD
This standard MMA welding mode is suitable for most applications. It allows welding with all types of coated electrodes, rutile, basic and on all ma-
terials: steel, stainless steel and cast iron.

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.
The welding current is adjusted according to the type of electrode chosen (refer to the electrode
10 - 220 A
packaging).
The Arc Force is an overcurrent delivered when the electrode or drop comes into contact with the
0 - 80 %
solder bath in order to avoid sticking.
