Arc Force
Pulsed MMA welding – the welding current oscillates between a high and a low current value
allowing less thermal input in thinner plates and greater arc control in the most demanding
positions (vertical ascending).

FREQUENCY
- Adjust the current value to the diameter of the electrode (Fig.1 - 2), according to the
following table, to adjust the machines according to the electrode to be used and start
welding

Adjusting current scope (Amp)
7.2 -TIG WELDING MODE
- Make the necessary connections to mains and earth as described in "Installation".
- Connect earth cable to positive plug by turning it firmly to right to assure a perfect electric
contact.
- Connect TIG torch power cable to negative plug by turning it to right to assure a perfect
electric contact.
- Connect gas tube to gas bottle. Check the content of gas bottle, and replace it, if necessary.
- Adjust gas flow 6 l/min and 12 l/min according to the value of the current.
- Apply a tungsten electrode on TIG torch. The electrode must be sharpening according the
welding method: TIG DC (tip sharpen).
- Turn the main switch on rear panel to ON position.
- The Power ON indicator lights, indicating that machine is under voltage.
- Select LIFTIG* (TIG welding with contact ignition). There is the PULSED welding mode
available (both indicators are lit respectively).
For DC 224 (See items in Fig. 1 B)
Percentage increase in current value in relation to Ip (main current),
applied at ignition and start of welding.
Time elapsed since the start of welding in which the "Hot Start" value
must be valid.
/ I
Adjust the main current value.

p
To prevent the electrode from sticking to the workpiece during
welding, vary the Arc Force current amplitude in relation to the main
current. For values with a (-) sign, the Arc Force transition will be
rougher. For values with a (+) sign, the Arc Force transition will be
smoother.
Parameter
I
Adjust welding base current in percentage of main current.

WIDTH
Adjust width of the peak current (main.)
