Arc force
The arc force function determines how the current changes in response to variations in arc length
during welding. Use a low value of arc force to get a calm arc with little spatter and use a high value to
get a hot and digging arc. Turn main knob to adjust arc force level on a scale of 1 to 10 in arc force
screen. Confirm adjustment by pressing main knob and adjusted arc force level will be displayed in
menu screen.

TIG welding
TIG welding melts the metal of the workpiece, using an arc initiated from a
non-consuming tungsten electrode. The weld pool and electrode are protected by a
shielding gas that usually consists of an inert gas.
For TIG welding, the welding power source shall be supplemented with:
•
a TIG torch
•
a gas hose connected to the gas supply input (using a hose clamp)
•
an argon gas cylinder
•
an argon gas regulator
•
a tungsten electrode
•
a return cable (with clamp)
