3. GENERAL DESCRIPTION
DIGITIG 206 p AC/DC is used for manual welding with coated electrodes structural steels AC
and (MMA) and steel and non-ferrous metals established electrode in inert gas (TIG). In the design
and construction of the device uses the latest advances in technology, PWM (pulse width modulation)
and IGBT modules (with bipolar transistors insulated-gate), which resulted in that the welder is
characterized by small size and low weight.
DIGITIG 206 p AC/DC has a static arc. Has the functions of ARC FORCE, build-up and
downslope, pre flow and post flow gas and adjustable pulse parameters. The device is also equipped
with intelligent security overload, overvoltage and thermal. If you have previously described event
alarm LED indicator lights on the front panel and the disabled will be output. This leads to the self
security of the device and to extend its service life.
Function ARC FORCE
ARC FORCE function allows you to adjust the dynamic range of the welding arc. The shortening of
the length of the arc is accompanied by an increase in welding current, resulting in stabilizing the
arc. Decreasing the value will give you soft arc and less depth of penetration, while increasing the
value causes a deeper penetration and the possibility of submerged arc welding. With large values of
the ARC FORCE can be welded together by keeping the bow with a minimum length and high speed
melting electrode
MMA-welding coated electrode (Manual Metal Arc welding);
PWM-pulse width modulation (Pulse-Width Modulation);
IGBT — bipolar with insulated-gate (Insulation Gate Bipolar Transistor)
TIG-welding of tungsten electrode in argon (Tungsten Insert Gas welding)
