The welding process is initiated by pressing a control button on the grip.
When the button is pressed the gas valve is opened. Releasing the button
starts the ionizer - spark-over between an electrode and a workpiece
should initiate ignition of the arc. If ignition of the arc does not occur within
2.5s ionizer is turned off and ignition process must be repeated.
Following the arc ignition
the welding current increases during the set
rise time Tn from minimum value (5A) to the set value of Is. Short pressing
(and releasing) the control button starts the process of decreasing the
welding current from the Is value to the minimum value (during the set fall
time To). If the control button is pressed briefly during the current fall
phase, welding current will increase to the Is value again. When the current
reaches the minimum value, welding current is turned off and the arc is
extinguished. Shielding gas flows still during the set time Tg, then the gas
valve is being closed. The welding process has been completed.

The following parameters can be set within given ranges:
•
Is[A] - welding current in amperes adjustable in the range of 5-200A with a
resolution of 1A
•
Ip[%] - initial current adjustable as a percentage of the welding current Is
within the range 5-50% with a resolution of 1%.
•
Tn[s] - welding current rise time in seconds adjustable in the range 0.1-5s
with a resolution of 0.1s
•
To[s] - welding current fall time in seconds adjustable in the range 0.1-20s
with a resolution of 0.1s
•
Ib[%] - base current adjustable as a percentage of the welding current Is
within the range 10-100% with a resolution of 1%. If the value of the basic
current is set to 100%, the welding current will have a constant value equal
to the set value of Is. If the value of the basic current is different from
100%, we get pulsating current with the following parameters: welding
current value will alternate between two values - the base current Ib at the
TL time (see below) and the welding current Is at TH time (see below)
•
TH[s] - duration of current pulses of the value Is in seconds adjustable in
the range 0.01 - 1s with a resolution of 0.01s.
TH parameter is adjustable
only when the set value of the base current Ib is different from 100%
•
TL[s] - duration of current pulses of the value Ib in seconds adjustable in
the range 0.01 - 1s with a resolution of 0.01s.
TL parameter is adjustable
only when the set value of the base current Ib is different from 100%
