pressing the parameters switch button (4). It is indicated by blinking of the
LED indicating welding current Is. Press again the button (4) to return to
the operation with automatic open circuit voltage reduction.
When the welding machine is equipped with a remote control module, it is
possible to remotely change the welding current during performing the weld.

TIG 2T welding (2 Step trigger) -
the red light should indicate
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
•
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%
•
Tg[s] - time of gas flow after the arc extinction in seconds, adjustable in the
range 1-25s with the resolution of 1s
CONTACT IGNITION - LAMP (8) IS OFF
The welding process is initiated by pressing a control button on the grip.
When the button is pressed the gas valve is opened. After releasing the
button
(while welding don't hold the button pressed!)
you can ignite the
arc by touching the workpiece and slightly lifting an electrode
(the arc
ignition occurs at the moment of lifting an electrode).
NON-CONTACT IGNITION - LAMP (8) IS ON
