• Ik[%] - final current adjustable as a percentage of the welding current Is
within the range 5-50% with a resolution of 1%.
• 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 (and releasing) 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
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.
The arc ignites with the current Ip. Pressing again (and releasing) the
control button starts the process of increasing the welding current from the
Ip value to the set welding current Is (during the time Tn). Pressing (and
releasing) the control button once again starts the process of decreasing
the welding current from the Is value to the Ik value (during the set time
To). The last fourth pressing (and releasing) the control button causes the
arc extinguish. If the control button is pressed briefly during the current fall
phase, welding current will increase to the Is value again. Shielding gas
flows still during the set time Tg, then the gas valve is being closed. The
welding process has been completed.
4) REMOTE CONTROL WHILE TIG 2T AND 4T WELDING
If the TIG welding torch is equipped with 2 buttons, it is possible to change
the welding current during performing the weld. One of the buttons is for
increasing and the second for decreasing of current setting (you can freely
assign buttons). Holding down one of these buttons changes the welding
current during welding. Changes of welding current are reflected on the
welder display (1). The welding current could be changed by 1A within the
range from 5 to 50A, and within the range 50-200A by 5A. The change of
welding current made during welding is stored and the next cycle of
welding will be done using the new settings.
