The following parameters can be set within given ranges:
• Is[A] - welding current in amperes adjustable in the range of 5-150A 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
•
Tpunkt[s] - duration of spot welding in seconds adjustable in the range
0.01 - 10s with a resolution of 0.01s
•
Tg[s] - time of gas flow after the arc extinction in seconds, adjustable in
the range 1-25s with the resolution of 1s
You can select the method of ignition using HF button (4):
CONTACT IGNITION - LAMP (9) 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 (9) 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.
Following the arc ignition the welding current increases during the set
rise time Tn from minimum value (5A) to the set value of spot welding
current Is. The current Is flows during the set time Tpunkt and then
automatically starts the process of decreasing the welding current from
the Is value to the minimum value (during the set time To). 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. When the gas flows (after extinction of the
arc), it is possible to initiate the next spot welding process.
