– 2T – (2-stroke mode)
Please choose the 2-stroke mode with the switch on the front panel (position 1). Pressing
and holding the torch switch starts the unit to weld on. To stop the welding process, please
release the torch switch.
8.3
– 4T – (4-stroke mode)
Please choose the 4-stroke mode with the switch on the front panel (position 2). Pressing
and releasing the torch switch starts the unit to weld on. To stop the welding process, please
press and release the torch switch again.
8.4 Spot-welding
Would you like to weld short seams, you have to activate the switch on the potentiometer, by
which the spot welding time (between 0.5
– 2.5 seconds) can be adjusted. The other welding
parameters are set like in chapter 6 and 7 in this manual. The existing gas nozzle must be
exchanged by a gas nozzle for spot welding. By pressing the torch switch, the unit starts to
weld. If the set spot welding time has elapsed, the device switches off automatically. The
next weld seam can be generated by the re-releasing and pressing the torch switch.
8.5 Interval-welding
Would you like to weld several seams one after another, you have to activate the switch on
the potentiometer and adjust the spot welding time (between 0.2 - 2.5 seconds), the time of
the desired intervals (between 0.2 - 2.5 seconds) and the speed of the wire. By pressing the
torch switch the unit starts to weld on. During the adjusted interval periods, the shielding gas
and the contactor are still active. The feed motor turns off. Please press the torch switch
during the whole welding process.
8.6 Softstart
With a sufficient wire speed (min.0, 5 m/min) the softstart switches on automatically.
