Direct current (DC) with HF-ignition
(contactless ignition)
• Locate torch with electrode over the place where the start of the weld is desired.
• Press the torch button.
• Arc is ignited.
• Welding current rises to the preset rate.
To finish the weld, release the torch button.
Welding current drops to the preset drop-off current.
Square AC with HF ignition
• Highest effectiveness, through stable arc.
• For light metals such as aluminium.
Sinusoidal AC with HF ignition
• High effectiveness.
• Lower noise than square AC.
5.4 REMOTE CONTROL
LED foot operated remote control
This LED indicates, that a foot operated remote control is connected to control the set value of the
welding current.
The device changes automatically to two-stroke-mode and disconnects the slope functions.
Using the foot operated remote control, the maximum available welding current is set using the
potentiometer I2 (27).
LED hand operated remote control (current selection external)
This LED (3) illuminates, if an external device (foot or hand operated remote control) is connected
and the welding current is determined by that control.
The maximum available welding current is set using the potentiometer I2 (27).
The Up-Slope (9) and Down-Slope (14) have to be set by connection of a hand operated remote
control.
