LED illuminates when voltage is applied to the welding current socket.
In the TIG operation mode, after activating the torch button whereas in
the electrode operation mode, this occurs after selecting electrode
welding.
LED illuminates when the solenoid valve is open and the protective
gas can flow. After switching the device on, the hose bundle is
automatically purged with protective gas.
LED lights in the ramp up phase (Up-Slope).
Sets the rate at which the current ramps up from the ignition current I1
to the welding current I2. Turning direction anticlockwise decreases
the ramp rate.
Displays the value of the welding current of the current function.
Sets the current I4 during pulsed operation.
I4 active. During pulsed operation: Toggles between the two displays
I4 and I2 with fixed pulse frequency.
Displays the ramp down phase (Down-Slope).
Sets the rate at which the welding current I2 ramps down to the
drop-off current I3 at the end of throat. The ramp down prevents
cratering.
In order to manually purge the hose bundle with protective gas.
Pressing this button opens the gas valve without applying a welding
voltage to the electrode.
During pulsed operation: When activating the button gas test, the
display (10) switches to the I4 value.
Display of possible error messages.
LED flashes if a fault condition occurs in the device. The error
message appears in the error display.
Sets the gas post-flow time after finishing welding to protect the
weldpool. The time can be set from approximately 0.2 to 30s.
Continuous setting of the AC frequency from 50 Hz up to 200 Hz.
LED illuminates when the final current I3 is active.
If the rotary switch is set to the middle position, the positive and the
negative half cycles are equal for AC welding.
This rotary switch is deactivated, when welding using DC current (DC
operation).
• DC with lift arc ignition
• DC with HF ignition
• Square AC with HF ignition
• Sinusoidal AC with HF ignition
LED illuminates, when the ignition current I1 is active.
