9. Digital welding current meter and parameter value display. Displays time or Amperes.
10. Thermal temperature indicator lamp.
Switching the machine on
When you switch the machine on, a green standby light is illuminated. The main power
switch indicator lamp is also on. If the machine overheats or the supply voltage is
too high or too low, the welding operation automatically switches off, and the yellow
thermal temperature indicator lamp is illuminated. The light switches off again when the
machine is ready for operation. Make sure that there is enough space around the machine
body to allow the air to freely circulate and flow into and out off the machine.
3.5.1. Welding current regulation and remote control
Welding current can be controlled using the digital encoder potentiometer on the control
panel, when PANEL is selected (item 7). If you want to regulate the current using a
remote control, first select and connect the remote control device and then select the
’remote control device type’ on the control panel button (item 7). See remote control
options – RTC10/RTC20/R10 and R11F. The remote foot pedal R11F can only be used
in 2T operation mode.
3.5.2. MMA welding settings
MMA welding is selected when the indicator lamp next to the MMA symbol is
illuminated. Press the process button to select the MMA process (item 4). The electrode
ignition time, the ignition pulse, and the arc dynamics are automatically adjusted.
3.5.3. TIG welding function
Select the TIG welding process by pressing the MMA/TIG button.
Standard 2T torch trigger control, and HF arc ignition.
The shielding gas starts to flow when the torch trigger is depressed and the welding arc
is established automatically via HF ignition. The current starts to rise, (if slope up time
is established) to the pre determined welding current level, and starts to drop (if slope
down time is established) when the trigger is released. The arc stops at the end of the
cycle and the post gas time elapses as set.
4T torch trigger latching, and HF arc ignition.
The shielding gas starts to flow when the torch trigger is pressed. The arc is automatically
established when the trigger is released via HF ignition. The current starts to rise (if
slope up time is established) to the pre determined welding current level. When ready
to end the welding cycle, press and release the torch switch again. The welding current
starts to drop (if slope down time is established) until the arc is extinguished and the post
