3.2.3 Symbols and their meanings
The symbols used on the control panel have the following meanings:
The cutting equipment is currently in 2-step cutting mode (see Section 3.2.4.1).
The cutting equipment is currently in 4-step cutting mode (see Section 3.2.4.2).
The cutting equipment is set to gas test. By pulling upwards and then turning
the blue adjustment knob, it is possible to set the required air pressure using
the pressure gauge (see Section 3.1.2).
Blue adjustment knob used to set the required air pressure. To do so, pull the
adjustment knob upwards and continue turning in this position until the
pressure displayed on the pressure gauge corresponds exactly to the required
air pressure (see Section 3.1.2).
Recommended range of adjustment on the current scale, using an electrode
diameter of 1.4 mm (the symbol is modified appropriately with other sizes).
Current scale for torches R145 and R145P (see Section 4.3.2.2, “Machine
configuration”).
Current scale for torch A80 (see Section 4.3.1.2, “Machine configuration”).
Wear and tear on the torch parts is displayed as follows:
Flashing: Early warning of increased level of wear and tear. It is
recommended that the wear parts are changed.
Continuous: Wear has exceeded permitted limits. Equipment will shut down.
The point in time at which the wear parts are changed is determined by the user.
There is a voltage at the torch. The pilot current is active, or following ignition of
the cutting arc the set cutting current is flowing.
The air pressure is no longer sufficient to supply the torch.
Equipment will shut down.
The cutting equipment has shut down due to excessive temperature. After it
has cooled down, the cutting equipment automatically reverts to operating
mode.
When heavily loaded, especially when cutting work takes place in a hot
environment, the overtemperature protection can switch off the welding current.
This is indicated by the control lamp.
Power supply voltage switch is switched on, power supply voltage is on (only
with RTC 60).
