22. JOB Menu

It is possible to save up to 100 different welding settings as JOBs.
Store JOB:
Adjust the machine optimally for the welding job.
Press key JOB (item 12) until the upper display shows '1'.
Now select a disk space with rotating the knob (item 8).
An occupied disk space is indicated by the word 'USd', for a free memory the word 'FrE'.
To store the JOB, press key ‚SAVE' (item 11) until '===' appears in the lower display.
Now the JOB is stored.
Recall JOB:
To call a stored JOB, Press key JOB (item 12) until the upper display shows '1'.
Now, using the knob (item 8) select the job you want to select.
To load the JOB, tap on the key JOB again.
The display shows '===' appears in the lower display. The job is no loaded into the machine.
The following symbols are used: 'USd' = memory used

23. Gas test / Water test - Coolant flow rate display

Function Gas test:
By long pressing (> 1 s) the key ,JOB ' (Pos. 12), the solenoid valve will open to flood the pipes with gas.
Tapping again on the button ,JOB', the solenoid valve will be closed again.
Function Water test:
By long pressing (> 1 s) the key ‚SAVE' (Pos. 11), the water pump is activated.
Hereby the water circuit can be filled.
Additionally the upper display (Pos. 1) shows ,H2o' for water and the lower display shows the current coolant
flow rate, for example, 1,45l / min.
The water pump will stop automatically after 1 minute.

24. VRD Function (Voltage reduction for electrode)

The VRD function is only used in the welding process ELECTRODE.
"Voltage Reduction Device" (VRD) is a protection device, to set the open-circuit voltage lower than 13V.
It prevents the formation of voltages at the output terminals, which can be dangerous for people. As standard
this feature is disabled, and is not required for normal welding operation.
Two-colour display LED VRD:
OFF: VRD not active
Green: VRD active, voltage OK
Red: VRD active, machine is in weld mode and the VRD protection is deactivated
