7. EXTRA FUNCTIONS
There are extra functions and selections in the machine, which are not seen in the panel. The welder
needs these functions not in normal welding, but they may be a solution in some special cases.
These function are called jumper functions, because they are behind jumper numbers. Function can
be On/Off -type or adjustable parameter.
Jumper functions
1. Turn off the machine.
2. Press the [POST GAS] button and at the same time turn the machine on.
You can see text (J01 OFF) or (J01 ON) on the panel.
3. Choose jumper number you need by pressing the [REMOTE] button.
4. Change jumper setting with the pulse potentiometer.
5. When you have done the changes needed press the [POST GAS] button. All jumper settings are
then saved in the memory.
Factory settings are underlined.
J01: [On] = slope of up slope is constant, time depends on set value of current.
[Off] = up slope time is independent of set value of current.
J02: [On] = slope of down slope is constant, time depends on set value of current.
[Off] = down slope time is independent of set value of current.
J03: [On] = TIG antifreeze is on.
[Off] = TIG antifreeze is not in use.
J04: [On] = manual AC balance control.
[Off] = balance function in use.
J05: [On] = tag welding automatics is not in use.
[Off] = tag welding automatics on.
J06: [On] = down slope of TIG is minimum end level current.
[Off] = end level current is 20 % of the welding current
J07: [Off] = open-circuit voltage is 70 V
[On] = open-circuit voltage is 12 V without VRD card, 22 V with VRD card
J08: [On] = when stopping welding with 4T function the down slope starts by pressing torch
connector. Slope continues as long as you press the connector. Current stays at
end level in case you press longer than down slope´s normal time (look J06).
[Off] = normal 4T function.
J09: [Off] = primary frequency is 18 kHz / 36 kHz (depending on the set value)
[On] = primary frequency is 18 kHz in the whole current range.
J10: [Off] = hot/soft - start function is not in use on 2T function.
[On] = hot/soft - start function is in use on 2T function.
J11: hot/soft - start time adjustment on 2T function (0.0 … 9.9 s). J10 has to be in position [On]
J12: [Off] = on 2T function the down slope is cut off by a short press of the switch
[On] = on 2T function the down slope does not cut off by a short press of the switch
J13: [Off] = on TIG AC the level of positive half-cycle changes when the balance and set value
change (both with auto and manual balance)
[On] = on TIG AC the level of positive half-cycle is always the same as the level of the
negative half-cycle
