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
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
J14: [Off ] limit of short press of the TIG switch is 0.7 s
[On] limit of short press of the TIG switch is 0.3 s
J15: [Off ] AC TIG welding is started in the positive half-cycle
[On] AC TIG welding is started in the negative half-cycle
J16: 0 -> 2.0 ratio for the start length of DC in AC TIG
J17: 0 -> 2.0 ratio for MMA ignition pulse
J18: ---------- vacant
J19: ---------- vacant
