Note! Display shows terminal voltage of power source. Depending on length and copper cross-
section of welding cables as well as on that of MIG guns real arc voltage and display might
differ many volts from each other, see table below.

When you adjust welding dynamics, display shows adjustment value for welding dynamics
-9...0...9 and value is kept on display still for approx. 3 s after end of adjustment. After that
display returns to show voltage.
3.1.1. WELD DATA / GAS TEST
Retrieval of welding parameters to displays,
Use of WELD DATA switch retrieves to displays those welding parameters, wire
feed speed, welding current, welding voltage which were used when welding was
stopped last. Welding values are indicated in display for so long as you are using
the WELD DATA switch and are kept in memory until you press again the start
switch for gun.
Testing the gas flow
A short press on the switch starts the flow of the shielding gas. The shielding gas flows for
approximately 20 seconds, or until the switch is pressed again.
3.1.2. SELECTO operations, MC panel
SELECTO is the name for the operation in which you can store welding parameters for memory
channels for reutilization. You can store to memory five sets of MIG/MAG welding values.
Parameters which can be stored are wire feed speed, welding voltage and welding dynamics.
Stored values are kept in memory though power is switched off from unit.
Note! You cannot store MMA welding values and MIG 2-sequence/4-sequence selection.
In SELECTO operations are three different operating modes:
SELECTO OFF:
Normal MIG/MAG welding with independent adjustments for wire feed speed and voltage,
SELECTO functions are not in use.
SELECTO ON:
Welding with stored welding values, wire feed speed, welding voltage and welding dynamics.
Only channel selection, channels 1...5 from panel is operating. Channel is selected, depending
on position of control mode, either with CH switch on panel, remote control unit or with regula-
ting module RMT 10 of PMT or WS gun. You can change the channel also during welding.
Digital displays indicate values for wire feed speed and voltage which are stored on the channel
in question. Stored value for welding dynamics can be brought to display by turning a little the
adjustment potentiometer for welding dynamics.
SELECTO SET:
Search of welding data for storage. Welding data are stored for wished channel by using the
SAVE switch. Those values for wire feed speed, voltage and welding dynamics are stored,
which were set before using the SAVE switch.
