LED INDICATOR "HOLD"
l
Permits subsequent checking of the welding parameters
l
Lights up after actual values have been stored (end of
welding)
l
The mean of the welding current and voltage values measu-
red before the end of a welding operation is indicated by the
digital displays and
l
The function works in the operating mode for r.c. pedal unit,
and pulsed-arc welding up to 20 Hz
Ways of deleting the HOLD function:
l
By actuating the torch trigger between welds
l
Switch the mains master switch off and back on again
l
By adjusting the welding current dial
between welding
l
By pressing the function button
l
Every time you start welding
LED INDICATOR FOR TIG PULSED-ARC WELDING
l
As soon as the TIG pulsed-arc remote-control unit TR 50mc
is connected up, the LED
headed "TIG pulsed-arc remote-control unit TR 50mc")
MAIN CURRENT DIAL I
H
l
For continuous adjustment of the welding current over the
2-140 A electrode or 2-160 A / 170A TIG range
l
LED indicator lights up (only at electrode operating mode)
l
The digital ammeter indicates the command value for current
as soon as the machine is in open circuit, and then switches
over to an indication of the actual value.
Command value ð desired welding current
ð actual welding current
Actual value
CRATER-FILL CURRENT: I
l
Only possible in 4-step operation
l
Is set as a %-age of the main current
When the crater-fill current potentiometer is used, the pre-
set value will be indicated for 3 seconds
l
The welding current is lowered to the crater-fill current when
the torch trigger is pressed.
l
LED control light indicates that this is taking place
The following parameters are laid down
l
Gas pre-flow time .......................................... 0,4 sec.
l
Start arc ......................................................... 29% of I
l
Up-slope ........................................................ 1,0 sec.
l
Gas post-flow time ......................................... 5-15 sec.
All parameters can be changed individually, via a program
menu.

TIG TORCH CONNECTION
l
for connecting the GAS + CURRENT supply for the welding
torch
SOCKET with bayonet coupling
l
as the earth cable connection point with TIG welding;
l
as the connection either for the manual electrode cable or
the earth cable with manual electrode welding, depending
on the type of electrode used.
TORCH CONTROL SOCKET
l
Plug in the control plug for the welding torch, and latch in
place.
SOCKET with bayonet coupling
l
only for welding torch central connection GWZ
l
as the connection either for the manual electrode cable or
the earth cable with manual electrode welding, depending
on the type of electrode used.

GAS CONNECTION
l
Screw the terminal nut of the gas hose onto the connection-
fitting and tighten it
MAINS CABLE WITH STRAIN-RELIEF GRIP
CONNECTING SOCKET for remote control unit
l
Plug the remote control cable plug into the socket, the right
way round, and tighten the swivel nut
l
The desired welding current is set on the remote control unit.
l
The machine automatically recognizes the fact that the
remote control unit has been plugged in
H
l
The short-circuit-proof supply voltage to the remote control
units protects the electronics in the event of any damage to
the remote control cable.
