Wire conveying inside the torch hose pack
Friction resistance of the welding wire inside the wire guide spiral increases in proportion to the length of the hose
pack. Therefore, the torch hose pack shouldn't be any longer than necessary.
When working with aluminium welding wire, it is advised to replace the wire guide spiral with a Teflon wire guide
core. Length of torch hose pack should not exceed 3 m.
After finishing one coil of wire, it is advised to clean both the wire guide spiral and the wire guide tube by air-
blasting.
The gliding quality of the wire guide spiral deteriorates according to the amount of wire conveyed and the
properties of the wire. If wire conveyance becomes unacceptably worse, change the wire guide spiral.

36. Over temperature
When the machine is getting hot during welding, it switched off and it can not be welded, until the machine is
cooled.
In over temperature conditions the following text appears in the displays:
t°C = hot = temperature to high
01 = not used, 02 = Thyristor, 03 = Welding transformer / Choke
Operating manual
Description
Output signal between 0V and +10 V.
The ratio between welding voltage and signal voltage is 10:1.
Example: 40V welding voltage = 4.0V signal voltage
Input impedance should be ≥ 10k. The reference potential is pin 3
Output signal between 0V and +10 V.
The ratio between welding current and signal voltage is 100:1.
Example: 100A welding current = 1V signal voltage
Input impedance should be ≥ 10k. The reference potential is Pin 3
Ground potential for Pin 1, 2, 4, 5
Input signal for the function of EC 1 (only MC 1).
1) To contact a potentiometer (between pin 3 (0V) and pin 6 (+10 V)).
The output of the potentiometer changes this value.
2) Similarly, a control voltage between 0 V and a maximum of +10 V can be applied
(reference point Pin 3).
Input signal for the function of EC 2 (only MC 1).
1) To contact a potentiometer (between pin 3 (0V) and pin 6 (+10 V)).
The output of the potentiometer changes this value.
2) Similarly, a control voltage between 0 V and a maximum of +10 V can be applied
(reference point Pin 3).
+10V reference voltage output for potentiometer control Pin 4, 5
The maximum output current is 10mA.
+24V reference output voltage for the switch signals Pin 8, 9, 10
The maximum output current is 10mA
