28. Maintenance and safety check
This unit should be serviced in regular intervals dependent on Operating times and working place conditions.
Before opening the machine switch off the plug!
- Clean unit inside by vacuum cleaner according to degree of soiling.
Attention:
This Welding unit has to be safety checked every year by Jäckle & Ess System GmbH Company or another
special qualified electrician according to the harmonized standard
IEC 60974 – 4
Safety, maintenance and inspection of arc welding equipment in use

Pin Name Description
A / 1 Actual volt-
age
(U-actual)
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
B / 2 Actual cur-
rent
(I-actual)
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
C / 3 GND Ground potential for Pin 1, 2, 4, 5
D / 4 Master (U)-
voltage 2
Input signal for the function of EC 2
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).
E / 5 Master (U)-
voltage 1
Input signal for the function of EC 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).
F / 6 +10V
+10V reference voltage output for potentiometer control Pin 4, 5
The maximum output current is 10mA.
G / 7 +24V +24V reference output voltage for the switch signals Pin 8, 9, 10
The maximum output current is 10mA
H / 8 T – BT MIG / TIG torch trigger input signal, supply to pin 7
Start signal for automation.
J / 9 T – up Input signal for an up / down torch, here the increasing (up) signal, supply to pin 7
K / 10 T – down Input signal for an up / down torch, here the decreasing (down) signal, supply to pin
7
L / 11 Current flow
Potential-free contact. If a current flow is detected, the contact is closed.
The contact opens when the current flow is interrupted.
Maximum voltage 48V, maximum current 1A
M / 12 Current flow
