Opening the Unit
The cover of the product may be removed only by specialized staff of the
manufacturer or of a service shop properly trained and approved by it!
2.6
Extension Cables on the Worksite
To extend power cord length, use exclusively properly approved extension cables that are
labeled as such and have the following conductor sections.
up to 20 m: 1,5 mm² (2,5 mm² recommended); Typ H07RN-F
over 20 m: 2,5 mm² (4,0 mm² recommended); Typ H07RN-F
When using the extension cable, it has always to be rolled off completely and lie
fully extended!
2.7
Checking the Product for Damage
Before every use of the product, check safety features and possibly existing parts with minor
damage for proper function. Make sure that the push-on connection terminals work properly,
that contact is fully established, and that the contact surfaces are clean. All parts have to be
installed correctly and properly conform to all conditions in order for the product to function as
intended. Damaged safety features or functional parts should be properly repaired or replaced
by an approved service shop.

Data Interface Cover Cap
The dust cap for the interface has to cover the port during operation, in order to keep humidity
and contaminations away.

Power Supply Specifications
2.9.1
Mains Power Supply
Utility suppliers' wiring requirements, occupational safety rules, applicable standards, and
national codes have to be respected.
When using power distributions on the worksite, rules for the installation of
earth-leakage circuit breakers (RCD) have to be respected, and operation
requires an installed breaker.
Generator or mains power fuse protection should be 16 A (slow blow). The product has to be
protected against rain and humidity.
2.9.2
Generator Power Supply
The required nominal generator capacity as determined by the power supply requirement of
the largest fitting to be welded depends on the power supply specifications, the environment
conditions, and the generator type itself including its control/regulation characteristics.
Nominal output power for a generator 1 phase, 220 - 240 V, 50/60 Hz:
d 20 .............. d 160
d 160 .............. d 450
Start the generator first, then connect the welding unit. The idle voltage should be set to
approx. 240 volts. When turning the generator off, disconnect the welding unit first.
The working output power of the generator decreases by about 10% per 1,000 m of
altitude. During the welding process no other device connected to the same
generator should be operated.
