Authorized for welding under increased electrical hazard
Manufactured in accordance with EN 60 974-1 and EN 60 974-10
Generator operation:
The generator must have 30% more power as the welding unit.
Example: 11kVA (unit) + 30% = 15kVA. The generator for this unit must have 17kVA.
A generator with less power will damage the Jäckle welding unit as well as the generator himself
and is disallowed.
13. Environmental conditions
The power source must be operated at a temperature between -10°C to +40°C and a relative humidity of 50% at
40°C or up to 90% at +20°C. The ambient air must be free of unusual amounts of dust, acids, corrosive gases or
substances, etc., unless they occur during welding.
