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: 13kVA (unit) + 30% = 17kVA. 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.
