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.
20. 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.
To prevent damage to the machine the temperature around the machine is controlled.
If this temperature is below -10°C or above + 40°C, the following text appear on the display and the machine can
not be started:
t°C - int – ‚measured temperature value’
Only when the temperature is in the prescribed range, the welding operation can be started.
