Engine-driven generator recommendations
Generators used with the Powermax65 or Powermax85 should satisfy the following requirements:
CSA
• 1-phase, 50/60 Hz, 230/240 VAC
• 3-phase, 50/60 Hz, 200-600 VAC (480 VAC recommended for best performance)
CE
• 3-phase, 50/60 Hz, 380/400 VAC (400 VAC recommended for best performance)
Note: Based on the generator rating, age, and condition, adjust the cutting current as needed.
If a fault occurs while using a generator, turning the power switch quickly to OFF and then to ON again
(sometimes called a “quick reset”) may not clear the fault. Instead, turn OFF the power supply and wait 30 to
45 seconds before turning ON again.
