generator recommendations

Generators used with the Powermax45 should satisfy the following requirements:
CSA
• 1-phase, 50/60 Hz, 230/240 VAC
• 3-phase, 50/60 Hz, 480 VAC
Ce
• 1-phase, 50/60 Hz, 230 VAC
• 3-phase, 50/60 Hz, 380/400 VAC (400 VAC recommended for best performance)

(CSA/Ce)
8 KW 33 A
6 KW 25 A
Notes: 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 the power supply off and wait 30 to
45 seconds before turning it on again.

Prepare the gas supply

The gas supply for the Powermax45 can be shop-compressed or cylinder-compressed. A high-pressure regulator must
be used on either type of supply and must be capable of delivering gas to the filter on the power supply at
6.2 bar (360 scfh at 90 psi).
do not allow the gas supply pressure to exceed 9.3 bar (135 psi). The filter bowl may explode if this
pressure is exceeded.
If gas supply quality is poor, cut speeds decrease, cut quality deteriorates, cutting thickness capability decreases, and
the life for consumables shortens. For optimum performance, the gas should have a maximum particle size of 0.1 micron
at a maximum concentration of 0.1 mg/m
0.1 mg/m (per ISO 8573-1 Class 1.2.2).
