Install and Set Up the Plasma Power Supply
56 810470 Operator Manual Powermax65/85/105 SYNC
Use shop-compressed gas or cylinder-compressed gas.
Use a high-pressure regulator on either type of gas supply. The regulator must be able
to deliver gas to the air inlet on the plasma power supply at the specified flow rate and
specified pressure.
Use only clean, moisture-free gas.
Oil, water, vapor, and other contaminants in the gas supply can cause damage to
internal components over time.
Poor gas supply quality causes:
Decreased cut quality and cut speeds
Decreased cut thickness capability
Decreased consumable life
To address these problems, use an optional air filtration system. Refer to Add additional
gas filtration (if necessary) on page 60.
High-pressure gas cylinders
WARNING
GAS CYLINDERS CAN EXPLODE IF DAMAGED
Gas cylinders contain gas under high pressure. If damaged, a cylinder can explode.
For high pressure regulators, comply with the manufacturer’s guidelines for safe
installation, operation, and maintenance.
Before plasma cutting with compressed gas, read the safety instructions in the Safety and
Compliance Manual (80669C). Failure to comply with safety instructions can cause
personal injury or equipment damage.
WARNING
EXPLOSION HAZARD – CUTTING WITH FLAMMABLE OR OXIDIZING GASES
Do not use flammable or oxidizing gases with Powermax systems. These gases can cause
explosive conditions during plasma cutting operations.
An example of an oxidizing gas is oxygen. Examples of flammable gases are acetylene,
propylene, methane, and pure hydrogen. Refer to the Safety and Compliance Manual
(80669C) for more information.
