WARNING
ELECTRIC SHOCK CAN KILL! FIRE CAN KILL, INJURE, AND CAUSE PROPERTY
DAMAGE!
• To reduce the risk of electric shock and fire, connect only to properly grounded
and fused outlets.
• Never alter the AC power cord provided on the welder. Never alter an
extension cord or extension cord plugs.
EXTENSION CORD USE
For optimum welder performance, an extension cord should not be used unless absolutely necessary.
If necessary, care must be taken in selecting an extension cord appropriate for use with your specific
welder.
Select a properly grounded extension cord that will mate the AC power cord of the welder with the AC
power source receptacle directly, without the use of adapters. Make sure the extension cord is
properly wired and in good electrical condition.
For an extension cord not exceeding 25 feet in length, choose the same AWG wire size as that of the
power cord on the welder. Extension cord lengths longer than 25 feet will require heavier wire gauges
to compensate for voltage losses.
INSTALL COMPRESSED AIR SUPPLY
WARNING
GASES UNDER PRESSURE CAN EXPLODE AND INJURE OR KILL! To
reduce risk of death or injury from faulty compressed air equipment, read,
understand, and follow the safety instructions in this manual. In addition,
make certain that anyone else that uses this cutting equipment, or a
bystander in the cutting area, understands and follows the safety instructions
as well.
COMPRESSED AIR REQUIREMENTS
The compressed air specifications for the plasma cutter are provided in the SPECIFICATIONS
section. This cutter uses only compressed air. The compressed air is obtained from an external
compressed air source (not included) and must be clean, dry, and oil-free.
An air line filter with a drain trap is recommended for use with this plasma cutter. An air filter alone may
not be sufficient to capture all of the moisture and oil expelled by the compressor. If the compressed
air is still not dry enough (clean and oil free), install an after cooler (either air or water cooled), and a
condensate drain along with the filter and drain trap. The after cooler and condensate drain take out
80% of the water and oil, and by doing so, increase the life of consumables. In some situations, where
high humidity is present, the addition of a refrigerated dryer may be required to remove excess
moisture.
When you install the air filter and drain trap, make sure the trap is upstream from the filter. Having the
drain before the filter allows for moisture removal prior to filtration. If an after cooler and condensate
drain are required, the aftercooler receives the compressed air first, then the condensate drain, the
drain trap, and finally the air filter. If a refrigerated dryer is being installed, it should be placed between
the condensate drain and the drain trap.
DO NOT USE COMPRESSED GASES OTHER THAN AIR! Compressed gases such as Argon,
Hydrogen, or Nitrogen are not acceptable for use in cutting. USE ONLY COMPRESSED AIR!
CONNECT TO COMPRESSED AIR SOURCE
1. Obtain a proper adapter to match the inlet of the plasma cutter to your style of quick connect
air fitting.
2. Apply pipe sealant or one wrap of teflon tape to the threads of any fitting obtained in step 1.
3. Connect your compressed air line to the cutter.
