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.
