9.  Bring  the  Electrode  (4A)  of  the  Torch  close  to  the  starting  point  of  the  cut.  The 

Working Indicator Light will come on. 

10. Slowly move the Torch at a slight angle along the cutting line with the Torch tip trailing. 

The air causes the molten metal to fall away from the work piece being cut. If proper 
cutting is not achieved, adjust the Power Supply Controller to a higher level, and/or 
increase air flow. To increase air flow, press the Power Switch to the Off (O) position, 
then adjust the air pressure at the Air Pressure Regulator. The air will continue for a 
few seconds once the trigger is released. 

Note:

 If too much current is drawn from the Plasma Cutter (i.e., short circuit), the Thermal 

Switchman overload protector, will activate and the red Thermal Overload Indicator Light 
will light. The Plasma Cutter will turn off until it cools down. To reset you must turn the 
power OFF then back ON. Press the Trigger to begin cutting again. 
 

11. When finished cutting: 

a.  Release the Torch handle trigger and lift the Torch handle from the work piece, 
b.  Press the Power Switch to the Off (O) position. 
c.  Set the Torch handle down on the metal workbench, 
d.  Turn the air supply off, 
e.  Unplug the line cord from the electrical outlet. 

Plasma Cutting Technique 

      Using a plasma cutter is a skill that requires time and effort to do well. Practice striking 
and  maintaining  an  arc  on  scrap  work  pieces  before beginning  work.  This  will  help  you 
gauge the best settings for the plasma cutter for the material at hand. 
 
1.  You can cut metal that will conduct electricity up to approximately 1/2” thick mild steel 

or equivalent. Very thin or very thick metals are more difficult to cut cleanly. 

2.  Generally  set  the  air  pressure  between  60  and  80  psi.  Increased  air  pressure  will 

increase plasma speed and cutting pressure. Air pressure and amperage should be 
adjusted in tandem. 

3.  Generally  start  with  a  mid-range  amperage  setting  (32-33  amps)  and  adjust  up  or 

down from there. Increased amperage will increase cutting heat. This is needed with 
heavier and harder metals. However, increased amperage will reduce Duty Cycle time. 
(See page 8.) 

4.  Move the cutting head more slowly for thicker and harder metals, and more quickly for 

thin or soft metals. Keep the cutting head moving while cutting. 

 

How do Plasma Cutters Work? 
   

  Plasma  cutters  work  by  feeding  an  inert  gas  (air)  through  an  electric  arc.  The  air  is 

then  heated  to  an  extremely  high  temperature  which  converts  the  gas  to  plasma  which 
cuts the metal. 
      High  temperature  and  pressure  are  required  to  create  a  plasma.  The  electric  arc 
provides  the  temperature,  and  by  exhausting  the  air  through  a  very  small  orifice,  the 
pressure is increased far beyond the 60-80 PSI operating pressure of the air supply.
