2.2. Metal Mesh Cutting 

-Fix the work piece and connect the earth cable with the work piece. 

-Put the cutting nozzle onto the work piece, lift torch up slightly from the work piece and turn on the 

switch to cut. 

2.3. Notice while cutting 

- Unnecessary igniting of the pilot arc in the air will reduce the life-

span of the torch’s electrode and 

nozzle. 

- It is best to start cutting at the edge of the work piece, unless you are piercing the work piece. 

-  Keep  a  space  between  the  nozzle  and  the  work  piece.  Pressing  the  nozzle  on  the  work  piece 

could  cause  the  nozzle  to  stick,  reducing  the  smoothness  of  the  cutting  action  creating  an 

undesirable result. 

Keep the torch’s nozzle vertical against the work piece, and watch to be sure the arc is moving 

along the cutting line. 

- Do not rapidly switch the torch trigger on and off; this will damage the pilot arc system and work 

piece. 

The plasma cutter’s working air pressure range is 50-90psi. Notice: the internal pressure switch 

will shut off when the air pressure falls below 50psi. The switch only works when the pressure rises 

to 50psi or above. 

-  Every  4-8  hours,  check  the  air  filter  on  your  air  supply  and  remove  excess  moisture.  Too  much 

moisture in the cutter or torch may lead to operational trouble. 

 

Always unplug the power supply before checking for and removing moisture.

 

 

4. Safety Requirements 

- Never allow the torch to be aimed at any part of a body. 

- Make sure to wear protective glasses and gloves while operating. 

-  Work  only  in  well-ventilated  areas.  If  necessary,  use  exhaust/ventilation  fans  to  keep  fumes  or 

emissions away from the breathing zone. 

- Do not touch the work piece while cutting. 

- Do not cut a pipes, containers, or other materials that contain, or have ever contained, flammable 

or explosive materials. 

- Do not work underwater or in wet/moist environments. 

- Do not bend the torch cable sharply; this may damage the air hose. 

- Nobody other than the operator should be allowed to access the working area. 

- Always turn off the power supply prior to repairing or moving the machine. 

-  Always  turn  off  the  power  supply  prior  to  repairing  or  installing  any  spare  parts  (e.g.,  torch, 

electrode, nozzle, ground clamp, etc.). 

- Never allow a person with a cardiac pacemaker close to the working area without the permission 

of  a  doctor.  The  magnetic  field  produced  by  plasma  cutters  during  operation  can  disrupt 

pacemakers and similar devices. 

- Do not allow the ground cable to be pinched or damaged. If damaged, replace immediately. 

- Never clean the slag off the torch head by hitting it against a hard object.
