•
Adjust the air supply valve until the air pressure is up to the cutting torch
requirement. (Lowest pressure should be no less than 50PSI), the Low
Pressure Indicator Light will not be lit up in those conditions.
•
Adjust the air flow to be sure it is consistent.
•
Pull the torch trigger. The cutting operation begins after the cutting
plasma pilot arc is made.
Metal Sheet Cutting
•
Put the torch's nozzle at the start of the work piece. Turn on the torch
switch to ignite the plasma pilot. After the work piece is cut thorough,
move the torch along the cutting direction uniformly. The cutting speed
is determined by watching to see if the cutting goes all the way through.
If the speed is too fast, the work piece won't be cut thorough, or if too
slow, the cut quality would be affected, excessive warping may occur, or
the arc could stop.
•
When you've completed the cutting process, turn off the torch; the
plasma pilot arc will stop.
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.
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.
•
For thin materials reduce the amperage setting to get the best cutting
quality, reduce excessive warping and to extend the life of the electrode
and nozzle.
•
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 40-90psi. 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.
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.
