SECTION 3 – OPERATION OF EQUIPMENT
OPERATION METHOD
•
Turn on the power switch of the machine, the power indicator should illuminate.
•
Select proper working mode and proper function. There are two working modes available on the
machine panel: 2T and 4T. There are two functions available: normal cutting and metal mesh
cutting.
•
Place plasma torch close to the surface of the material to be cut, push the torch trigger on the
cutting torch and the machine will begin cutting.
•
Set cutting current according to the thickness of workpiece.
•
A sudden halt may occur when the yellow LED on the front panel turns ON, this indicates the
machine is on over-load status. It is unnecessary to restart the machine it will re-start once the
internal machine temperature drops. The yellow LED will go Off once the temperature drops and
the operator can resume cutting.
•
Air Pressure range has been internally adjusted to 80 PSI. If the input air pressure is less than 35
PSI, the pressure switch will detect the air pressure is not enough and it will SHUT OFF the machine
and FAULT LED on the front panel will turn ON.
•
The built-in fan is very important in enabling the machine to have effective cooling. The operator
should make sure that the louvers are not blocked. The minimum distance between the machine
and nearby objects should be 25 cm / 10 inches.
CUTTING TIPS
•
It is recommended not to ignite the arc in the air if not necessary for it will shorten the lifespan of
the electrode and nozzle of the torch.
•
It is recommended to initiate the cutting from the edge of workpiece, unless piercing is needed.
•
Ensure spatters / sparks fly from the bottom of workpiece while cutting. If spatters / sparks fly
from the top of workpiece, it indicates that the workpiece is not being fully cut: the cutting torch
is moved too fast, the cutting current is too low or the material thickness exceeds the cutting
rating of the machine.
•
For cutting round workpiece or to meet precise cutting requirement use a cutting template to
guide the torch.
•
It is recommended to pull the cutting torch while cutting not pushing it across the material.
•
The most suitable distance from nozzle to the workpiece should be approximately 2mm in order
to ensure a clean cut of the material.
CONNECTION OF THE PLASMA TORCH AND GROUND CABLE
•
Connection of cutting torch: Connect the center plug on the cutting torch to the center socket of
the power supply, and tighten It clockwise to avoid gas leakage.
