This light will illuminate when the power cord is connected to the mains supply and the power switch, on the rear of the unit, is in the ‘on’
position.

protection inDicator liGht fig.1.3
5.3.1.
When the unit is in ‘thermal overload’, is over voltage or lacking voltage, the indicator light will illuminate and the machine will stop
working. When the unit has cooled down and the voltage stabilises, the unit will return to operation automatically.

earth caBle connection fig.2.5
5.4.1.
The earth cable connects to the workpiece.

cUrrent aDJUstment fig.1.4
5.5.1.
Varies the output cutting current. Higher output is for thicker metal. maximum cutting thickness is 10mm for this unit. maximum cutting
thickness varies depending on the material being cut. Refer to Table, fig.3A.
5.6.
torch
5.6.1.
The torch comes fully assembled. Fig.3 below shows how the components are assembled.
6. operation
warninG!
never allow the torch to be aimed at any part of a body.
9
make sure to wear full PPe, refer to Safety section, while operating.
9
Work only in well-ventilated areas. If necessary, use exhaust/ventilation fans to keep
fumes or emissions away from the breathing zone.
8
Do not
touch the work piece while cutting.
6.1.
Check the unit to see if it has been connected correctly and is in good working condition.
6.2.
Follow all safety advice in Section 1 concerning electrical and General Safety.
6.3.
Switch on the unit and observe if operation is normal: the fan should start up and the
power indication light should be on.
6.4.
Pull the trigger: the cutting operation begins after the cutting plasma pilot arc is made.
6.5.
CUTTING fig.4
6.5.1.
metal sheet cutting
Connect the earth cable to the workpiece.
Put the torch’s nozzle at the start of the workpiece.
Turn on the torch switch to ignite the plasma pilot.
After the work piece is cut through move the torch along the cutting direction uniformly.
The cutting speed is determined by watching to see if the cut goes all the way through.
If the speed is too fast the workpiece will not be cut all the way through. If the speed is too slow, the quality of the cut will be affected,
excessive warping will occur or the arc could stop.
When finished turn off the torch, the plasma pilot arc will stop.
6.5.2.
metal mesh cutting
Fix the workpiece and connect the earth cable to the workpiece.
Put the cutting nozzle onto the workpiece, lift up the torch slightly and turn on the switch to cut.
6.5.3.
cutting action
Unnecessary igniting of the pilot arc in the air will reduce the life span of the torch’s electrode and nozzle.
Start at the edge of the workpiece unless you are piercing the work piece.
