Before starting any plasma cutting activity ensure that you have suitable eye protection and protective
clothing. Also take the necessary steps to protect any people within the area.
1.
Check the connection of the work piece, earth cable, cutting torch, gas cylinder, regulator and hose.
Make sure they are firm and reliable. Do not attach earth cable to the portion that will fall away.

.
Verify that the input gas supply pressure is set to 72psi (5.0 bar).
3 .
Switch on the power source. Adjust the cutting current knob to desired setting.
4.
Place the tip of the torch at the edge of the work-piece and make sure the tip is vertical to the work
piece. When piercing, the tip should be at an angle away from the body. After the arc starts, slowly rotate
the torch to the upright position. This is to blow the melted metal away and is particularly important when
cutting thicker material. Make sure that the torch is pointed away from you and the people near you to
avoid any danger from sparks and hot metal.
Push the safety trigger at the side of the torch first,
then press the switch to start cutting.
CAUTION
Always hold the hand torch away from your body as a precaution against
accidental torch firing. Be aware of this hazard. Failure to do so can result in serious bodily
injury.
5.
Evenly move the torch in the desired direction, at a speed which will ensure good cut quality.
When using shielded consumables, drag the torch tip directly on the work piece.
6 .
Hold the torch lightly on the metal or just above the metal. Holding the torch firmly to the work-piece
can cause the shield to stick and makes smooth cutting difficult. Pulling the torch through the cut is
easier than pushing it.
7 .
When the cut is finished, release the torch switch to extinguish the arc.
8.
After completing an operation, turn off the gas valve. Finally, to shut down, turn off the power source
and the wall switch.
