GENERAL CUTTING INFORMATION
Before starting any welding or cutting activity ensure that you have suitable eye protection and
protective clothing. Also take the necessary steps to protect any persons within the welding
area.
Notes for cutting operation
1. Do not touch the hot work piece with bare hands to avoid burning.
2. 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.
3. It is recommended to initiate the cutting from the edge of the workpiece unless penetration is
needed.
4. Ensure spatter comes from the bottom of work piece while cutting. If spatter comes upwards from the
top of work piece, it indicates that the work piece has not been fully cut through. This could be due to
not enough power or the cutting torch is moved too fast.
5. For cutting a round work piece or to meet precise cutting requirement, a stencil board or other tools
are needed.
6. It is recommended to pull the cutting torch while cutting.
7. Keep the nozzle of the cutting torch upright over the work piece and check if the arc is moving with
the cutting line. Do not bend the cable too much, step on or press upon the cable to avoid restricting
the air flow. The cutting torch may be burned if the air flow is too low. Keep the cutting cable away
from sharp edges.
8. When the work piece is nearly cut off, slow down the cutting speed and release the torch trigger to
stop cutting.
9. Check the torch consumables frequently to prolong the life.
10. Always ensure the correct consumables are fitted in the torch. Incorrect items may cause damage to
the torch or machine.
11. It is recommended that a torch of maximum length of 6 metres is used. If the torch cable is too long,
the performance of this cutting machine such as arc ignition will possibly be affected due to the fact
that the inner resistance of the cable will reduce the output voltage.
Please Note:
Your air supply must be free of moisture, water, oil or any other contaminants. Excessive water or oil
may cause double arcing, excessive electrode/tip wear or even torch head failure. Contaminants will
also cause poor cut quality.
When starting the arc, ensure you keep the pilot arc time to a minimum to avoid excessive wear on
the cutting tip.
Do not overtighten the electrode when fitting a new set of consumables. Over tightening may cause
damage to the head thread, the tip not to seat correctly
Only use the supplied or recommended ’O’ ring lubricant or grease for your plasma torch head, using
the wrong lubricant which cannot withstand high temperatures could cause damage to the plasma
torch head.
