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 cung operaon
 Do not touch the hot workpiece with bare hands to avoid burning.
 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 iniate the cung from the edge of the workpiece unless penetraon is needed.
 Ensure spaer comes from the boom of workpiece while cung. If spaer comes upwards from the top of workpiece, it indicates that the
workpiece has not been fully cut through. This could be due to not enough power or the cung torch is moved too fast.
 For cung a round or shaped piece or to meet precise cung requirement, a stencil board or other tools are needed.
 It is recommended to pull the cung torch while cung.
 Keep the nozzle of the cung torch upright over the workpiece and check if the arc is moving with the cung line. Do not bend the cable too
much, step on or press upon the cable to avoid restricng the air ow. The cung torch may be burned if the air ow is too low. Keep the cung
cable away from sharp edges.
 When the workpiece is nearly cut o, slow down the cung speed and release the torch trigger to stop cung.
 Check the torch consumables frequently to prolong the life.
 Always ensure the correct consumables are ed in the torch. Incorrect items may cause damage to the torch or machine.
 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 cung machine
such as arc ignion will possibly be aected 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/p wear or even torch head failure. Contaminants will also cause poor cut quality.
• When starng the arc, ensure you keep the pilot arc me to a minimum to avoid excessive wear on the cung p.
• Do not overghten the electrode when ng a new set of consumables. Over ghtening may cause damage to the internal torch head thread
so that the cung p will not seat correctly.
• Only use the supplied or recommended ’O’ ring lubricant or grease for your plasma torch head, using the wrong lubricant that cannot
withstand high temperatures could cause damage to the plasma torch head.
