Page 4: Safety Precautions
Safety Precautions The equipment is designed for use by qualified personnel who have completed professional training and have obtained a qualification certificate as a welder. The operator shall have sufficient professional knowledge of welding, cutting and circuitry. The machine should be operated only after having read and fully understood all the safety precautions and warnings contained in this manual and those generally applicable to welding operations. -
Page 5: Warnings
Warnings Welding and cutting operations are specialised operations which present a certain degree of risk. Professional training, correct operating procedures and protective measures reduce the accident risk and damage to equipment. Personal Safety Protection Welding and cutting operations generate noise, bright light and high-temperature sparks which will cause harm to human hearing, eyes and skin unless personal protective measures are implemented and proper operational instructions are adhered to. - Page 6 Welding and cutting on sealed gas tanks will cause explosions. These operations are prohibited. Welding and cutting areas must be provided with adequate fire extinguishing equipment. Regular testing for efficiency of this equipment is compulsory as is training of staff in the use of the equipment. Once the welding/cutting operation is completed, check for any high temperature spark or metal which might cause a fire and immediately dispose of it.
- Page 7 possible and the following procedures are suggested: Welders and cutters with cardiac pacemaker implants should obtain medical advice on the effects of EMF on the implant. Welders should minimise the possibility of electromagnetic field damage through the following methods. Route the electrode and ground cables together and, where possible, secure them with tape.

Page 8: Packaging And Transportation
Gas cylinders should be kept away from extreme temperatures and fire sources. Scratching on cylinder walls with hard objects should be avoided. A flowmeter should be installed on the gas cylinder in use in accordance with the manufacturer's operating instructions. Quick-coupling connectors must not be used and gas hose fittings should be tested for leaks. -
