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/cutter. 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 is a special type of work, with a certain degree of danger. Professional training, correct operation and necessary protective measures can effectively avoid and reduce the damage and loss caused by machine accidents. 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... - Page 6 Care should be taken to avoid fire hazards from cracked floors and walls. 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.
- Page 7 However, it would be wise to limit exposure to EMF as far as 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. Users 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.

Gas check & cut selection button: When the 'AIR’ mode is selected, air is ejected from the torch head and it is determined automatically whether the air volume is sufficient to ensure a smooth cutting process. When restarting the machine, it is advisable to remove overnight condensation from the torch by blowing for approximately 30 seconds through the cutter handle in the 'TEST' position. -
