GENERAL EQUIPMENT SAFETY
The welding process can be dangerous if the correct safety procedures are not followed. It is important that anyone operating this equipment is
fully-trained and wearing the appropriate personal protection equipment. Please read these instructions carefully and store them in a safe place for
future reference.
ARC Rays can injure eyes and cause burns:
• Always wear a helmet with full face and neck protection with shade #10 Lens.
• Ensure that you use the appropriate eye, ear and body protection equipment.
• Do not touch work piece & welding wire at the same time.
• Use only the cables and rods recommended by the manufacturer.
• Always disconnect from the mains before carrying out any service or maintenance on this equipment.
Fire Hazards:
• Remove all flammable materials from within 35ft of the welding arc.
• Never carry out welding near pets or small children.
• Ensure that a fire extinguisher is available when welding.
• Wear oil free garments without pockets or cuffs.
• Do not weld on closed containers.
Toxic Fumes and Gases:
• Do not breathe fumes emitted by the welding process.
• Wear appropriate breathing apparatus.
• Ensure that you are working in a well-ventilated environment and that there is suitable exhaust at the arc.
• Do not cut coated, galvanised or plated materials (for example zinc, cadmium, mercury , barium) to avoid the risk of poisoning.
• Use a ventilator when necessary.
• Always refer to the MSDS for all welding materials used.
Magnetic Fields:
• Keep people with pacemakers away from the area when the welder is in use.
FIRST USE / SET UP
1.
Make sure the air intake is clean and clear to ensure the cooling system can operate at optimum performance levels.
2.
Ensure that the housing is earthed using cable not less than 4mm².
3.
Connect the electrode holder and earth clamp.
4.
Check that the polarity is correct for the welding process to ensure safety, a stable arc and avoid weld spatter.
5.
Check that the power supply is compatible with welder specifications and that all cables and plugs are correct and free from damage.
When using extension cables ensure that the length of cable is sufficient to carry the required voltage as any voltage drop will deplete safety and
performance not wrap the cable around any part of your body while welding.
Personal Protection Equipment:
• Anyone in the general area of the welding process should wear ear defenders to protect hearing.
• Wear approved safety glasses with side shields under your welding helmet or face shield and at all times in the work area.
