1.0 Recommended Safety Guidelines Some safety precautions BOC recommends are as follows: Repair or replace defective cables immediately. Keep fire extinguishing equipment at a handy • • location in the shop. Never watch the arc except through • lenses of the correct shade. Keep primary terminals and live parts effectively •...
2.0 Recommended Safety Precautions Health Hazard Information Wear a respirator when natural or forced • ventilation is not good enough. The actual process of welding is one that Eye protection can cause a variety of hazards. All appropriate safety equipment should be worn at all times, i.e. A welding helmet with the appropriate welding headwear, respiratory, hand and body protection.
2.3 Cylinder Safety Cylinder Valve Safety When working with cylinders or operating Cylinder valve hand-wheel cylinder valves, ensure that you wear appropriate protective clothing – gloves, boots and safety Back-plug glasses. Bursting disc Ensure cylinder value is closed before moving or disconnecting equipment.
STOP 2.4 Electrical Shock Never touch ‘live’ electrical parts. • Always repair or replace worn or damaged parts. • Disconnect power source before performing any • PLEASE NOTE that under no circumstances should maintenance or service. any equipment or parts be altered or changed in Earth all work materials.
Switch on to electrical safety for single-phase equipment BOC welding machines are designed and manufactured to conform to IEC 60974 or AS 60974. This Standard not only covers the machine but also the input cable and plug requirements including the size of the plug that should be used.

DON‘T ✖ Don’t risk damage to your machine or cause tripping and/or fire by using the wrong input current, cable or plug. ✖ Don’t tamper with plugs or file down earth pins. Doing so will void warranty. Always Check the rating plate on your machine. All welding machines that comply with IEC 60974 or AS 60974 must have a rating plate similar to the ✓...

Metal-cored wires transfer metal in dip mode at weld pool to spill over, cannot normally be used low currents just like solid MIG/MAG wires. This for positional welding. The main exception is transfer mode is used for all positional work with aluminium and its alloys where, primarily because these types of wire.
