Instruction Notes
1. Operating environment
1.1
The machine can be operated in harsh weather conditions at temperatures of
between -10 and +40 Degrees Centigrade and a Relative Humidity of 80%.
1.2
Do not place the machine in direct sunlight or operate it in the rain.
1.3
Keep the machine dry and avoid any contact with water.
1.4
Do not use the machine in a dusty atmosphere or one containing a corrosive or
explosive gas.
1.5
If the machine will not be used for a long period of time it should be returned to its
original packing box and stored in a dry environment.
1.6
The machine has an internal fan to cool the high power electronics and the entry
and exit ventilators must not be obstructed. Ensure there is sufficient space in front
and behind the machine for the forced air to circulate.
1.7
Ensure the power cable is connected to a supply which has the correct voltage and
current rating. The machine has a built in electronic control to adjust for different
mains voltage over a limited range. There is a label on the back of the machine
indicating the machine setting. Units supplied to the UK will be set for 220Vac
(190-255Vac) which is suitable for single phase supplies.
The machine will be seriously damaged if it is connected to a 415V Three
Phase supply.
1.8
Always stand the machine on a level surface to prevent the unit overturning.
2. OPERATING SAFETY
2.1
Ensure the working area is adequately ventilated and clear of all flammable
materials.
2.2
When operating in MMA Mode, the electrode is energised as soon as the mains
power is turned on; there is no welding current on / off switch. In TIG Mode
welding is controlled by the torch switch or foot pedal.
2.3
Always turn the machine power off when the welding operation is completed.
2.4
When using the machine on site or outside ensure the grounding terminal on the
back of the machine is connected to a safety earth. This will prevent any leakage
current from the welding circuit causing an electric shock to the operator. A cable
with a cross sectional area of 6mm2 is suitable for this purpose. The electrode
holder and work clamp are not directly connected to the mains earth inside the
unit although the unit case is earthed to the mains cable protective conductor
(earth wire)
2.5
Do not weld any containers or pipes which have held or contain gaseous or liquid
