6 OPERATION

Glycol

The cooling unit contains poisonous glycol which must not be drunk or poured down

the drain or into the soil or water. Regularly top up the tank to a level 1 cm below the

top if water is lost during hose changes.

Avoid using glycol if the conditions are not cold enough to warrant it.

Pure water gives the best cooling effect.

6.1 Flow monitor

Applies to OCF 2M and options.

The flow monitor is connected in series with

the thermal cut--out inside the power source.

If the water flow is restricted or stopped this

will trigger the flow monitor and prevent

further welding.
