If you have purchased a Liquid-Cooled variant, the water connections are industry standard and are marked blue (showing the cold
water inlet) and red (showing the hot water outlet)
The water inlet and outlet hoses should be connected to the relevant machine fittings.
We recommend a good quality water coolant additive is added to the cooling fluid, this will enhance cooling through the torch body
and will prolong torch hose life. It will also prevent frost damage to the torch internal components.
When first connecting a Liquid-Cooled variant, run the cooler before you weld to remove any trapped air pockets and remember to
check the water levels in the cooler after this startup check. An average 8m torch will hold around 0.5 liters of coolant. After welding,
we recommend that you run the water cooler for at least one minute to cool all the torch’s internal components. When removing a
Liquid-Cooled torch from a recirculator and to prevent loss of coolant from the torch, use the red and blue stoppers that are supplied.
We recommend draining the torch of coolant if it is not going to be used for any length of time.
You will require a water cooler (recirculator) with the following specification:
• Minimum water flow : 1.2 l/m
• Minimum inlet pressure :2.0 bar
• Minimum cooling capacity :1600W
• Maximum inlet pressure 5.0 bar
• Maximum water inlet temperature 50
o
C
We strongly recommend that a flow switch be fitted to the return side of the recirculator and wired in series with the torch trigger. This
flow switch will shut down the system and give torch protection should the water flow rate drop below 1.2 Litres per minute. (72 Litres
per hour)
Liquid-Cooled neck assemblies
Liquid-Cooled Torch necks are supplied with a location pin. The purpose of this pin is to ensure the neck water channels line up with
the galleries in the torch body. The location pin registers in one of eight equi-spaced holes drilled in the neck seat.
This pin should not be removed because it is designed to line up the neck water channels with the water channels in the torch body.
Air-Cooled and Liquid-Cooled neck assemblies
The locking nut supplied with the neck assembly is designed to provide the correct pressure to the seating. It is tightened to 2.5Nm.
Care should be taken not to over tighten the nut because this may damage the neck seat.
Drive Roll replacement.
Drive Rolls can be supplied in sizes to suit 0.8, 0.9, 1.0, 1.2 and 1.6 diameter wire sizes. Your torch will have been supplied with a
standard 1.2 drive roll unless a different size has been specified on your order.
They are replaced by inserting a screwdriver blade into the drive shaft, whilst at the same time applying spanner force in a clockwise
direction to unscrew the drive roll from the shaft. The drive rolls are supplied with a
Left-Handed thread and are double grooved to
add service life to each roll.
The unused groove can be used by inverting the drive roll. The drive roll is suitable for both Steel and Aluminum wires.
