Transcool 351

Torch Water Cooling Unit

Introduction

This high efficiency torch water cooling unit has been
designed to be used with the Transtig 203i, 253i or 353i
TIG welding equipment, although it can also be used as a
free standing unit with other similar equipment. It operates
from either a 115V or 230V 1 phase 50 Hz electricity
supply. The metal enclosure contains a moulded reservoir
tank, motor/pump assembly, radiator, cooling fan and water
flow detection circuit. In the event of failure of the water
flow an alarm will sound and a warning light will
illuminate on the control panel.

Specification:

Electricity Supply: 115V or 230v ±10%

1 phase 50 Hz

Capacity (excl torch) 5 litres
Working Temperature 47ºC (300A/22V)
Water Flow Rate: 2 lpm (3.8m Torch)
Dimensions (LxWxH): 610mmx290mmx250mm
Weight: 17.5 kg

Coolant

Distilled water is normally recommended however, where
there is a possibility of the coolant freezing, distilled water
with a minimum of 25% glycol antifreeze added should be
used.

Installation

1. Attach the torch water inlet hose (blue) to the quick
connector marked with the water out symbol.

2. Attach the torch water return hose (red) to the quick
connector market with the water in symbol.

3. Fill the tank with coolant, see above.

4. Connect the mains lead to a suitable 115V or 230V ac
supply.(A 230v supply is provided by the Transtig 203i,
253i and 253i). Check the supply is fused at 6.3A

5. Switch on and allow the coolant to circulate. Note that
the audible alarm may sound while air is pumped out of the
system.

6. Top up the coolant, to level with the top of the sight
window.

WARNING!

1. Do not operate the unit without coolant. Check coolant
level regularly.

2. Do not operate the unit without the torch connected.

Maintenance

WARNING!

Always isolate the unit from the electricity supply before
removing the cover.

1. Check the coolant level regularly. If necessary top up
using the same coolant as already used.

2. At least once a year drain down the coolant, flush out the
system and refill with fresh coolant.

3. To keep the unit at peak performance, the cover should
be removed at regular intervals (at least once per year) and
any accumulated dust blown out.

4. If the unit is taken out of service for long periods, the
system should be drained, and then refilled with fresh
coolant to keep the pump ‘wet’.

Inspection and repair of this equipment should only be
carried out by a suitably qualified person. Defective parts
should be only be replaced by genuine Murex parts.
