cooled torch, the air has to be removed from the cooling circulation by running the cooler for
a few minutes.
CAUTION!
Wrongly connected water hoses can cause overheating and damage of the torch neck
and water-power cable. Regularly check the coolant level and throughput on the
cooling unit. Insufficient cooling might cause overheating and damage of the torch
neck and water-power cable.
NOTE!
To achieve an optimal gas- and water flow, place the cable assemblies and the gas
and water hoses as straight as possible. Kinked hoses will cause overheating and can
damage the torch. Protect cables and supply hoses from damage.
5.5Setting the level of shielding gas
Set the quantity of gas required on the gas regulator. The type and quantity of gas to be used
depend on the welding task to be performed.
5.6Checklist
Check the cable assembly before connecting it to the wire feed unit to confirm the wire liner
is suitable for the wire diameter and type.
Check the front end consumable parts on the swan neck, whether the correct contact tip etc.
is being used for the wire diameter and type.
5.7Changing wire

by either letting go of the trigger or by pulling the trigger a second time. Refer to the
instruction manual for the power source for more information.
DANGER!
The torch head might reach very high temperatures during operation, there is a risk of
severe burns. Let it cool down under observation, there is risk of fire. Do not place the
hot torch on or near heat-sensitive objects. For water cooled torches, the cooling
system should remain switched on for some minutes after the welding process has
been stopped.
When leaving the workplace the system must be secured against unintended
operation, preferably by switching off the power source.
Regular maintenance is important for safe and reliable operation.
Cleaning and replacement of the welding torch’s wear parts should take place at regular
intervals in order to achieve trouble−free wire feed. Blow the wire guide clean regularly and
clean the contact tip.

the liner into the torch as far as it will
go, do not apply force. Mark the end
of the torch neck on the liner.
4.Cut the liner to the correct length
using a projectile "X" measured from
the marking as shown in the figure.
Slightly chamfer the liner front end
after the liner has been cut to the
correct length.
NOTE!
If the liner has a bronze front end, first cut the plastic liner to a suitable length and
let the bronze liner stick out approximately 40-50 mm from the torch neck. Attach
the bronze liner to the front of the plastic liner and only then cut this liner
assembly to the precise length.
If it is difficult to insert the liner into the torch,
make a clean cut at the front end of the liner
and chamfer the edges (e.g. with a pencil
sharpener).
•Clean the inside of the gas nozzle regularly to remove welding spatter and spray with
ESAB® anti-spatter agent.
•Check the consumables for visible damage and replace if necessary.
6.6Checking the cooling system
