WARNING!
Arc welding and cutting can be injurious to yourself and others. Take precautions
when welding and cutting.
ELECTRIC SHOCK - Can kill
• Install and ground the unit in accordance with instruction manual.
• Do not touch live electrical parts or electrodes with bare skin, wet gloves or
wet clothing.
• Insulate yourself from work and ground.
• Ensure your working position is safe
ELECTRIC AND MAGNETIC FIELDS - Can be dangerous to health
• Welders having pacemakers should consult their physician before welding.
EMF may interfere with some pacemakers.
• Exposure to EMF may have other health effects which are unknown.
• Welders should use the following procedures to minimize exposure to
EMF:
○ Route the electrode and work cables together on the same side of
your body. Secure them with tape when possible. Do not place your
body between the torch and work cables. Never coil the torch or work
cable around your body. Keep welding power source and cables as
far away from your body as possible.
○ Connect the work cable to the workpiece as close as possible to the
area being welded.
FUMES AND GASES - Can be dangerous to health
• Keep your head out of the fumes.
• Use ventilation, extraction at the arc, or both, to take fumes and gases
away from your breathing zone and the general area.
ARC RAYS - Can injure eyes and burn skin
• Protect your eyes and body. Use the correct welding screen and filter lens
and wear protective clothing.
• Protect bystanders with suitable screens or curtains.
NOISE - Excessive noise can damage hearing
Protect your ears. Use earmuffs or other hearing protection.

1 SAFETY
0463 697 001 -6- © ESAB AB 2021

Specification of the torch cooling circuit
(for water cooled torches only)
• min. water pressure: 2.5bar
• max. water pressure: 4.0bar
The necessary cooling power is dependent of the application, the welding parameters and
the length of the torch. Sufficiency of available cooling power can be verified by measuring
the return temperature of the cooling fluid. If the return temperature is above 60°C (140°F),
the cooling power should be increased or the welding current should be reduced.
Recommended minimum values for cooling power and coolant flow rate

For other application parameters or longer cables, refer to additional documents that may
have been included with your torch.
CAUTION!
Return temperatures of more than 60°C can cause damage or destruction of the
torch. The cooler must always be filled with sufficient cooling liquid, refer the user
manual of the cooling unit. In case of a high thermal load on the torch, use a cooler
with sufficient capacity. Use only special cooling fluid containing corrosion inhibitors
for welding torches. We recommend using ESAB CoolingFluid.
Duty cycle
The duty cycle refers to the time as a percentage of a ten-minute period that you can weld or
cut at a certain load without overloading. The duty cycle is valid for 40°C (104°F), or below.
Protection class
The torches protection class machine side (EN 60 529) IP3X
Enclosure class
The IP code indicates the enclosure class, i.e. the degree of protection against penetration
by solid objects of 2.5 mm Ø and greater. Omitting second characteristic numeral.

4 OPERATION
4.1 General
General safety regulations for handling the equipment can be found in the "SAFETY"
chapter of this manual. Read it through before you start using the equipment!
Read the operating instructions for the welding components, e.g. power source and connect
accordingly.
4.2 Connections
Tighten the connections for the torch carefully to avoid overheating the connection,
connection interference, mechanical damage or leakage of liquid or gas.
Connect water connections to the torch so that the red terminal is always connected to the
corresponding red terminal and the blue terminals are always connected to the
corresponding blue terminals.
4.3 Choice of electrode
By alloying the tungsten electrode with 1% to 2% lanthanum or cerium the electron discharge
is increased, which gives better striking and restriking and therefore increased arc stability.
Alloyed tungsten electrodes have a longer service life, tolerate higher currents and are less
likely to leave tungsten residue in the weld.
Pure tungsten electrode (AC) Green WP Used for welding light metal
alloys.
Cerium alloyed tungsten electrode
(AC/DC)
Grey WC20 Used for welding light metals
such as aluminium and
magnesium. Electrode tip must
be rounded when welding.
Lanthanum alloyed tungsten
electrode (DC)
Gold WL15 Usually used for welding
stainless steel, steel, copper,
titanium etc.
Lanthanum alloyed tungsten
electrode (AC/DC)
Black WL10 Used for welding light metal
alloys, stainless steel, steel,
copper, titanium etc.

4 OPERATION
0463 697 001 - 12 - © ESAB AB 2021
4.4 Grinding
Grind tungsten electrodes according to the following table:
NOTE!
Tungsten electrodes must be grounded lengthways. If they are incorrectly grounded,
the arc may be unstable. When the welding current is increased, the angle must
also be increased.
When welding with alternating current (AC), the electrode end must be gently rounded.
Grinding the electrode is then unnecessary. Light grading of the edge is sufficient. The
electrode forms itself if it is carefully overloaded. If the tip becomes ball shaped while welding
using alternating current, this is a sign that the current is too high for the diameter of
electrode being used.
Welding current Electrode angle
20 A 30°
20–100 A 30°–90°
100–200 A 90°–120°
over 200 A 120°
4.5 Bending of the flexible torch
The life of the flexible torch is limited. The
maximum bending angle should be
45degrees.
The life of the torch head can be prolonged by
proper technique.
Always make sure that the torch head is
supported by the thumb when you bend. This
prevents damages at sharp bendings.
4.6 Valve torches
CAUTION!
Do not operate TIG torches with an integrated valve in the torch neck on welding
systems equipped with an ignition and stabilization device.

5 MAINTENANCE
0463 697 001 - 13 - © ESAB AB 2021
