relevant safety precautions
welding and cutting or other applicable operation of the equipment
2. The operator must ensure that:
no unauthorised person is stationed within the working area of the equipment when it
is started up
no-one is unprotected when the arc is struck or work is started with the equipment
3. The workplace must:
be suitable for the purpose
be free from drafts
4. Personal safety equipment:
Always wear recommended personal safety equipment, such as safety glasses,
flame-proof clothing, safety gloves
Do not wear loose-fitting items, such as scarves, bracelets, rings, etc., which could
become trapped or cause burns
5. General precautions:
Make sure the return cable is connected securely
Work on high voltage equipment may only be carried out by a qualified electrician
Appropriate fire extinquishing equipment must be clearly marked and close at hand

WARNING!
Arc welding and cutting can be injurious to yourself and others. Take precautions
when welding and cutting. Ask for your employer's safety practices which should
be based on manufacturers' hazard data.
ELECTRIC SHOCK - Can kill
Install and earth the unit in accordance with applicable standards
Do not touch live electrical parts or electrodes with bare skin, wet gloves or
wet clothing
Insulate yourself from earth and the workpiece
Ensure your working stance is safe
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
FIRE HAZARD
Sparks (spatter) can cause fire. Make sure therefore that there are no
inflammable materials nearby
NOISE - Excessive noise can damage hearing
Protect your ears. Use earmuffs or other hearing protection.
Warn bystanders of the risk

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% lantha 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 when welding
light metal alloys
Cerium alloyed tungsten eletrode
(AC/DC)
Grey WC20 Used when welding
light metals such as
aluminium and
magnesium. Electrode
tip must be rounded
when welding

welding stainless steel,

etc.

4.4 Grinding
Grind tungsten electrodes according to the following table:
NOTE!
Tungsten electrodes must be ground lengthways. If they are ground incorrectly
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.

20 -100 A
100 -200 A

30°
30°-90°
90°-120°
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.

5 MAINTENANCE
NOTE!
Regular maintenance is important for safe, reliable operation.
WARNING!
The mains supply must be disconnected before cleaning.
CAUTION!
All warranty undertakings from the supplier cease to apply if the customer
attempts any work to rectify any faults in the product during the warranty period.
5.1 Daily
Check that all cables and hoses are undamaged and that there are no kinks in them.
Check that the gas nozzle is free from defects and suitable for the work in question.
Check that the shielding gas flows evenly and without restriction.
Check that the electrode is undamaged and that the electrode has been ground to the
correct angle.
Check the water flow at the unit's return line.
