WARNING
ARC WELDING AND CUTTING CAN BE INJURIOUS TO YOURSELF AND
OTHERS. TAKE PRECAUTIONS WHEN WELDING. ASK FOR YOUR
EMPLOYER’S SAFETY PRACTICES WHICH SHOULD BE BASED ON MANU--
FACTURER’S HAZARD DATA.
ELECTRIC SHOCK -- Can kill
S Install and earth the welding unit in accordance with applicable standards.
S Do not touch live electrical parts or electrodes with bare skin, wet gloves or
wet clothing.
S Insulate yourself from earth and the workpiece.
S Ensure your working stance is safe.
FUMES AND GASES -- Can be dangerous to health
S Keep your head out of the fumes.
S Use ventilation, extraction at the arc, or both, to keep fumes and gases from
your breathing zone and the general area.
ARC RAYS -- Can injure eyes and b u rn skin
S Protect your eyes and body. Use the correct welding screen and filter lens
and wear protective clothing.
S Protect bystanders with suitable screens or curtains.
FIRE HAZARD
S Sparks (spatter) can cause fire. Make sure therefore that there are no
inflammable materials nearby.
NOISE -- Excessive noise can da mage hearing
S Protect your ears. Use ear defenders or other hearing protection.
S Warn bystanders of the risk.

SAFETY
Users of ESAB welding equipment have u ltim ate responsibility for ensuring that any-
one who works on or near the equipment observes all the relevant safety precau-
tions.
Safety precautions must meet the requirements that apply to this type of welding
equipment.
The following recommendations should be observed in addition to the standard re-
gulations that apply to the work place.
All wor k m ust be carried out by trained per sonnel who are fam iliar with the operation
of the welding equipment.
Incorrect operation of the equipment may lead to a hazardous situation which can
result in injury to the operator and damage to the equipment.
1. Anyone who uses the welding equipment must be familiar with:
S its operation
S the location of emergency stops
S its function
S relevant safety precautions
S welding
To make this easier each switch, pushbutton or potentiometer is marked with a
symbol or text that indicates its function when activated.
2. The operator must ensure that:
S no unauthorized person is stationed within the working area of the equipment
when it is started up.
S that no--one is unprotected when the arc is struck
3. The work place must:
S be suitable for the purpose
S be free from draughts
4. Personal safety equipment
S Always wear recommended personal safety equipment, such as safety
glasses, flame--proof clothing, safety gloves.
S Do not wear loose--fitting items, such as scarves, bracelets, rings, etc., which
could become trapped or cause burns.
5. General precautions
S Make sure the return cable is connected securely.
S Work on high voltage equipment may only be carried out by a qualified
electrician.
S Appropriate fire extinquishing equipment must be clearly marked and close
at hand.
S Lubrication and maintenance must not be carried out on the equipment dur-
ing its operation.

TECHNICAL DESCRIPTION
Pipe weld ing tool A21 PRB is designed for TIG welding of pipe joints.
The pipe welding tool is water--cooled and designed for use with standard ESAB TIG
welding equipment -- PROTIG 315 and MECHTIG 315. If filler wire is required the
MEI 20 wir e feed unit can be used.

The pipe welding tool is designed according to a special clamping principle that al-
lows quick and accurate positioning on the pipe. A pair of jaws (1) lock the pipe weld-
ing tool onto the pipe when the locking lever (2) is pressed against the handle. Dur-
ing welding the only part that rotates is the gear ring (3).
TECHNICAL DESCRIPTION
-- 3 1 --
dsa2d1ea
Rotation is provided by a drive unit (4) consisting of a permanently magnetised DC
motor, which is supplied with current from the control equipment, and a tachometer
generator, which generates a voltage that is proportional to the speed of the DC
motor. T his voltage is fed back to the control equipment.
