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

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.

INSTALLATION

INSTALLATION

General

1. MECHT IG 315, see operating manual 443 420.

2. PROTIG 315, see operating manual 443 419.

3. Wire feed unit MEI 20 see operating manual 443 421.
