WARNING
READ AND UNDERSTAND THE INSTRUCTION MANUAL BEFORE INSTALLING OR OPERATING.
ARC WELDING AND CUTTING CAN BE INJURIOUS TO YOURSELF AND OTHERS. TAKE PRECAU-
TIONS WHEN WELDING. ASK FOR YOUR EMPLOYER’S SAFETY PRACTICES WHICH SHOULD BE
BASED ON MANUFACTURERS’ 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 take fumes and gases away from your breathing zone
and the general area.
ARC RAYS -- Can injure eyes and burn 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 damage hearing
S Protect your ears. Use earmuffs or other hearing protection.
S Warn bystanders of the risk.
MALFUNCTION -- Call for expert assistance in the event of malfunction.
PROTECT YOURSELF AND OTHERS!
3 INTRODUCTION
A21 PRB 17--49 / 33--90 / 60--170 is designed for TIG welding of tube joints.
The tube welding tools are adapted for connection to the LTO 160, LTO 250,
LTP 450, LTS 160, LTS 250, LTS 320 power source. If a filler wire is required, use
the MEI 21 wire feed unit.
The tube welding tools incorporate a special
gripping principle facilitating rapid and
accurate securing and location of the
tool on the tube. The pair of gripping
jaws (4) clamp the tool to the tube
when the locking lever (1) on the
handle is pressed in. Only the gear
collar (3) with the fitted d etails
rotates during welding.
The collar is powered by a drive
unit ( 2) consisting of a perm. magnet
DC motor and a pulse transmitter for speed
control. T he m otor is powered by the control equipment (power source).

6 OPERATION
General safety regulations for the handling of the equipment can be found on
page 59. Read through before you start using the equipment!
S Welding power sour ce LTO 160, LTO 250, see instruction m anual 0456 779 xxx.
S Welding power sour ce LTP 450, see programm ing m anual 0456 638 xxx.
S Welding power sour ce LTS, see programm ing m anual 0457 706 xxx.
To avoid the welding tool being damaged, check that the return cable is connected to the
workpiece and that the tungsten electrode is in the start position before the welding commences.
WARNING!
6.1 Securing the welding tool for welding
S Set the correct tube diameter using the adjusting screw (3), keeping the
locking lever (1 ) in the closed position.
S Open the welding tool by means of the locking
lever (1).
S For correct pre--clamping, turn
another quarter of a turn using
adjusting screw (3).
N.B. Harder clamping can deform
the tongs leading to centre
displacement and weld defects.
For welding using equipment for
tube diameters 8--17 mm (see
accessories, page 209) the welding
tool is to be fixed with the drive unit in
vertical position, as an alternative a support or relief could be placed under the
drive unit to prevent the welding tool turning round the tube.
S Close the welding tool again by means of the locking lever (1).
S Disengage the gear collar by way of the disengagement arm (2).
S Turn the gear collar (4) about 1.5 turns so as to wind up the connection cable.

6.2 Adjustments
Adjusting the position of the tungsten electrode
in the weld joint
S Adjust the electrode distance radially
using distance bolt (2).
S Adjust the wire nozzle ( 1) radially
by way of an Allen key and for
fine adjustment with wheel (2).
The spring load of the arm of the
electrode holder is preset on delivery.
If adjustment is necessary, please
contact your nearest ESAB
representative for information.
Inserting the filler wire
S See instruction manual for wire feed
unit MEI 21 (0443 831 xxx).
Adjusting the filler wire
S Adjust the filler wire nozzle (1) radially
by way of an Allen key. F or fine adjustment
use the wheel (2).
