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 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.
READ AND UNDERSTAND THE INSTRUCTION MANUAL BEFORE INSTALLING OR OPERATING.
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, LT S 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 details
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. The motor is powered by the control equipment (power source).
