3 INTRODUCTION

A21 PRC 17--49 / 33--90 / 60--170 is designed for T IG welding of tube joints.

The tube welding tools are water--cooled and include weaving function (6) and

automatic arc length control (by control of the arc voltage = AVC) (5). The tools are

adapted for connection to the power source LTP 450. When filler wire is requir e d the

MEI 21 wire feed unit is to be used.

The tube welding tools incorporate a special gripping principle facilitating rapid and

accurate securing and location of the tool

on the tube. T he 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).
