2 INTRODUCTION

The PRD 160 pipe welding tool is designed for TIG welding of pipes in combination

with the MechTig welding power sources.

There are several variants available: see on page 23.

During pipe welding, the tool runs along a track. The tracks are available in a large

number of dimensions, see table on page 7.

PRD 160 is attached to the track by a quick locking system, which grips the tool

tightly against the track and ensures that it is free from play.

The tool is available in five different versions. With the basic unit, only simple fusion

welding may be carried out. A wire feed unit, AVC (Arc Voltage Control) and weaving

may be selected to go with the basic version.

4 INSTALLATION

The installation must be carried out by a professional.

WARNING

Rotating parts can cause injury, take great care.

CAUTION

Danger of hose-burst ! Never use pressure of more than 3,5 bar on the coolant hoses!

Blow out all the cooling agent inside the system by means of compressed air into a

container.

CAUTION

The coolant must be handled as chemical waste.

4.1 Installation of track

Take care when installing and dismantling the track, due to the risk of crushing

injuries.

S Use the Allen key (1) supplied to hold the track as illustrated in fig. 1.

Figure 1

- 9 -

dsb3dea

S Place the track around the pipe and lock as illustrated in fig. 2.

Figure 2

The track should now be securely fastened to the pipe and should not be visibly out

of shape; if this is not the case, see under point 5.3.

4.2 Dismantling the track

S Dismantle the track in the reverse order.

4.3 Adjusting the track

On delivery of the track, the thrust bolts

are pre-set to that the track fits

concentrically on the pipe.

When adjusting the pipe dimension, it

is therefore important that every thrust

bolt is changed by the same amount.

There is a special, numbered Allen key

for this (1), see fig. 3.

S Always lock the thrust bolt with a polygon

wrench (2).

The above adjustments do not normally needs to be

performed until you come to a new batch of pipes.

Figure 3

4.4 Fine adjustment

Possible fine adjustment of the track

after usage for a period of time

S Adjust with wrench (1) as illustrated

in fig. 4 so that the parts (2) are

securely pressed in place by both

halves of the track, although

without the transition between the

halves deviating from the round

shape as a result.

Figure 4

- 10 -

dsb3dea

S Adjust the other joint as illustrated in fig. 5

according to the same premise.

Note! that both halves of the hinge

may need to be adjusted in order to keep

the centre of the hinge (the pin) directly

above the track's joint.

Figure 5

4.5 Adjusting the tool for the track

S Undo screws (1) and (2) on both sides of the trolley and adjust so that the centre

of the rollers (3) is pointing towards the centre of the track.

S Lock the screws (1) and (2), see fig. 6.

Incorrectly adjusted tools can result in excessively high motor current, which

produces a fault code (see programming manual MechTig for further information).

IMPORTANT!

Major deviations when adjusting the tool for the track increase the wear

on the track and rollers, and also cause the drive unit to be overloaded.

In order to protect the drive unit, there is a shear pin which breaks off in

the event of too high a load.

If the shear pin breaks off:

1. Dismantle the drive unit.

2. Remove the remnants of the shear pin with a mandrel.

3. Replace the shear pin with a new one.

NOTE that only original shear pins may be used!

with the arrows (4) and (5). See fig. 7.

S Incline the tool so that the front rollers (1) can be laid against the edge of the

track (6) (the electrode holder may have to be raised with set screw (7) or with

AVC).

S Fold carefully down the tool so that the gear wheels (8) engage in the intended

holes (9).

Figure 7

When the rear rollers (2) are in contact with the track (6), the tool is locked with the

aid of the plate springs (3) in accordance with the arrows (10), (11) and (12).

See fig. 8.

Dismantling is carried out in the reverse order.
