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
GB
© ESAB AB 2002
- 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
GB

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!

4.6 Installing the tool on the track
S Open and secure the rear rollers (2) using the plate springs (3) in accordance
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.

4.7 Fine adjustment
The rollers setting may need to be adjusted as follows:
S Loosen the support roller a little to tighten with Allen key as illustrated in fig. 9.
S Install the tool to the track and lock the rollers.
Figure 9
The measurement between plate spring and safety rail should now be 3 mm as
illustrated in fig. 10, If not, repeat the procedure.

3a Approximate vertical adjustment of the wire contact tip
3b Fine vertical adjustment of the wire contact tip
4 Lateral adjustment of the wire contact tip
5 Vertical adjustment of electrode and wire guide
6 Angling of electrode and wire contact tip
7 Adjustment of electrode distance before start-up
a) use the spacer screw (7) or AVC to adjust the electrode so that it points
towards the centre of the pipe (Alternatively edge (8) parallel with edge (9)).
b) then use set screw (5) to adjust the electrode distance to the item.

5 OPERATION
General safety regulations for handling the equipment can be found on
page 4. Read through before you start using the equipment!
WARNING
Danger to your health! Avoid breathing the welding vapours!
WARNING
Burning hazard at the workpiece and in the welding-zone of the welding head.
CAUTION
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.

6 MAINTENANCE
Regular maintenance is important for safe, reliable operation.
CAUTION
All guarantee undertakings from the supplier cease to apply if the customer attempts any
work to rectify any faults in the product during the guarantee period.
After a while, the edges of the track can develop a “beard”
(sharp edges). Remove these with a fine file, as there is
otherwise a risk of cutting injuries.
6.1 Daily
S Check all cables and hoses for damage.
S Clean the pipe welding tool.
6.2 Replacing wear parts
The electrode holder can be folded up as
illustrated in fig. 15 in order to replace the
electrode, gas lens and gas cover more easily.
Figure 15
6.3 Replacing wire
S Ease the pressure on the press roller by screwing in screw (1) as illustrated in fig. 16.
S Insert the wire by hand and release the press roller by screwing out screw 1.
