1SAFETY
Users of ESAB servo slides have the ultimate responsibility for ensuring that anyone
who works on or near the servo slide observes all the relevant safety regulations.
The following recommendations should be observed in addition to the standard re-
gulations that apply to the work place.
1. General
All manoeuvres must be performed according to the given instructions by
personnel well familiar with the functions of the servo slide.
An incorrect manoeuvre, caused by a wrong move or an incorrect release of a
functional sequence, can lead to an abnormal situation that can injure the
operator and cause damage to the equipment.
Personnel working with the servo slide must be well familiar with:
Sthe handling of the slide
Sthe location of emergency stops
Sthe function of the slide
Sall relevant safety regulations
2. Live electrical components are usually semi--protected.
SAny work on electrical units shall be carried out by a qualified electrician.
3. Danger of the load falling down
SMake sure the base will resist all types of forces coming up during operation.
SCheck that the slide is fastened to the base with at least 4 M10 or M12 Allen
screws.
SNever overload the slide (see on page 88 the carrying capacity of the slide)
SCheck the condition of the belt regularly (at least every 200 hours).
SReplace the belt at least every 5 years, or as necessary.
N.B.
When replacing the belt or the belt pulley the load must be secured. Read
the pages 98 -- 99.
In case of a belt rupture the load will fall down.
WARNING!
4. Danger of getting clamped
SWhen the runner goes towards its end position
SWhen the belt protection is dismounted
5. Maintenance
SLubrication and maintenance of the slide must not be carried out when the
slide is in operation.

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
MANUFACTURER’S HAZARD DATA.
ELECTRIC SHOCK -- Can kill
SInstall and earth the welding unit in accordance with applicable standards.
SDo not touch live electrical parts or electrodes with bare skin, wet gloves or
wet clothing.
SInsulate yourself from earth and the workpiece.
SEnsure your working stance is safe.
DANGER OF GETTING CLAMPED
SMoving parts can cause damage. Therefore, be very careful!
FUMES AND GASES -- Can be dangerous to health
SKeep your head out of the fumes.
SUse ventilation, extraction at the arc, or both, to keep fumes and gases from
your breathing zone and the general area.
ARC RAYS -- Can injure eyes and burn skin
SProtect your eyes and body. Use the correct welding screen and filter lens
and wear protective clothing.
SProtect bystanders with suitable screens or curtains.
FIRE HAZARD
SSparks (spatter) can cause fire. Make sure therefore that there are no
inflammable materials nearby.
NOISE -- Excessive noise can damage hearing
SProtect your ears. Use ear defenders or other hearing protection.
SWarn bystanders of the risk.
MALFUNCTION
SCall for expert assistance in the event of malfunction.
PROTECT YOURSELF AND OTHERS!
READ AND UNDERSTAND THE OPERATING MANUAL BEFORE
INSTALLING OR OPERATING.

2 TECHNICAL DESCRIPTION
2.1 General
The A6 slide is designed to carry and transfer welding heads of different types of
welding plants. The slide can be mounted across the weld joint -- single or in a cross
saddle -- for adjustment or joint tracking. It can also be mounted along the weld joint
to bring about a welding movement.
The A6 slide is controlled over:
SControl box A6 GMD for joint tracking. (See instruction manual 443 403 xxx)
SControl box A6 PAK for positioning. (See instruction manual 443 405 xxx)
SControl box PEH for travel motion. (See instruction manual 443 745 xxx)
The A6 slide is a motorized linear slide. All movable parts are lodged in ball
bearings. The slide is available in different setting lengths from 60 to 1030 mm (see
dimension drawing on page 124) and in two different speed ranges.
2.2 The A6 slide consists of:
1. Slide profile, stiff U--profile.
2. Runner, lodged in open ball bushings, run-
ning over the axes which are supported by
the slide profile in their full length.
The driving system contains:
3. DC motor with worm gear.
4. Tooth belt transmission with built--in friction
clutch.
5. Ball screw with nu.

2.4 The carrying capacity of the slide
To simplify the schematical representation it is assumed that the load on the slide is
a weight and that the different mounting positions are confined to:
SVertical position
SStanding horizontal position
SLying horizontal position.
With the following co--ordinate directions the force of gravity works in the y, x and z
directions.

2.5 The linear bearing of the runner
Max permissible momemt--free load on the runner of the slide is 150 kg irrespective
of the mounting position of the slide.
Max permissible moment--generating load on the runner of the slide depends on the
mounting position. The centre of gravity of the load can be displaced from the centre
of the runner within an area, the further limit of which depends on the size of the load
according to the three diagrams below, where the slide is seen from above.
Max. load at vertical mounting Max load at standing horizontal mounting
Max load at lying horizontal mounting

Examplel 1:
SAn A6 SFD1 automatic welding machine is
mounted on a standing cross saddle.
SNote that the wire drum and the drum holder are
mounted on th slide profile of the vertical slide.
Example 1a:
SThe load on the vertical slide is about 43 kg.
SThe centre of gravity (TP1) is displaced 0,35 m
from the runner of the vertical slide in the z
direction.
SThe displacement of the centre of gravity in the x
direction can be neglected.
SThe load is far below the permissible load of 110
kg in this position.
*1) Permissible position of the centre of gravity at a
load of 40 kg.
*2) Permissible position of the centre of gravity at a
load of 100 kg.
Example 2:
SA load of 50 kg is fitted on a lying
horizontal slide.
SThe centre of gravity is displaced 0,4
m in the x direction.
SThe centre of gravity can also be dis-
placed 0,17 m in the y direction with-
out the max load being exceeded.
*1) Permissible position of the centre of
gravity at a load of 50 kg.
