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 regulations 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:
S the handling o f the slide
S the location of emergency stops
S the function of the slide
S all relevant safety regulations
2. Live electrical components are usually semi--protected.
S Any work on electrical units shall be carried out by a qualified electrician.
3. Danger of the load falling down
S Make sure the base will resist all types of forces coming up during operation.
S Check that the slide is fastened to the base with at least 4 M10 or M12 Allen
screws.
S Never overload the slide (see on page 88 the carrying capacity of the slide)
S Check the condition of the belt regularly (at least every 200 hours).
S Replace 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.
WARNING!
In case of a belt rupture the load will fall down.
4. Danger of getting clamped
S When the runner goes towards its end position
S When the belt protection is dismounted
5. Maintenance
S Lubrication and maintenance of the slide must not be carried out when the
slide is in operation.

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
MANUFACTURER’S 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.
DANGER OF GETTING CLAMPED
S Moving parts can cause damage. Therefore, be very careful!
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 keep fumes and gases 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 ear defenders or other hearing protection.
S Warn bystanders of the risk.
MALFUNCTION
S Call for expert assistance in the event of malfunction.

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:
S Control box A6 GMD for joint tracking. (See instruction manual 443 403 xxx)
S Control box A6 PAK for positioning. (See instruction manual 443 405 xxx)
S Control 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, running 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:
S Vertical position
S Standing horizontal position
S Lying horizontal position.
With the following co-- ordinate directions the force of gravity works in the y, x and z
directions.
