1. Anyone who uses the equipment must be familiar with:
its operation
location of emergency stops
its function
relevant safety precautions
welding and cutting or other applicable operation of the equipment
2. The operator must ensure that:
no unauthorised person is stationed within the working area of the equipment
when it is started up
no-one is unprotected when the arc is struck or work is started with the
equipment
3. The workplace must:
be suitable for the purpose
be free from drafts
4. Personal safety equipment:
Always wear recommended personal safety equipment, such as safety glasses,
flame-proof clothing, safety gloves
Do not wear loose-fitting items, such as scarves, bracelets, rings, etc., which
could become trapped or cause burns
5. General precautions:
Make sure the return cable is connected securely
Work on high voltage equipment may only be carried out by a qualified
electrician
Appropriate fire extinguishing equipment must be clearly marked and close at
hand
Lubrication and maintenance must not be carried out on the equipment during
operation
WARNING!
Arc welding and cutting can be injurious to yourself and others. Take precautions
when welding and cutting.
ELECTRIC SHOCK - Can kill
Install and ground the unit in accordance with instruction manual.
Do not touch live electrical parts or electrodes with bare skin, wet gloves or
wet clothing.
Insulate yourself from work and ground.
Ensure your working position is safe
ELECTRIC AND MAGNETIC FIELDS - Can be dangerous to health
Welders having pacemakers should consult their physician before welding.
EMF may interfere with some pacemakers.
Exposure to EMF may have other health effects which are unknown.
Welders should use the following procedures to minimize exposure to
EMF:
Route the electrode and work cables together on the same side of
your body. Secure them with tape when possible. Do not place your
body between the torch and work cables. Never coil the torch or work
cable around your body. Keep welding power source and cables as
far away from your body as possible.
Connect the work cable to the workpiece as close as possible to the
area being welded.

FUMES AND GASES - Can be dangerous to health
Keep your head out of the fumes.
Use ventilation, extraction at the arc, or both, to take fumes and gases
away from your breathing zone and the general area.
ARC RAYS - Can injure eyes and burn skin
Protect your eyes and body. Use the correct welding screen and filter lens
and wear protective clothing.
Protect bystanders with suitable screens or curtains.
NOISE - Excessive noise can damage hearing
Protect your ears. Use earmuffs or other hearing protection.
MOVING PARTS - Can cause injuries
Keep all doors, panels and covers closed and securely in place. Have only
qualified people remove covers for maintenance and troubleshooting as
necessary. Reinstall panels or covers and close doors when service is
finished and before starting engine.
Stop engine before installing or connecting unit.
Keep hands, hair, loose clothing and tools away from moving parts.
FIRE HAZARD
Sparks (spatter) can cause fire. Make sure that there are no inflammable
materials nearby.
Do not use on closed containers.
MALFUNCTION - Call for expert assistance in the event of malfunction.
PROTECT YOURSELF AND OTHERS!
CAUTION!
This product is solely intended for arc welding.
WARNING!
Do not use the power source for thawing frozen pipes.
CAUTION!
Class A equipment is not intended for use in residential
locations where the electrical power is provided by the
public low-voltage supply system. There may be
potential difficulties in ensuring electromagnetic
compatibility of class A equipment in those locations,
due to conducted as well as radiated disturbances.

2 INTRODUCTION
This Instruction manual describes the use and maintenance of the Conventional Roller Beds,
referred to as roller beds in this document. Actions that must be carried out by the
manufacturer are not included in this manual.
This manual is part of the machine. Keep a copy of the manual with the machine and the
original in a safe place. If the roller beds are sold, supply the manual with it.
The pictures and diagrams used in this manual are for illustrative purposes only, to help
explain instructions in the text. The equipment supplied may differ slightly.
2.1 Equipment
The roller bed drive is supplied with:
Drive units
Mounted control cabinet
Pendant
Base frame
Instruction manual
The roller bed idler is supplied with:
Idler units
Base frame
Instruction manual
2.2 Purpose and function of roller beds
The roller beds are designed to aid the welding of cylindrical vessels.
By using independent drive and idler units, vessels of varying lengths can be placed on the
roller beds supported on the roller bed wheels. The wheels can be adjusted on the
baseframe to accommodate different vessel diameters.
2.3 Nomenclature used in this manual
Drive unit Roller bed section with powered wheels.
Idler unit Roller bed section with free wheeling wheels.
Roller bed set A set consists of 1 drive unit and 1 or more idler units.
Baseframe The frame the drive or idler wheels are mounted on. These are
pre-drilled so that the wheel brackets can be positioned for different
vessel diameters.
Wheel bracket The bracket which houses the roller bed wheels. This is bolted down
to the baseframe.
Control panel Electrical control box mounted on the drive unit.
