ESAB Welding Equipment AB, S-695 81 Laxå, Sweden, gives its unreserved guarantee that Feed selector from
serial number 450 complies with standard IEC/EN 60974-1, in accordance with the requirements of directive
(73/23/EEC).
2 SAFETY
Users of ESAB welding equipment have the ultimate responsibility for ensuring that anyone
who works on or near the equipment observes all the relevant safety precautions. Safety
precautions must meet the requirements that apply to this type of welding equipment. The
following recommendations should be observed in addition to the standard regulations that
apply to the workplace.
All work must be carried out by trained personnel well−acquainted with the operation of the
welding equipment. Incorrect operation of the equipment may lead to hazardous situations
which can result in injury to the operator and damage to the equipment.
1. Anyone who uses the welding equipment must be familiar with:
- its operation
- location of emergency stops
- its function
- relevant safety precautions
- welding
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
3. The workplace must:
- be suitable for the purpose
- be free from draughts
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.
- appopriate fire extinquishing equipment must be clearly marked and close at hand.
- lubrication and maintenance must not be carried out on the equipment during operation.

3 INTRODUCTION
Feed selector is switch unit for completing two wire feeders with one welding rectifier for
welding with use of two different electrode wires and one or two shielding gases.
It switches one pole of the welding rectifier and all needed control circuits between wire
feeders. Switching is performed automatically, by the signal from wire feeder. Wire feeder
that is not used is automatically disabled for the welding.
Thus it enables welding only with the same polarity for both processes.
Feed selector is basically intended for chopper and thyristor welding rectifiers, as they
provide possibility of remote voltage adjustment. In very limited cases it may be used also for
primary-tapped welding rectifiers, however they don't provide remote voltage adjustment and
changing the wire feeder will be accompanied with manual voltage changing.

cross section of the cable providing current to wire feeder should be applied.
6 MAINTENANCE
Inspection and cleaning.
Check regularly that the unit is free from dirt. The unit should be regularly blown
clean using dry compressed air at reduced pressure. More frequently in dirty
environments.
