SAFETY INSTRUCTIONS
For general safety instructions, please refer to the specific manual supplied with
the equipment.
AIRBORNE NOISE
Please refer to the specific manual supplied with the equipment.
Because the motor, reducing gear and plate all
have the same potential (welding +), the metal parts must not
touch the feed assembly.

3 - DESCRIPTION
Grease-lubricated gear motor M12 is made up of a wheel and a worm.
The gear motor unit assembly has a fixing plate (M22) with four insulated screws to
prevent arcing with the welding current.
The assembly also has two flange systems to orient the wire output in two planes in
relation to the fastening for optimised locating on the machines.
The plate has a shaft for two rollers that feed the electrode wire; the shaft may have
three rollers for two-wire applications.
The lock roller can be locked with the help of knob M6. Inlet E1 and the outlet from
the plate are symmetrical, with a ø of 18 mm. The fixing of the wire feed (A.S) or the
torch (MIG/MAG) is achieved by a tangent buffer.
Cover M17 guards the operator and can be opened with button M5.
Support tab M16 is provided to fix the powder container in the submerged arc
version.

USE
STARTING UP
Fix the gear motor assembly on the machine with four M10 screws with
a centre distance of 60mm (do not forget the insulating plate).
- Open the guard cover.
- Assemble the wire guide on the plate entry side and the torch (MIG-
MAG) or wire feed (A.S) on the plate exit side.
- Fit the rollers onto the shaft and lock with the nut and washer.
- Feed the wire in the plate and fasten it with the lock roller plate using
the knob.
- Close the guard cover.
ELECTRICAL CONNECTIONS
Sanyo Motor connections:
Connect the power supply cable to the male connector.
Tacho-generator connections:
Connect the cable to the female connector.
Check the motor rotation direction. If needed, reverse the two motor power
supply conductors and the two tacho conductors.
3A Motor connections:
See plan 9530 9202.
Because the motor, gear motor and plate all have the same
potential (welding +), the metal parts must not touch the feed
unit.
