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.
