EN2.7 loading the filler wire and automatic feedAutomatic wire feed makes wire spool changes faster. When changing the wire spool, thepressure of feed rolls need not be released.Simply ensure that the groove of the feed roll matches the diameter of filler wire used. Releasethe wire end from the spool and cut off any deformed section. Be careful the wire does notspill from the spool sides.Straighten about 20 cm of filler wire and ensure the tip has no sharp edges. File if necessary, asa sharp wire edge may damage the wire gun liner - particularly softer plastic liners.Present the filler wire tip to the back of the wire feed rolls and press the wire inch switch onthe wire feed panel. Feed the wire to the gun contact tip and prepare to weld.NOTE! Smaller diameter filler wires may need to be loaded manually – with the feed roll pressurearms released. This is because it is easy to over estimate the pressure required to feed these smallerfiller wires. Too high feed roll pressures can easily deform filler wires and contribute to later feedingproblems.2.8 Duratorque™ 400, 4 wheel wire feed mechanismWire guide tubesø mm outlet tube middle tube inlet tubeSs, Al,(Fe, Mc, Fc)plastic0.6 W007437 W007429 W0072930.8 – 0.9 W007438 W007430 W0072941.0 W007439 W007431 W0072951.2 W007440 W007432 W0072961.4 W007441 W007433 W0072971.6 W007442 W007434 W0072982.0 W007443 W007435 W0072992.4 W007444 W007436 W007300Fe, Mc, Fcmetal0.8 – 0.9 W007454 W007465 W0075361.0 W007455 W007466 W0075371.2 W007456 W007467 W0075381.4 – 1.6 W007458 W007469 W0075392.0 W007459 W007470 W0075402.4 W007460 W007471 W00754124.8.2005 12:55FastMig MXF 63, 65, 678
