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 that the wire doesnot spill 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 feeder panel. Feed the wire to the gun contact tip and prepare to weld.NOTE! Smaller diameter filler wires may need to be loaded manually and 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 GT04 wire feed mechanismWire guide tubesø mm outlet tube middle tube inlet tubeAl, Ss (Fe, Mc, Fc)plastic0.6 W007285 W007273 W0072930.8 – 0.9 W007286 W007274 W0072941.0 W007287 W007275 W0072951.2 W007288 W007276 W0072961.4 W007289 W007277 W0072971.6 W007290 W007278 W0072982.0 W007291 W007279 W0072992.4 W007292 W007280 W007300Fe, Mc, Fcmetal0.8 – 0.9 W007454 W0075361.0 W007455 W0075371.2 W007456 W0075381.4 – 1.6 W007458 W0075392.0 W007459 W0075402.4 W007460 W007541FastMig MXP 37 Pipe8
