CHECKS AND PREFARATIONS PRIOR TO OPERATION
Feeding the Wire by Inching Operation
Inching Switch
Regardless of a kind of the wire, select the feed roller according to the wire diameter. When
the flux contained wire is used, it is necessary to adjust the wire pressurization force
slightly weaker than the solid wire. There are many kinds of flux contained wire and may require
delicately different pressurization forces, depending on their brands or manufacturing methods.
Care should be taken when adjusting the wire pressurization force.
For your safety. be sure to turn "off" the switch of the switch box located on the input
side of the welding power source (switch with fuse or no-fuse breaker or leakage breaker)
and POWER switch of the welding power source.
At the time of inching, do not peep through a tip hole to check if the wire is being fed.
It is very dangerous because the wire may fly out and stick into your face or eye.
1
Hold Down the inching switch to feed
the wire and release it when the wire
comes out of the tip of the welding
torch about 15 to 20 mm.
Caution
Feed a fine-diameter wire (
0.9) slowly
because it buckles easily.
