Page 6: Duty Cycle And Over-Heat
Duty cycle The letter “X” stands for Duty Cycle, which is defined as the portion of the time a welding machine can weld continuously with it’s rated output current within a certain time cycle (10 minutes). Over-heat The relation between the duty cycle “X” and the output welding current “I” is shown as the right figure. -

Welding (1) Place the Wire Spool onto the Spool Holder. Snip the wire from the spool being sure to hold the operation wire to prevent rapid uncoiling. Feed the wire into the wire feeder inlet guide tube through to the drive roller. -
Page 10: Wire Feed Roller Selection
4.3.1 Wire Feed The importance of smooth consistent wire feeding during MIG welding cannot be emphasized enough. Roller Simply put the smoother the wire feed then the better the welding will be. Selection Feed rollers or drive rollers are used to feed the wire mechanically along the length of the welding gun. Feed rollers are designed to be used for certain types of welding wire and they have different types of grooves machined in them to accommodate the different types of wire. -

4.3.2 Again the importance of smooth consistent wire feeding during MIG welding cannot be emphasized enough. The correct installation of the wire spool and the wire into the wire feed unit is critical to Wire achieving an even and consistent wire feed. A high percentage of faults with mig welders emanate Installation from poor set up of the wire into the wire feeder. -
Page 12: Mig Torch Liner Types And Information
4.3.4 MIG Torch Liner Types MIG Torch Liners The liner is both one of the simplest and most important components of a MIG gun. Its sole purpose is to guide the welding wire from the wire feeder, through the gun cable and up to the contact tip. Information Steel Liners Most MIG gun liners are made from coiled steel wire also known as piano wire, which provides the... - Page 13 Good weld quality and weld profile depends on gun angle, direction of travel, electrode extension (stick out), travel speed, thickness of base metal, wire feed speed and arc voltage. To follow are some basic guides to assist with your setup. Gun Position - Travel Direction, Work Angle: gun position or technique usually refers to how the wire is directed at the base metal, the angle and travel direction chosen.
- Page 14 Angle to Work - The work angle is the forward back angle of the gun relative to the work piece. The correct work angle provides good bead shape, prevents undercut, uneven penetration, poor gas shield and poor quality finished weld. Stick Out- Stick out is the length of the unmelted wire protruding from the end of the contact tip.
- Page 15 Too Fast Travel Speed - A too fast travel speed produces too little heat per mm of travel resulting in less penetration and reduced weld fusion, the weld bead solidifies very quickly trapping gases inside the weld metal causing porosity. Undercutting of the base metal can also occur and an unfilled groove in the base metal is created when the travel speed is too fast to allow molten metal to flow into the weld crater created by the arc heat.
