3.12 Feed Roller Pressure Adjustment
NOTE!
Before attempting to set the drive roller pressure you must select GMAW mode on the front panel. See
earlier in section 3 for information on how to select this feature. Once selected it will allow the activation of
the drive roll when the trigger on the MIG Gun is activated.
The roller on the swing arm applies pressure to the grooved roller via an adjustable tension devise. The Tension Adjuster should be set
to a minimum pressure that will provide satisfactory wire feed without slippage. If slipping occurs, and inspection of the wire out of the
MIG Gun reveals no deformation or wear, the conduit liner should be checked for kinks or clogging from metal flakes. If this is not the
cause of slipping, the feedroll pressure can be increased by rotating the Tension Adjusting knob clockwise. The use of excessive pres-
sure may cause rapid wear of the feed roller, motor shaft and motor bearings.
NOTE!
Genuine ESAB Velocity contact tips and liners should be used. Many non-genuine liners use inferior materi-
als which can cause wire feed problems.
3.13 Feed Roller Alignment
The bottom Feed Roll is adjustable in and out to provide for best alignment of wire as it feeds into the outlet guide. To adjust the roll do
the following and refer to Figure 3-13. Note, the welding wire is not shown in order to more clearly see the groove in the feed roll.
1. Place a wrench on the adjusting bolt (number 2) and hold in place while you loosen the locking screw (number 1) with a hex
wrench
2. With the locking screw loosened, turn the adjusting bolt right or left to align the feed roll (number 3) so the groove is aligned
with the outlet guide (number 4).
3. With the feed roll aligned, place a wrench on the adjusting bolt and hold it in place while tightening the locking screw with the
hex wrench. If the adjusting bolt moves before the locking screw is secured then the alignment will change.

NOTE!
It may not be possible to align with both the inlet and outlet guide at the same time. The outlet guide is the
one that needs to be aligned to for best wire feeding.
