WIRE SPOOL SETTINGS A350WP,A500WP, A600WP
There are 3 settings available below the wire spool. These affect how the wire spool
shaft, and AWT operate.
BB1 (Wire Rewind): Set between 70 and 80
When the wire breaks, the AWT unit must rewind the broken wire above the upper
guide. A larger wire spool requires it to be set to a higher number.
BB2 (Wire Bobbin Brake): Set between 30 and 40
This is the reversing torque on the wire spool. This reversing keeps the wire from
unspooling itself if the wire is stopped or broken. A larger wire spool requires a higher
setting.
Normal/ Thin Wire:
This switch changes the range of wire tension. Flip to thin wire when using .004” Dia. or
less wire.
Normal setting tension range = 600 to 2500 grams. Knob setting 8 will = 1200 grams
Thin setting tension range = 400 to 800 grams. Knob setting 8 will = 550 grams
