Adjustments - Signode VT-10 Operation, Parts And Safety Manual

TOOL ADJUSTMENTS
WELDING TIME
Weld time has been factory adjusted to provide acceptable weld strength when using High
Strength Tenax (polyester) type strap. Weld time may need to be adjusted due to air supply
differences, tool wear, etc. Adjustments are made by turning the adjustment screw, located on the
cover plate, using a small screwdriver. Turn the screw clockwise to increase weld time and
counterclockwise to decrease weld time.
Establishing the correct weld time is a matter of trial and error and should be conducted as
follows.
1. Remove the cap which protects the adjustment screw.
Adjust the screw in 1/8 to 1/4 turn increments only.
2. Apply a strap and make a weld.
3. Compare the weld made with the illustrations shown on
page 13 of this manual. A good weld will displace some
material along the outer edges of the joint.
4. If you are unable to produce an acceptable joint or if you
have any questions as to whether your tool is producing
good weld strength, contact your Signode Sales
Representative.
5. Replace the cap over the screw.
WELD COOLING TIME
Cool time has been factory adjusted to allow the proper time for a weld to properly cool. The cool
time adjust controls how fast or slow the main piston bleeds off air pressure allowing the weld
pads to separate from one another.
Cool time may also need to be adjusted due to air supply differences, tool wear, etc. Adjustments
are made similar to weld time. Turning the screw clockwise increases cool time and
counterclockwise to decrease cooling time.
Establishing the correct cool time is a matter of trial and error and should be conducted as
follows.
1. Remove the cap which protects the adjustment screw.
Adjust the screw in 1/8 to 1/4 turn increments only.
2. Apply a strap and make a weld.
3. A properly adjusted cool time should allow the strap
joint to cool for approximately three to five seconds.
NOTE: Cool time which is too short may lead to strap
joint separation.
4. Replace the cap over the screw.
