TOOL ADJUSTMENT – WELD 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 small slotted screw, located beneath the weld housing at the rear of the tool, using a small screwdriver. Turn the screw clockwise to increase weld time and counter-clockwise to decrease weld time.
Establishing the correct weld time is a matter of trial and error and should be conducted as follows:
- Adjust the screw in 1/16 to 1/8 turn increments only.
- Apply a strap and make a weld.
- Compare the weld made with the illustrations shown above. A good weld will displace some material along the outer edges of the joint.
- If you cannot produce an acceptable joint or have any questions about whether your tool is producing good weld strength, contact your Signode Sales Representative.
