Section 2.2: Wedge Adjustment
The placement of the Wedge is the most important part in Hot Wedge Welding. A properly placed
Wedge will be centered on the weld rollers from top to bottom as well as left to right and have the correct
angle, tilt and depth. The wedge must contact the fabric with the proper amount of presure pushing the
material into the weld rollers in order to achieve a superior weld.
WARNING!
The Hot Wedge Heating System near the Wedge and the Wedge Mounting Shaft is
very hot and will cause burning if not allowed to cool before handling. Turn the
Heat and Power Switches to the off position and allow the Hot Wedge Heating
System to cool for at least 20 - 30 minutes before touching with bare skin. Length
of time may vary depending on ambient temperature and environmental
conditions.
Adjusting Wedge
Wedge adjustment needs to be made at the start of every day when using the welder. When a Wedge
adjustment is needed turn the and heat switches to the off position and let the machine cool down for at
least 20 - 30 minutes (Length of time may vary depending on ambient temperature and environmental
conditions). Set the desired Weld Roller Pressure before adjusting the Wedge. Varying Weld Roller Pressure
(or P.S.I.) will change the position of the Weld Roller Pinch Point causing the Wedge to become misaligned.
Ensure that the Master Speed Control is set to 000 so that the Weld Rollers do not turn. Having the Speed
Control turned up with no material in the machine will allow the Weld Rollers to possibly suck the Wedge
into the pinch point possibly causing damage to the machine and giving an inaccurate wedge position. Turn
the Override Switch to the on position. This will swing the Wedge into place so that proper placement can
be checked and adjustments can be made. Make any adjustment needed, then check the Wedge
placement. Unlike the Hot Air Heating System, the Wedge placement will not change do to various
temperature changes. Therefore make all adjustments to the Hot Wedge Heating System while the Wedge
is cold to help avoid personal injury. Below are the steps that need to be taken before adjusting the Wedge.
NOTE:
Before making any adjustments to the Wedge ensure that the Speed Control is set to
“000” and the Weld Rollers do not turn. Also note; the wedge is slightly loose at the
point it is bolted to mount, to allow some float in the wedge when going over
multiple thicknesses.
1.Turn the Wedge Switch to the off position and wait for the Wedge to
cool down.
2.Turn the Master Speed Control to “000” to insure the Weld Rollers will
not turn.

3.Turn off the Heat Swing Switch
4.Turn the Override Switch to the run position.
5.Ensure the Outboard Puller Switch is on.
6.Remove the air pressure from the Heat Swing.
