Adjusting Tong and Operating Lever Pressure
WARNING! TO PREVENT SERIOUS INJURY AND
ELECTRIC SHOCK: Prior to adjusting the Tong and
Operating Lever pressure, make sure the Spot Welder
is disconnected from its electrical supply source.
NOTICE: Excessive Tong pressure can damage the
Electrode Tips. Do not attempt to hold the workpieces
together by using the Tongs under high pressure as
a clamp or vise. To avoid damage, use separate
clamps to hold workpieces together if needed to
make good contact at the intended weld point.
1. The amount of pressure applied by the Tongs
is adjustable, and should be checked and/or
set before operation. Correct Tong pressure
is necessary to create a proper weld and to
prevent damage to the Electrode Tips.
2. If the Tong pressure is too weak, and the
workpieces are loose when the Tongs close, severe
arcing will occur between the workpieces when
current is applied and no weld will be produced.
To increase the Tong pressure, loosen the front
Jam Nut. The more the front Jam Nut is loosened,
the greater the pressure on the Electrode Tips
when the Operating Lever is pushed down to
close the Tongs. When the desired pressure is
achieved, turn the rear Jam Nut toward the Upper
Tong Holder to lock in position. See Figure D.
3. If the Tong pressure is too strong, the weld
nugget will dimple, and molten material will be
forced out around the weld point. To decrease the
Tong pressure, loosen the rear Jam Nut and turn
the front Jam Nut toward the Upper Tong Holder to
lock the desired pressure in position. See Figure D.
4. Adjusting the Cap Screw at the rear of the Fixed
Handle will determine how firmly the Tongs apply
pressure to the workpiece. The farther down
the Cap Screw is turned, the farther down the
Operating Lever will close and the more Tong
pressure will be applied. Adjust the Cap Screw to
allow the Operating Lever to be raised easily after
completion of the welding process. See Figure E.
5. The pressure required to push down the
Operating Lever may be adjusted by turning
the Hex Nuts located on each side of the Front
Housing clockwise or counterclockwise to loosen
or tighten the Lever action. See Figure D.
