To improve quality control,
ease inspection and for regular calibration of resistance welding machines,
COB Industries, Inc. offers a EFG002 force meter for measuring resistance
welder electrode force.
This self contained
instrument uses a cell with a force sensor to provide an accurate digital
read out for auditing weld electrode forces.
Force can vary because of
changing factory air pressure, water in air causing air cylinders to
deteriorate, and loss of air pressure due to worn seals.
As with all welding
procedures, it is important to eliminate as many variables as possible in
order to achieve optimum welding consistently over a long period.
The Resistance Welder
Electrode Force Gauge allows electrode force to be measured as often as
necessary to ensure that this variable stays within tolerance, thereby
eliminating variations in resistance weld repeatability.
The weld force is read off
a digital display in the handle of the instrument. Special electronics
ensure that the true clamp load is displayed rather than any other readings
caused by initial head closure shock loads. (Shock loads can be monitored by
connecting the instrument to a storage oscilloscope.

This
unit has a voltage output which can be linked to a recorder and comes
complete with a battery charger with a 110 volt input for its internal
nickel cadmium battery. The unit weighs only 2.09 lbs.
