Force Calibration
The iPAK2v2 weld controller has the ability to control weld force and read the weld force via analog signals. The analog
input allows the control to read the output of an external force sensor (load cell) or a proportional pressure sensor to
measure force. The analog output can be used to control a proportional air regulator valve to control weld force.
The analog input and output signals operate between 0
–
10V. The linear relationship between mV signal and the force
must be programmed into the iPAK2v2 during installation.
The calibration is based on a two-point lookup table and requires a weld force gauge.
The weld force can be calibrated in terms of kN or lbf. The units of measure are defined in the configuration section.
Refer to the Configure the Control section for more information.
