Robot manufacturers use Rotary Vector and Harmonic Drives to control manipulator motion. Excessive backlash in a drive is the main cause of repeatability problems.

The recommended allowable backlash in either type of drive is less than two Arc Minutes– two or more arc minutes indicates a worn-out drive and should be replaced.

The Drive Deflection Calculator is a stand alone program that can convert the measured backlash from any axis to arc minutes.

The Weld Parameter Calculator is a stand alone program designed for the beginner and intermediate robotic welding programmer.

The calculator gives starting values for amperage, voltage and wire feed speed for short circuit and spray transfer based on material type (steel, stainless steel and aluminum), material thickness, electrode type (solid or flux core) and size.

The deposition rate is calculated based on wire feed speed and wire diameter.
