BUG-6553 RETROFIT CAS HALL EFFECT FOR BUG-5700 TO BUG-5704
AUTOMATED HEIGHT CONTROL
The BUG-6553 Retrofit allows your Universal Bug-O-Matic to have Automated Height Control (AHC)
features. The AHC controls the welding tip to work distance and maintains a constant weld current, or
uniform weld penetration. AHC senses the actual weld current, compares this value to the setpoint, and
raises or lowers the welding gun accordingly. Controls for the AHC are self contained and its drives are
independent from those of the drive unit. AHC features a built-in time delay after the arc is struck, and
automatically shuts off when current drops too low (generally below 60 amp). The operator can tempo-
rarily override AHC using the manual jog switch while welding. AHC resumes as soon as the jog switch
is released. To disable the automated height control, move the Auto/Manual switch on the CAS Elec-
tronics Box (CAS-1555) to MANUAL.
NOTE: AHC is designed to work with the welding gun above the work piece. Contact Bug-O Systems
for other configurations.
