BUG-O Systems CAS-2050 - Manual (Page 5)

INTROdUCTION:
The CAS-2050 is an Automatic Height Control ( aHC) for the WPD-1100 Linear Weaver that controls
the welding tip to work distance and maintains a constant weld current, helping to provide uniform weld
penetration. The CAS-2050 senses the actual weld current, compares this value to the set point, and
raises or lowers the welding gun accordingly.
The CAS-2050 features a built-in time delay after the arc is struck, and automatically shuts off when the
current drops too low (generally below 60 amps). The operator can temporarily override the Automatic
Height Control using the Up – down JOG Toggle Switch on the Remote Control (CAS-2051-10)
while welding. Automatic Height Control resumes as soon as the jog switch is released. To disable the
Automatic Height Control, move the Manual – automatic Toggle Switch on the Remote Control (CAS-
2051-10) to the manual position.
OVERVIEW
CAS-2050 AHC is available as original equipment or as a retrofit unit designed to provide
Automatic Height Control on BUG-O Modular Drive Systems ( MdS) with the WPD-1100 Linear
Weaver. The CAS-1500 Height Slide Assembly replaces the welding clamp originally supplied
on the Linear Weaver.
