Using Corner Slowdown
for Mechanized Cutting
Tools Required
Setting CSD Output
Disconnect primary power at the source before disassembling
the power supply, torch, or torch leads.
Frequently review the Important Safety Precautions beginning on
page iii of this manual.
The corner slowdown (CSD) function provides a reduction in
output current which corresponds with the reduced travel speed
of a mechanized torch as it changes direction at a sharp corner.
When activated (by CNC or other control device) corner slow-
down eliminates excessive metal removal in corners.
Normally open (NO) contacts (supplied by the control device)
close when the torch travel speed decreases through a corner.
When the contacts close, power supply output drops to a preset
current level.
Small Standard (Slotted Head) Screwdriver
The corner slowdown adjustment is located on the upper front
panel (see Figure 4-A, page 27). CSD output is a percentage of the
main output setting. Minimum output is 15 amps during CSD.
Turn the control clockwise to increase CSD output. Maximum
CSD output is 100% of the main output level. Typically, CSD
output should not be set lower than 70% of the main current level
to insure full arc penetration during corner slowdown. When
adjusting output current level, corner slowdown output should
be adjusted accordingly.
