Manual Operation
Manual lifter operation is selected by placing the lower center toggle switch in the lower manual position. In
this mode, the unit manually jogs or slews slow or fast in the desired direction. If a cut is started while in the
manual mode, the torch moves only in response to the front panel manual move commands. The IHS, voltage
control, and end-of-cut retract functions are all disabled during manual mode.
Use your cut chart and the following steps to set up operations in manual mode:
1. Select manual mode with the toggle switch.
2. Set cut height with the up/down toggle switch.
The three types of manual motion are jog, slow and fast. Note that slow and fast types of manual motion are
time-based.
Manual Jog
Manual jog motion is useful for fine-tuning the torch height in manual mode. When the lower right manual
motion switch is momentarily switched into either the up or down position, the torch jogs approximately 20
thousandths in the desired direction. Repeat the momentary depression of the switch up or down to create a
series of discrete jog motions in the desired direction. This is useful for fine-tuning the torch height in manual
mode.
Slow Manual Motion
Continue to hold the manual motion switch for about ½ second after the jog has completed to create slow
manual motion in the desired direction. This motion should be at the IHS speed as determined by DIP SW #5.
Fast Manual Motion
Hold the manual motion switch for about one second after the start of slow manual motion to create fast
manual motion. The fast manual motion continues for as long as the manual motion switch is depressed.
