CHAPTER 1: DESCRIPTION
SERIES 300 FAST RESPONSE WELD HEAD SYSTEM
1-6 990-115
Control Keypad
This cluster of six keys allows you to access the various control screens on the
display and control the editing (changing) of data on the screens.
[MENU]
Provides a screen (display) menu listing of user options that are
common to all weld schedules.
[PROG] Each time you press [PROG], it accesses the next programming
screen in a sequence of programming screens. It also disables the RUN state.
[RUN] Pressing [RUN] exits the PROGRAM state (the state in which the Weld Head Control is to be
programmed) or the MENU (user options) state, and enters the RUN state. In the RUN state, you can
view the screens while you make a weld and analyze weld force, weld current, and electrode position
(follow-up) relationships dynamically.
[CHNG] Pressing [CHNG] allows you to either:

Select different screen menu options, or

Restore the previous contents of a screen programmable field, or

Toggle through the series of screen of the RUN state.
[HELP] Accesses detailed on-line help screens for any program variables or alarm messages. The
screens provide helpful information about any menu option or flashing programmable field. Pressing
[HELP] A second time returns you to the original screen state.
[SAVE] This key is active only in the PROGRAM state. Pressing [SAVE] saves the changes to the
weld schedule that you just entered to the program screen, then automatically selects the RUN state.
Select Keypad
This is a cluster of four arrow keys. In the RUN state, you actuate them
to increment or decrement weld schedules. In the alphanumeric
PROGRAM or MENU states, you actuate them to move the cursor up,
down and sideways on the screens to select value field for editing. In the
graphical PROGRAM state, you can increment or decrement programmed
values.
WELD/NO WELD Switch (Power Supply). Placing this switch in the NO WELD position cuts
off weld current. It is the position that is required to adjust the weld head. Note that a complete
electrode positioning sequence can be executed without weld current flowing. You must place the
switch in the WELD position to make a weld.
RUN/DRESS Switch (Weld Head Control). Placing this switch in the RUN position allows
normal execution of the weld cycle. In the DRESS position, it allows you to dress (clean) the
electrodes by executing a setdown on cleaning material that you insert between the electrodes.
Setdown force for dressing is programmable.
