4.4 PANEL KEYS
21. WELD/TEST KEY - At power on the M-207A will always be in the TEST
mode. In TEST mode a weld sequence can be run but NO ARC will be
struck. The user must press this key to initiate WELD mode. Once this is
done the M-207A will stay in WELD mode as long as the same weld
schedule is displayed. Changing schedules will cause the system to return to
the TEST mode.
22. STOP PRINT KEY - This key will allow the user to stop the printing
process for any reason.
23. PAPER FEED KEY - This key allows the user to advance the paper in the
printer.

OPERATE MODE SWITCH
This is a three position switch with a locking key. When set to the desired
position (mode) the key can be removed to prevent any non-key holder from
changing the mode.
The OPERATE MODE SWITCH sets the M-207A to be run in any of three
separate modes as described below:
1. OPERATE/WELD SELECT POSITION - The OPERATE mode is for
standard welding operations. It allows access to all weld schedules and set-
up screens. All normal system operations, such as weld sequence, etc. are
performed in this mode. In this mode the operator CANNOT perform any
PROGRAMMING functions or changes to the memory such as creating,
modifying, transferring or deleting.
2. MODE LOCK - After a weld schedule has been selected it may be locked-in
to prevent selection of any other weld schedule. This feature is intended
primarily for when the operator is welding out-of-sight of the M-207A or if a
supervisor wishes to insure that ONLY a particular weld schedule is used.
3. PROGRAM/OPERATE - In order to CREATE, MODIFY, TRANSFER,
COPY or DELETE a weld schedule in the system memory, the mode switch
must be set to this position. All system operations, such as weld sequence,
can also be performed in this mode.
