CHAPTER 3: OPERATING INSTRUCTIONS
SERIES 300 FAST RESPONSE WELD HEAD SYSTEM
3-12 990-115
You should set the self-check force to 10
pounds for directly opposed electrodes, as
noted on the HELP screen. For angled
electrodes, select the maximum force the
electrodes can tolerate without bending.

EMERGENCY STOP OPERATION:
You can configure the Emergency Stop
switch input at the CONTROL SIGNAL INPUT connector to operate either in the normally open or
normally closed mode. Note that the OPTION 3 screen is showing a selection of normally open
(NO). You toggle the selection to normally closed (NC) with the CHNG key.
Refer to Appendix B under
CONTROL SIGNAL INPUT Connector, Emergency Shutdown Input,
for
Emergency Stop signal input details. When you configure the Emergency Stop switch on the OPTIONS
3 screen, you must change the wiring to the emergency stop input on the CONTROL SIGNALS
connector. For normal operation, the circuit must be open in the NO case and shorted in the NC case.

MATERIAL SEARCH FORCE:
This is the force used to detect the weld material. You can set it
from 2 to 10 lbs., or to AUTO, by pressing the CHNG key. AUTO is the default setting. When set to
AUTO, the material search force will change according to the search (SRCH) rate setting of the
selected weld schedule (see table 3-2). With the SRCH rate set to FAST or MED, the force will be 3
lbs. When SRCH is set to SLOW, the force will be 2 lbs.
NOTE:
You will not be able to set a weld force lower than the MATERIAL SEARCH FORCE setting.

OBJECT DETECTION FORCE:
This is the maximum force to be used during the approach
mode (from upstop to search position). Referring to table 3-2, the object detection force is 10 lbs.
for FAST rate and 3 lbs. for MED and SLOW rate.
You can set the force from 3 to 10 lbs., or to AUTO, by pressing the CHNG key. AUTO is the default
setting. In the AUTO state, the object detection force will change according to the search (SRCH) rate
of the selected weld schedule. With the search rate set to FAST, the object detection force will be 10
lbs. With the search rate set to MED or SLOW, the object detection force will be 3 lbs.
[HELP] -- [FORCE LIMIT]
DURING INITIAL POWER UP AND SWITCHING FROM
DRESS MODE TO RUN MODE, THE HEAD CHECKS ITS
CALIBRATION. ENTER MAXIMUM FORCE THE HEAD
CAN USE. UNLESS THE HEAD IS SET UP TO USE
WITH ANGLED ELECTRODES, LEAVE SELF-CHECK
FORCE LIMIT TO 10 LB.
