Miscellanous Notes

Description
WorkPoint in Amps, Trim
in Volts
These settings should be set to the desired values in the weld control before any jobs
are setup. Once a job(s) is setup, these values must not be changed, else the job will
be considered invalid. If these values are changed, then the welder must be reset in
order to welding with the LGA Interface.
Sending an Invalid Job
If an invalid job is sent to the board, it will be accepted and saved, but you can not
weld with it. An invalid job is a job that has a non-existent welding mode or a
WorkPoint or Trim value with the wrong units.
Updating the current Job
Number in use.
If an updated Job is download to the board, any new setting will not take effect if that
Job is currently in use and welding. When the welding goes to idle, it will be updated.
If weld mode uses gas
If the welding mode has the Gas as a required, the gas will be turned on when the
Preflow or Strike is entered first. So the user does not have to turn on the Gas Purge
bit on the I/O.
Using GTAW processes
When a GTAW process is currently selected and a Tig Gas object is detected in the
system, then this Gas solenoid will be enabled when the Sequencer turns on gas or
when the I/O Gas Purge bit is enabled. When a non-GTAW process is used, the gas
solenoid found on the Wire Drive will be enabled. If a gas solenoid is on and a new job
is selected and the process type is changed, the previous turned gas solenoid will
stay on. After this solenoid is turned off, then the correct solenoid type will be turned
on when commanded.
Setting Feedback Rate
Used to set the feedback rate in the Weld Controller for the Current and Voltage and
the WFS feedback rate in the Wire Drive. This takes effect only after reset. If this
value is greater than the present setting, then no update will be done.
Enable Wire Stick Check
After change this setting the system must be reset in order to take effect.
Enable Burnback on a
Fault
If Enable Burnback on a Fault is false, then if welding and a fault occurs, the
sequencer should turn everything off and go to the Idle state immediately. If the
Enable Burnback on a Fault is True, then if welding and a fault occurs, the sequencer
will transition to the Burnback state if a Burnback state time is set. If it was the Weld
controller that actually faulted, it stil will transition to the Burnback state, but the weld
output will be off so no actual burnback will be done.
Production Monitoring
Profile
The LGA Interface can be setup to select the Production Monitoring Profile number
when a job is selected. The valid profiles numbers range from 1 to 200. If an invalid
profile number is set in the job setup, then the LGA Interface will not write any profile
number out and Production Monitoring should remain using the last valid profile
number.
Job Mode with Parameter
Inputs
The I/O control bit to put the interface into this mode must be set to True before the
welding state is entered. If this not done the welder will use the values defined in the
Job setup when the weld state is first entered.
If the input is set to False when in the weld state, the welder will keep using the last
inputted values that were sent over the I/O interface.
