Unless otherwise indicated, nn represents any two-digit number from
0 – 99. nnn is a 3-digit number from 0 – 999. Exceptions to this
convention will appear next to the function.

Delay functions all have the same effect on the weld schedule:
They cause the control to wait for the number of cycles specified.
(Different names are assigned for describing the reasons for a
delay.)
During these functions, weld current does not flow and I/O
status is not changed.

Weld functions provide a specified amount of weld current for
the number of cycles programmed. The function selected also
selects the type of firing mode desired.
The weld function you select also tells the weld processor the
type of firing mode to use to control the energy provided to a
weld. Specify weld current as either
• A percentage of maximum available current, or
• The amount of secondary current.
This function tells the control how to compensate for changes in
the welding environment:
• %I uses a feature called Automatic Voltage Compensation.
AVC monitors primary voltage, using a nominal voltage
reference point (programmed in the setup parameters) to
determine when compensation is required for voltage swings
on the weld bus. This method does NOT compensate for
changes in the welder secondary circuit.
• Automatic Current Compensation ACC monitors the current
during each cycle. It compensates for changes detected
during the next cycle, to maintain secondary current at the
level programmed.
