4.1.2 Using Weld Modes
The following sections describe how to use weld modes with their
associated parameters.
a. Time Mode
Use Time mode when consistency of welder cycle time is an important
part of your operation. For example, use in automated systems where
the welder cycle time must be limited to maintain overall system
speed.
In Time mode, the Time + and - Limits are inactive. The Collapse and
Absolute +Limits act as safeties. If reached, they will override the
controlling parameter and terminate Weld time. Use limits to monitor
the weld cycle, by comparing actual values to the set limits.
