3.2.5.5. Main heat mode (parameter)
Regulation mode for main heat. Phase Angle (PHA) provides no
current regulation but uses a fixed SCR firing angle. Constant
Current Regulation (CCR) provides closed loop regulation to control
the current to a specified value.
3.2.5.6. Main heat (parameter)
Percent heat (0 – 99.9%) to be used in PHA mode.
3.2.5.7. Current (Main) (parameter)
Current to be used in CCR mode. This parameter also serves as
the main-heat monitor set-point for both PHA and CCR modes.
3.2.5.8. Monitor Current (main) (parameter)
Check this box to enable current monitoring during the main heat
interval. Current will be monitored to be within the Low and High
Limit parameters in this menu.
3.2.5.9. Post-heat mode (parameter)
Regulation mode for post-heat. Phase Angle (PHA) provides no
current regulation but uses a fixed SCR firing angle. Constant
Current Regulation (CCR) provides closed loop regulation to control
the current to a specified value.
3.2.5.10. Post-heat (parameter)
Percent heat (0 – 99.9%) to be used in PHA mode.
3.2.5.11. Current (post) (parameter)
Current to be used in CCR mode. This parameter also serves as
the post-heat monitor set-point for both PHA and CCR modes.
3.2.5.12. Monitor Current (post) (parameter)
Check this box to enable current monitoring during the post-heat
interval. Current will be monitored to be within the Low and High
Limits set in this menu.
3.2.5.13. Balance (parameter)
Seam welds only. Adjusts the current in the first half-cycle of any
pulse within a seam weld, to reduce transient effects.
