| IMPULSATION | Repeats WELD portion of sequence | 0-99 pulses 0-99 cool cy |
Drive a weld deeper into the each part, used on thicker metal welding |
| PREHEAT | Heat sequence before weld | 0-99 cycles 0-99% heat |
Controls heat when welding heavy parts |
| UPSLOPE | Ramps heat from selected starting point to WELD heat | 0-99 cycles 0-99% initial |
Helps with poor fit-up of parts and one method for galvanized steel welding. |
| DOWNSLOPE | Ramps head from WELD heat percent to selected end heat | 0-99 cycles 0-99% final |
Controlled heat ramp for heavy material welding and controlled cool ramp |
| POSTHEAT | Heat sequence after weld | 0-99 cycles 0-99% heat |
Control heat cracking; Smooth transition between impulses |
| QUENCH & TEMPER | Cool and reheat at end of welding sequence | 0-99 cycles 0-99% heat |
Reduces brittleness in high carbon steels |
| REPEAT | Automatic opening & closing of tips while initiation is closed | 0-99 cycles | Allows “automatic” operation of welder on long rows of repetitive welds |
| WATER SAVER DRIVER | Operates water saver solenoid | 1 minute | Turns water off 1 minute after last weld |
| TIP FORCE | Calculate needed pressure | 0-9,999 lb | Fast setups for WELD and FORGE |
| PRECOMPRESSION, POSTCOMPRESSION | Timed high pressure before first heat | 0-99 cycles ON 0-99 cy delay |
Lowers surface resistance at start of weld for consistency |
| FORGE DELAY | Timed delay of high pressure | 0-99 cycles | Reduces nugget internal cracking |
