The default order defining various signal flows between the start and end of welding is as follows (steps (1) - (8)):
(1) Execute Motion Command for Welding [Start Welding]
: Welding process begins. For more information about welding, command structure and execution, refer to Chapter 7. Programming (TW) and Chapter 8. Monitoring/Adjustment During Execution.
(2) Discharge Protective Gas [corresponding to section (c) of ③ Start Discharge Time - start]
: This is the step during which protective gas that prevents oxidation during welding is discharged. ③Enter the discharge time.
(3) Early Welding Condition [corresponding to section (e) of ④ Start Current Time - start]
: This supplies the voltage/feeding speed to start welding after the discharge of the protective gas. If the main feeding speed/voltage is supplied without executing the early welding condition step during early welding, the welding status will become unstable, resulting in arcs not forming. The ratio between the target feeding speed during the early welding condition step and the target feeding speed of the main feeding condition is determined by ① Start Feeding Speed - start. The voltage ratio between the target voltage and the target voltage of the main welding condition can be determined with ②Start Voltage - start.
(4) Main Welding Section (Target Condition) Transition [corresponding to section (g), reaching the target condition after ⑤ Change Welding Condition Time]
: This adjusts the welding condition to the target condition after the early condition step. During ⑤ Change Welding Condition Time, the welding condition is progressively changed.
(5) Start Motion and Maintain Main Condition [available through the Welding Condition Adjustment popup]
: This starts the motion after the transition to the main welding section and maintains the set target condition. It is possible to adjust the welding conditions of the voltage/feeding speed/speed using the real-time welding condition adjustment popup. Even during real-time welding condition adjustment, ⑤ Change Welding Condition Time is applied, allowing the welding condition to change progressively over the set time.
(6) End Motion and End Welding Condition Transition Step [corresponding to section (g), reaching the End Feeding Speed after ⑤ Change Welding Condition Time]
: Once the motion ends, the welding condition progressively changes from the target condition to the end condition over the ⑤ Change Welding Condition Time. The ratio between the target feeding speed during the end welding condition step and the target feeding speed of the main feeding condition can be determined with ① Start Feeding Speed - end. The voltage ratio between the target voltage and the target voltage of the main welding condition can be determined with ②Start Voltage - end.
(7) End Welding Condition Step [corresponding to section (f) of ④ End Section Time - end]
: After the end welding condition transition step, the welding condition resets over ④ End Current Time - end.
(8) Discharge Protective Gas [corresponding to section (d) of ③ End Discharge Time - end]
: After the end welding condition step, the target voltage/feeding speed becomes 0, and the digital output corresponding to arc-on is turned off. This is the step where the protective gas that prevents oxidation during welding begins discharging, which lasts until the end. Enter ③ End Discharge Time - end.
