Example:
In the setting examples of F29: "5"; F30: "0"; F31: "5"; and f32: "0", the following diagram is available:
•
Before 100 ms of the torch switch ON (start signal "ON"), set the welding condition to "5" for F29 to F32 to read out the
welding JOB No.
•
To switch plural signals at the same time, carry out the operation within 40 ms.
•
From 40 ms before the torch switch OFF (start signal "OFF") to 100 ms after it, do not change the setting of "5".
*7: The "DC/PULSE switch" function and the "WAVE PULSE/PULSE switch" function can be used together. According to the
combination of external input terminal signals, welding method is optimized. The relationship between the welding method and
the signal is as follows:
