arc tool systems, nozzle touch state , relieve the torch

[lanaprima]

1) In *arc tool systems*, the resume operation function is generally enabled. With this function enabled, return to the original stop position is always performed then arc is produced when not sometimes be performed.

2)For example, when the *nozzle touch state* is input through DI, a resume program is used to* relieve the torch slightly in the torch direction.* If the resume operation function operates, return to the original stop position is performed even when relieve operation has been performed. As a result, the nozzle touch state isthe original program resumes after the resume program terminates.
