[Cause]
The arc-start height adjustment macro was skipped because single-step mode, dry run, or welding-disabled mode was active. If Lincoln welding equipment is used, Arclink communication may not have been established.
[Countermeasure]
Exit single-step and dry-run modes, or enable welding, and execute the arc-start height adjustment macro. To perform arc-start height adjustment while welding is disabled, set "Skip when welding is disabled" to "Disabled" on the arc-start height adjustment setup screen. If Lincoln welding equipment is used, establish Arclink communication. To suppress this warning message, change system variable $AWSTHOF.$POST_WARN to FALSE.
