SCOMARC is used when you are using coordinated motion (R1+S1:S1). Don't use it if you aren't doing a coordinated motion job
The rule of thumb with COMARC is:
- set up good set of weld parameters and weld job with the electrode at the leading edge of the puddle
- set up your weave amplitude and frequency using a Single weave (frequency is paramount)
- when ready, turn on COMARC MEASUREMENT MODE
- set S1E 197=1 to find out the appropriate parameter and time lag, and set the parameter
- set S1E 197=0 to find out the appropriate U/D and L/R and put those values in your job
- turn COMARC MEASUREMENT MODE to OFF
- test a weld
If it doesn't work, test it out from scratch again. If you screw something up in COMARC, sometimes it's just better to start over....
