NOTE!
Field results may vary due to type of metal, compressed air supply, travel speed and
operator's experience.
The minimum and maximum settings are starting points for the rods indicated; with
relatively clean metal, an acceptable gouge groove should be expected. These
specific recommendations are based on the result of tests carried out on A36/ASME
mild steel.
For different types of metal, adjust the voltage setting and air flow for better
performance.
For any gouging issues other than performance, see the TROUBLESHOOTING
section.
