Tight spot for rust and oxide.
Broad spot to limit charring.
Balanced spot for controlled spallation.
Best for seams and edges.
Follow grain to reduce scorching.
Use on joints and cracks.
Best for broad flat zones.
Safer than repeated line passes.
Use on planar open faces.
Good for localized edge blending.
Helps stay inside rounded areas.
Good for pits and pore cleanup.
Rotate freely on flat metal.
Stay near grain direction.
Match the local contour.
Higher frequency smooths scan lines.
Lower frequency limits heat.
Balances pore coverage and impact.
Wider spread speeds large passes.
Keep spread minimal on wood.
Avoid overworking weak edges.
Use 2-axis for fuller fill.
1-axis follows the grain.
Add 2-axis only if needed.
Tight spacing for dense oxide.
Wider spacing lowers heat.
Balanced spacing protects edges.
Use the upper end for heavy scale.
Stay low to prevent scorching.
Use moderate power on stone.
Higher overlap smooths tracks.
Lower overlap limits heat.
Moderate overlap helps pore cleaning.
Higher energy for thick scale.
Keep energy low on wood.
Stay below the fracture threshold.
