Removal of weld seams on stainless steel, steel and aluminum

1. Pre-sand with coarse grinding grits (60-100 grits) depending on the thickness of the welding seam.
2. As soon as the welding seam has almost been sanded to the level of the surface, change to a finer grit (120-180 grits). Work through the sequence of ever finer grits until the requested finish is achieved. Do not skip grit levels.
3. Use SCM belts to achieve a decorative finish:
   • Use a 100/120 or a 180/240 granulation SCM belt to achieve a dull finish. Machine should be set to "3" on the RPM pre-set dial.
   • Use a 400 granulation SCM belt to achieve a brilliant finish. Machine should be set to "6" on the RPM pre-set dial.

Removal of scratches from stainless steel and non-ferrous metal

1. The deeper the scratch, the coarser the grit is to be used.
2. Start sanding with the coarsest grit. Machine should be set to "2" on the RPM pre-set dial. Move the sander over the entire area of the scratch.
3. When the scratch is almost invisible, start working with ever finer grits until requested finish has been achieved.

NOTE: Do not skip grit levels as this will leave an unfavorable finish.

Achieving a polished mirror finish on stainless steel and non-ferrous metal

1. Start with a coarse grit. Work the surface until you have a "universal scratch pattern".
2. Step through the various grit levels (grit 400, grit 600, grit 1,500) until you have finished with the finest grit.

NOTE: Only proceed to the next grit level when a universal scratch pattern has been achieved.
