Grinding

Warning

It is extremely important for satisfactory spot extraction equipment to be provided in areas where heat is generated by the work carried out there, such as welding, grinding, cutting and drilling.

Complement this with effective respiratory protection like a face mask with charcoal filter or better still a fresh-air mask.

When heated, all paints, sealants, adhesives and anti-corrosion agents give off substances which are injurious to health.


All surfaces to be welded must first be ground clean from any paint. Use a belt grinder. When spot-welding on galvanized sheet metal, the paint must be removed with a steel brush and hot-air gun so that the galvanized surface is not damaged. All-welded and plug-welded details must be ground to a fine finish after welding.

Important

Be careful not to grind away too much metal. The strength of the material must for no reason be weakened.


Use abrasive cloth 120 or finer on external surfaces. Coarser abrasive cloth leaves marks that will be visible after painting.
