Don't know what to teach nonwelders about welding? Here's a start

摘要

The first thing that should be covered is weld ing safety. This should begin with using the proper PPE-selecting the correct welding lens shade based on the process and the amperage being used; wearing quality welding gloves and a welding jacket to provide protection from the heat, sparks, and arc; and wearing heavy jeans or work pants without any fraying. Next is equipment safety. Check all cables for cuts, burns, and proper connections. Check the welding power source, electrode holder, or GMAW gun; check the work clamp for the rated amperage and proper connections.
