A welder must shield the eyes and neck from the heat produced, absorbs IR and UV radiation, and flies off the job in a welding process from the splatter.
Usually, brazing is done on a torch or in a furnace. Dip, resistance, and brazing induction are other approaches.

Brazing binds the parts by heating them at a temperature of more than 840 ° F and adding a molten metal below that of the base metal. Capillary stimulation flows through the joint.
For gas soldering or oxygen cutting, when the lamp emits a bright yellow light, filter or lenses that absorb the yellow or sodium line are ideal in the visible light of the process.
Eye protection shall be provided in the form of the appropriate gloves for brazing operations not covered where necessary
The next thing is the lens ‘ shadow. Lenses vary from 4 (lowest shading) to 14 (darkest) in different shades. A lens with shading 10-12 is sufficient for most SMAWs. For a table and its corresponding lens shade number see Appendix A. Appendix A.
In many models and costs, helmets are available. Glass may be either be a fixed shade or an auto-defining variable shade. The choice of a user’s soldering helmet is due to personal preference and usability.
Both resistance soldering or brazing equipment operators and attendants shall use translucent facial masks or glasses to cover their faces or heads, depending on the task. When appropriate.
During all gas welding or oxygen cutting procedures, goggles or other appropriate eye protection should be added. Shows without side shields with appropriate filter lenses are required in lighting, torch brazing or inspection operations for gas welding.
