The helmet holds the lens. Lenses come in different shades (darkness). Use the correct shade. Most welding applications call for a shade #10. TIG weldors usually use a shade #9. Plasma applications can call for a shade #11.

Do you need a darker or lighter welding helmet for arc welding?

A darker helmet shade, compared to gas welding. A shade of 10 for 70 amps, it works up from there, or you could buy a auto-darkening hood which you can see out of, but when you strick the rod on the metal it darkens to the right shade for you to still see out of.

For rebar that is embedded in a poured slab or in a sprayed concrete wall when is welding required and when will using twisted wire suffice Can you include a link to the standard Thnx.?

Tie wire should be used always, not welding. Rebar integrety is comprimised when welded. A specific grade of rebar, A706, exists for welding but otherwise, its is not advised that rebar be welded. See below:Q: When is it appropriate to use welded splices in the field? A: The ACI 318 Building Code requires the architect/engineer to indicate the type and location of welded splices of reinforcing bars on the project drawings or in the project specifications. The ACI 318 Building Code further requires that all welded splices should conform to the Structural Welding Code for Reinforcing Steel published by the American Welding Society, which requires the project contractor to prepare written welding procedure specifications (WPS) for all welded splices. These will depend heavily on the assessment of carbon-equivalent (CE) and other rebar properties as determined by the mill test reports that accompany each shipment. For more information about welding reinforcing steel, see the American Welding Society's (AWS)Structural Welding Code for Reinforcing Steel.Q: Can tack welding be used to hold reinforcing bars during assembly? A: Field tack welding should never be used as a substitute for tying in assembling and securing reinforcing bars. Rare exceptions are specified in the International Building Code.Source link: http://www.crsi.org/contractors/faqs.html

What is a welding helmet?

The helmet takes the place of a safety helmet and gives a firm attachment to the flip-up visor. When welding the visor is dropped to protect the eyes from the light coming from the welding torch. It is obviously difficult to see anything through the visor except the filtered welding torch flame. The visor can be flipped up to let the welder clearly see the result of the weld, or to move to another spot.

What does ARC mean in ARC welding?

In arc welding the electrode (welding rod) is held just a little space away from the workpiece and electric current jumps from the electrode to the work piece carrying material from the rod with it. This material is deposited at the weld site mixed with molten metal from the workpiece. The jumping current is referred to as the arc. You can see it if you are wearing welding glasses with the proper dark lens. Looking at the arc without eye protection will often result in a splitting headache later and, if done recklessly and too long, permanent eye damage can result---in other words, blindness.
