Before selecting the welding equipment you must have adequate knowledge regarding the welding process. Welding is a process in which metals are fused with electricity and high heat.
Would you like to know the factors that influence the selection of welding helmets? You need to check for the factors like thickness, kind of material and various other specifications while looking out for the best welding helmet. According to safetyonline.com, welding helmets should be thoughtfully engineered to facilitate the work of welders comfortably and proficiently and maximize the work performance.
You get many options of welding helmet depending on auto-darkening or passive lens, viewing size, variable or fixed shade, three sensors or four sensors. Here are few tips to choose the correct welding helmet which may increase the weld quality, comfort as well as the productivity.
While buying a helmet, the major concerns are viewing size that auto-darkens which is based on your wish and the welding work you do. When your welding applications are light then the viewing size is 6 square inches and for industrial use, it should be 9 square inches.
Auto-Darkening Or Passive Lens
When you select a welding helmet the standard it should meet is ANSI Z87+. This standard approves the independent testing for the lenses for protecting your eyes against harmful rays.
Welding helmet that auto-darkens are available for professionals as well as for hobbyists. When you opt for a welding helmet that auto-darkens you should consider variable or fixed shades.
· Variable shades
If the welding processes are different like TIG, MIG, and Stick or when welding amperage varies or even if the arc brightness varies, your eyes will be protected when a lens with variable shade at the same time the puddle can be viewed perfectly.
· Fixed Shades
When the welding processes are same, with similar material and when the thickness is same with restricted amperage range, you may use the lens which has fixed shade.
A welding helmet with the passive lens will have fixed shade with ultraviolet and infrared coating and a glass that is tinted dark. The helmet with the passive lens is worn in a position facing upwards with respect to the position of the torch, electrode or gun. Before an arc is stroked the helmet is positioned accordingly with a quick flip.
A welding helmet used for hobby level needs two sensors, for the industrial grade, the helmet should have four sensors, for production work you need three sensors and four sensors are used for fabrication or when the work is out of position.
While seeking for a welding helmet, research among various kinds of welding equipment available in the market. You can browse through the net and get the recommendations from salespeople who supply hardware in your locale.
Purchase a welding helmet that would be comfy for your head.
