For lower amperage work with MIG and TIG, you can use a lower shade lens so as the weld puddle remains easily visible. As a general rule heavy welds will require a higher shade lens as the currents are higher. View size, there are several here with the larger being 3.82 x 2.44 inches (97x 62 mm) Most Auto Welding helmet lenses available have settings that can switch between between the different shade ranges, providing shades from 6 to 9 or 9 to 13. Some models, with smaller view sizes and more compact shells, are approaching weights as low as 15-13 ounces.Next opt for full cover shells that will safely protect from sparks, grinding and weld splatter, also check that the helmet is capable of unexpected impact. Many new helmets can weigh only 18 to 21 ounces ( 602 grams, even with a full-coverage shell.
Wearing a helmet all day is no fun if its overly heavy or has poor head mountings.
This type of helmet is a must for continuous stop start welds used in production work, less stressful on the welder and more productive.
This not only is a more safer approach but also allows greater accuracy and neatness of the weld. The benefit of this type of helmet is that the welder is able to accurately see the area to be welded before striking an arc, as the lens is clear until the arc is struck. New technology using liquid crystal displays, (LCD) can darken the lens in milliseconds giving the welder utmost protection from the harmful welding rays. the best of these offer variable controls that can be adjusted to suit the shade required. lenses are available in different colors, the most popular being green, gold or blue.Īdvanced welding helmet lenses are to be found on auto darkening helmets. The light properties of the lens depends on the welding type being used, the welder current and material being welded. Welding helmet lenses are available in a variety of optical densities that are designed to filter intensity of light produced by the arc. Welding helmet lenses are to protect the welder from eye damage and flash burns.
