The Best Welding Helmet Buying Guide
A welding helmet is of daily use to anyone who earns a livelihood through wielding. The best ones have an element of sensitivity and delay feature, lightweight, have upto 3 or 4 arc sensors, normally adjustable from shades 9 – 12 and have a response time of about 1/20,000 a second.
A more costly welding helmet while ensuring one’s safety is effective in producing high quality welds. This results from welding performance support and the operators comfort. However, for an operator that is unfamiliar with safety standards and the most recent auto-darkening optical technology, it can get confusing in deciding on the best welding helmet.
Prior to investing in this safety gear, this guides helps in the selection procedure with important considerations. A welding helmet with lens that is most suitable is usually the one to go with. However helmets are either of the following types:
- Standard or Passive Welding Helmets
- Auto Darkening Welding Helmets
- Fixed Shade or Variable Helmets
- Professional and Intermediate Level Helmets
- Battery and Solar Powered Helmets
Standard or passive welding helmet types are just as popular as they were a long time before. These helmets are offered at reduced prices since they are created from moulded plastics instead of thick leather. The filter or viewing lens has infrared and ultraviolet coatings. In most instances, a number 10 shade is offered.
Light reactive referred to as auto-darkening welding helmets, resolve problems such as maintaining correct gun/torch position, manoeuvring the helmet, neck discomfort and impractical during tact welding. To make the welding experience easy, these helmets are equipped with an adjustable electronic lens filter. The welding arc is detected by a few light sensors near the lens. This makes it possible to see through just like the sunglass shade.
For welding utilizing a similar process e.g. MMA, with the same amperage for just one kind of material like steel, of the same depth, here a fixed lens shade number 10 is required. Fixed shade glass lens helmets are apparently standard. Fixed shades are usually offered in quite a few inexpensive auto-darkening helmets too.
Generally, an adjustment control is the feature of professional and intermediate level auto-darkening helmets. The amount of intensity triggers the lens to grow dim. While welding at lower amperages, where the arc is not brighter than most other welding processes like TIG, sensitivity control is useful.
Quite a few auto-darkening welding helmets have an in-built solar assistant panel and a non-disposable lithium battery. Prior to its use, these helmets are very often required to be charged through sunlight. Moreover, if stored for longer durations, they require the same charging time. However, when required to weld right away, this poses a real nuisance.
On the whole, manufactures publicize lens switching speed, in relation to auto-darkening helmets. As soon as the welding starts, the lens switches from its natural light condition normally a number 4 shade to a darker shade. The number indicates the speed of this switch. Moreover, the faster a welder’s eyes are protected from the glare of the high-powered light, there’s no arc eye (dry scratchy feeling).
