Welding Shade Chart

Welding Shade Chart - Welding is a risky profession and safety is the top priority.

Within your arsenal of security tools, a high-quality auto-darkening welding headgear is the most crucial product - and with reasons that are well-founded.

Welding Shade Chart

A welding helmet's purpose is to shield you from radioactive radiation (ultraviolet as well as infrared) as well as spatter and sparks and a host of other risks that can be found within the workplace of a welding worker.

There are around 10,000 eye injuries due to welding every calendar year (U.S. Consumer Product Safety Commission) So a choosing a suitable helmet is vital.

This guide will help you select the best helmet for your requirements.


Fixed Vs. Variable Shade Lenses

The first thing you'll need to make is choosing between a variable and fixed-shade lens.

Fixed-shade helmets are able to be darkened to a single shade, which is pre-defined (usually a shade #10) however, helmets with variable shades may darken to a variety of shades, dependent on the welding procedure employed and the materials that are being welded.

The final decision is dependent on what your flexibility in welding requirements will be.

If you're planning on welding only one piece of material with a single procedure in which case a fixed-shade would suffice.

If however you'd prefer being more flexible in the welding materials and the welding techniques you're employing A variable shade is the right choice.


Lens Reaction Time Chart


Simply put, this is the time that it takes for an image to get darker or change, from the normal light (usually the #3 and #4) in order to switch to the safer, darker shade.

The darkening begins when the weld ignites.

It should occur extremely quickly so as to shield the eyes from contact with radiation.

If there is a tiny delay, the subsequent exposure can cause irritation and dry eye which is also known as 'arc eyes'.

After a long period of exposure, significant damage can be caused to the eye.

As a general rule The simplest helmets will be able to react in the range of 1/3600 of a second and the more durable models will reach speeds of 1/20000 of one second. 

For clarity The larger the fractional value greater, the more rapid the lens reaction time.


Arc Sensors

As you've likely guessed, ADF helmets sport a array of sensors that are able to detect the spark that is generated by welding that triggers the process of darkening.

The position, number and sensitiveness that these devices have are vital to ensure that the helmet is aware of illumination levels at all times and also darkens as it's intended to.

The main difference between basic helmets and the professional models is usually the amount of sensors for arcs Basic helmets typically include two sensors, while those with more experience contain 3 or 4 sensors.

It is not surprising that the more arc sensors there are on your helmet, there is lower chances of it not getting dark at the right time.

This is mostly due to the higher number of sensors there are, the less possibility of them all being blocked.

Usually, two sensors will suffice, but in the case of more welding out of position, then more sensors are definitely beneficial.

Welding helmets are often equipped either with magnifying lenses, and "cheaters". 

You can purchase lenses that be clipped to the helmet or wear corrective lenses underneath your helmet.

If you decide to use an option, select the one with the lowest diopter, which allows you to clearly. 

If you're under 40, the standard is +1.75 and people aged 40and over choosing the higher diopter.


Solar Power VS Battery Power

All ADF helmets require some kind of power source.

This typically takes forms of solar power panels , batteries (usually lithium) or a mix of both.

The life span of solar-powered batteries is typically measured in years that is far more than the battery-powered counterparts.

They're also less expensive in the long run since you don't need to invest cash on new batteries.

However battery-powered helmets do not require any planning unlike solar-powered helmets which require several hours under the sun prior to when they are able to be used, helmets powered by batteries can be utilized immediately.

When solar-powered helmets are depleted of energy, they have to be recharged once more: the process could take up to a couple of hours.

The best option is an array of solar-powered battery-powered helmets.

This source of power combines the most efficient of both worlds: the capability to charge battery cells using solar panels, aswell being able to change batteries at any time when needed.

Auto-darkening headgear has many advantages including automatic darkening when welding.

Even if the electronics fail, they offer basic levels of safety (ANSI Standard). 

Auto-darkening helmets are available with fixed or variable shades.


A Few Final Points Of Consideration

The weight of the helmet is a key factor for comfort and shouldn't be overlooked.

As you'll wear the helmet for long periods of time it is important to make sure that it's not overly heavy, because even a small amount, during a long day of work, can begin to weigh you down.

This is especially the case for helmets with passive features that have to "head nodded" up and down throughout the day.

ADF helmet wearers can also be impacted over time.

The comfort factor is crucial when you selecting a helmet.

Make sure you try the helmet it, adjust the straps, and ensure that the helmet fits well but not too tight.

Be sure that the headband is high-quality and is well-fitting it's job is to wick sweat away and is crucial in the hot and often humid welding atmosphere.

As you will observe, there are many aspects to consider when buying a welding helmet.

Think carefully about the welding area you are in and choose a helmet that is suitable for your requirements.

If you've done a great task, then your safety helmet will last for many years and your security is guaranteed.
