    What's New — Speedglas Adflo

    We love hearing from our customers...

    Dear Manager,

    I'm a mother of a FIFO boilermaker and wanted to write to thank you for the great service which I received from Troy?? when he answered my enquiry on Tuesday.

    My son had been trying to get a part for his welding helmet from a local supplier for 5 months and each time he arrived home (FIFO), they had the wrong part. He was having to duck-tape the hose on his helmet when working in confined spaces in the Pilbara.

    Within two minutes of my phone call to Eweld, the salesman had provided the part number, gave me directions to the website and how to navigate it and advised that I could also order over the phone. The part was on its way within the hour.

    I texted my son to let him know I had received the part today and he was blown away that it only took 2 days to Canberra !! ( he flys home on Tuesday)

    I wanted to let you know that your service was absolutely outstanding and THANKYOU!

    Warm Regards
    TD of Queanbeyan

    The New Adflo Powered Air Respirator System

    The Upgraded 3M™ Adflo™ Powered Air Respirator - Super Light & Rapid Charge

     

    The upgraded Adflo™ Powered Air Respirator has been reduced in weight by over 15%. The new Adflo lithium-ion batteries (standard & heavy duty) charge from 0 to 80% of their full capacity in approximately one hour.

     

     

    Hot Working Conditions

     

    With its smart, compact design, the award-winning Adflo Powered Air Respirator is specially designed to meet your welding needs when used with the 3M™ Speedglas™ Welding Helmet 9100 Air, 3M™ Speedglas™ Welding Helmet 9100 FX Air and 3M™ Speedglas™ Welding Helmet 9100 MP Air. Its continuous airflow provides filtered air that takes much of the heat and sweat out of welding. By using the Adflo respirator, you get both increased protection and comfort all day long.

     

    An Adaptable System that Saves Money

     

    With the right type of filter, the Adflo respirator effectively protects against both particles and gases. Because you can selectively replace either the particle or the gas filter as needed: you don’t need to change both filters at the same time.

     

    Full mobility with adaptability

     

    The slim profile is perfect for use in tight spaces. Its ergonomics are based on the welder´s need for lightweight, adaptable and easy-to-use respiratory protection.

     

    Constant Flow of Clean Air

     

    The airflow is always a constant nominal rate of 170 litres per minute, regardless of the battery’s charge or the particle loading of the filter. For hot, humid jobs, you can increase the airflow to 200 litres per minute by simply pushing the ON button a second time. The Adflo complies to Australian and New Zealand standard AS/NZS1716 for powered air respirators and delivers a Required Minimum Protection Factor (RMPF) of 50 for mechanically and thermally generated particles.

    Welding Respiratory Protection Guide

    We've dug up this welding respiratory protection guide and thought it might come in handy!! Simply identify the material to be welded and the welding process that will be undertaken. The concentration level of the pollutants are affected by the ventilation conditions in the workplace. Choose the appropriate description of the working environment to determine the most suitable type of respiratory protection.

    Helmet Welding: A common misconception

    Do five wheels make a car go faster??? 

    If having more wheels made a car faster, safer or handle better, then one could reasonably expect that every car would come standard with five, six or even ten wheels. In reality though, we all know that a car only requires four wheels to perform at its best.

     

    The positioning of the four wheels on a car is also extremely important. For example, if a car manufacturer positioned all four wheels on one side, it wouldn’t do much good would it?

     

    Photo sensors on a welding helmet are much like wheels on a car.

    More does not necessarily equal better.

     

    Photo sensors detect the light from the arc and trigger the lens to darken. In circumstances or applications where the arc emits less light and becomes more stable (eg. TIG welding) the need for more sensitive sensor technology becomes increasingly important. Having more sensors does not make a welding lens more sensitive in the same way as having five wheels on a car does not make it any faster. So how do you determine how sensitive a welding lens is? All auto-darkening welding helmets have a sensitivity rating - the 3M Speedglas Welding Helmet 9100 has the best rating possible (rated for use down to 1 Amp).

    Position is extremely important.

     

    If a photo sensor is obstructed from viewing the arc it will not react. So maybe having more is better i.e. less chance of all sensors being obstructed? Incorrect. Like all four wheels being on the same side of a car, position is everything.

     

    Have a look at the welding lens below:  

     

     

     

     

     

     

     

    Through the lens you can see that the welder is TIG welding, which as you know requires both hands. Now, if you look at the Speedglas welding helmet 9100 below and take note of where the photo sensors are positioned you will see that when TIG welding, both side sensors may well be blocked and only the centre sensor will be left clear to view the arc.

    So it wouldn’t matter if you had ten sensors on the side of the lens, the important factor is that you have one in the centre.

     

    Therefore, the question isn’t "how many sensors does a welding helmet have"?

     

    The questions should be:

     

    How sensitive are the photo sensors (eg. rated down to 1 Amp)?

    Where are the photo sensors positioned?

     

    Understanding Welding Fume

    WITH the correct PPE, arc welding mild steel in an outside area, or in a well ventilated workshop, is not a problem, but when welding more exotic materials that's when fabricators and co-workers should take special care.

    Arc welding fumes contain very small particles from the consumables base metal and base metal coating.

    The substances in the fumes change depending on what is in the electrode and the base metal including any coatings.

    The most common compounds in the fumes when welding mild steel, for example, are complex oxides of iron, manganese and silicon.

    The short term effects of these compounds, if inhaled, are temporary and include burning eyes and skin, dizziness, nausea and fever.

    However long term exposure to these fumes can lead to silicosis (iron deposits of the lungs), bronchitis, and even lung fibrosis has been reported.

    And if the compounds found in the welding fumes includes Barium, symptoms may include severe stomach pains, slow pulse rate, convulsions, muscular spasms and even death.

    Welding equipment manufacturers and industry organisations highlight the need for fabricators, and their co-workers, to be especially careful when working with new metals and materials, particularly when welding heavy metals such as magnesium and chromium. 

    Welding professionals should understand that it all depends on the base material and the consumable the welder is using and if the metal is coated. It is not uncommon for welders to be overcome with paint fumes when welding painted metal.

    Thankfully, most welders are aware of the dangers of welding fumes, and the short term and long term respiratory problems they can cause.

    For example the vast majority of welding machines and consumables in Australia have warning labels on them regarding welding fumes.

    However, welders should be especially aware of working with exotic materials such as cadmium, chromium, cobalt, copper, fluorides, manganese, nickel, silica and zinc, even stainless steel.

    Fumes from the following metals can cause:

    CADMIUM requires extra precautions, especially as it is often found on steel and steel fasteners as a plating or in silver solder. Cadmium fumes can be fatal, even after brief over-exposure.

    CHROMIUM poses a cancer risk. Stainless steel and other hard coatings contains chromium and can cause lung cancer and asthma.

    COBALT may cause respiratory diseases and pulmonary sensitising, and in metallic form it has been know to cause lung damage.

    COPPER may cause metal fume fever, skin irritation and discolouration of the skin and hair.

    MAGNESIUM may affect the central nervous system, difficulty in speaking, and arm and leg tremors, often non-reversible.

    NICKEL may cause cancer.

    SILICA may cause silicosis.

    ZINC, found in galvanising, may cause fume fever.

    Sasanka Sinha, Technical Manager with WTIA (Welding Technology Institute of Australia) says most welders are aware of the need to wear some form of PPE (Personal Protective Equipment) when welding, "but it's not always obvious how dangerous these fumes actually are when welding different materials.

    "Problems can arise when welders take on a new job or a new material to be welded. Sometimes they are not aware what the fumes contain, especially with Stainless Steel.

    "Galvanised or coated materials can also cause problems, it depends on the thickness of the zinc used when galvanising.

    "If the thickness of the galvanising changes from thin to thick, without the welder being aware, that can cause problems," Sinha told Manufacturers' Monthly.

    Protection from fumes

    Sinha's advice for welders is to use their common sense.

    In Australia, welders are very good, they know their job and are aware of the dangers of welding fumes. They know what PPEs they must use.

    "It's the responsibility of management to make sure they wear the correct PPE.

    "Some welding helmets, for example, have their own extractor, so the dangerous welding fumes can be extracted right at the welding arc.

    "And if the welder is operating inside a confined space such as in a tank, boiler, or pressure vessel, it is the responsibility of the supervisor to provide fresh air and extraction.

    "It is also mandatory the welder has a 'fire-watcher' outside to ensure the welder is not overcome by fumes," Sinha said.

    However, most welders know that wherever they are they should wear PPEs such as breather masks and use some form of ventilation.

    The first option is to ventilate the whole environment. This could take the form of open windows and doors in the workshop so they get cross ventilation.

    Then there are fans and suction devices that manufacturers can use, through to fume extraction arms and hoods, and downdraft tables through to fully engineered systems.

    The key is to get the point of extraction as close as possible to where the welder is operating.

    The goal is for the welder not to breathe any welding fumes at all, so manufacturers should remove as many of the fumes from the workplace as possible. 

    There are a wide range of options available, depending on the location and the metals being welded.
