The most common way welders do this is by running the lens under hot water. Before you do this, you need to place a couple of drops of detergent on the lens to help lift the abrasive materials off. I found it easier to fill a spray bottle with hand soap and water to spray the lens.

In respect to this, what shade of lens should be worn when welding?

Welding lens shade numbers refer to the lens' ability to filter light¾all auto-darkening welding helmets meeting ANSI Z87.1 provide 100% protection against harmful infrared and UV rays¾ and may range from a #8 shade for low-amp applications up to a #13 shade for high-amp applications.

Subsequently, question is, what is the best way to clean aluminum for welding? Take the following steps before welding aluminum: 1. Remove oil, grease, and water vapor using an organic solvent such as acetone or a mild alkaline solution like a strong soap. You may also use citrus-based degreasers, but be sure to rinse and dry the part before welding.

Just so, how often should I change my welding lens?

Typically, you should only need to replace it once a month, though again this will vary from welder to welder. Put simply, the lens should be replaced whenever it incurs damage or when visibility starts to decrease.

Are all welding helmets the same?

When work is complete, the welder has to lift the helmet to see. However, if most of your welding tasks only involve one kind of material, at the same thickness, and if you're always using the same process at a fixed amperage, then there's really no need to buy anything more than a fixed shade #10 standard helmet.

How dark should a welding helmet be?

It's recommended that you use between a shade 10 to a shade 13 welding lens to prevent flash burn on your eyes. The higher the number the darker the shade will be. However, the more amperage you are using the darker the shade you will want to have to avoid burning your eyes.

What is the darkest welding lens?

Green Shade 14 Solar Eclipse Glasses. #14 is the darkest lens shade you can buy – just as dark as the most protective welding helmet shades. As a result, these glasses are so dark that you can wear them to watch a solar eclipse, as well as using them for all types of welding including MIG and TIG.

Can a cutting torch burn your eyes?

So yes the torch can damage the eyes, it just takes longer.

Do you need a welding mask for brazing?


A full facemask may be required for arc welding. Welding and cutting processes, including arc welding and cutting, as well as brazing produce intense ultraviolet (UV), infrared (IR) and visible light wavelengths.

Why are welding goggles green?

UV and IR are very harmful and are what cause "welder's flash" and damage to your eyes. Every auto-darkening welding lens has a purple coating, this is a UV/IR filter and it blocks out UV/IR light. The blue and red ends of the light spectrum are blocked. This is why everything appears green through a welding lens.

Can you weld with shade 5 glasses?

Best Shade 5 Welding Glasses
They're only a shade 5 so aren't suitable for you MIG/TIG welding but work great for when you're cutting with a torch or grinding metals. One of the things I like about these is that they're a lot more comfortable than many other safety glasses or welding goggles.

What harmful light is produced during welding?

Welding arcs and flames emit intense visible, ultraviolet, and infrared radiation. UV radiation in a welding arc will burn unprotected skin just like UV radiation in sunlight. This hazard is true for direct exposure to UV radiation as well as radiation that is reflected from metal surfaces, walls, and ceilings.

How long do welding helmets last?

The lifespan of the non-replaceable battery is approximately 7 years, its disadvantage is that once the battery wears off, the lens doesn't work. The auto darkening helmet with a replaceable battery and solar assist is a better investment because the panel allows you to start welding right away.

How do you clean auto darkening lenses?


Start by smoothing the lens with a soft bristled brush. This will also take any dust off your lens. After going over your lens with a soft bristled brush, examine how dirty your lens is. If you regularly clean your lens, or it just isn't that dirty, then you can get away with only using water to clean it.

How do you clean a welding mask?

How to Clean a Welding Helmet
  1. Take Care of Your Helmet. Welding will cause smoke, debris, and scratches to mar the view through your helmet.
  2. Clean With Detergent. Remove the cover lens from your helmet.
  3. Buff It Out. You can always use your buffing wheel to remove the toughest dings and scratches.
  4. Use a Welding Service.

Is acetone good for cleaning metal?

Acetone is a common industrial solvent used to clean metal surfaces prior to welding. It effectively removes dirt, grease and staining from metals which allows for a better, and sometimes stronger, weld.

How do you prepare Aluminium for welding?

To summarize, take the following steps before welding aluminum:
  1. Remove oil, grease, and water vapor using a solvent or mild alkaline.
  2. Remove surface oxides with a wire brush or strong alkaline or acid.
  3. Assemble the joint.
  4. Keep the joint dry.
  5. Weld within a few days.

Is acetone good for cleaning aluminum?

Acetone is fine. Lacquer thinner is a step back from acetone; not quite as aggressive but works well for cleaning most anything gooey. Both evaporate completely, leaving no residue. Neither will penetrate, stain or otherwise damage aluminum.

What do you clean metal with before welding?


First you must wipe down the metal with Low VOC PRE or acetone, this will remove any oils or grease on the surface. The next step is to remove any oxides on the surface of the metal. To do this use stainless steel wool or a stainless wire brush on the area to be welded.

What can clean aluminum?

To clean aluminum, start by using a mild dish soap and water to remove major debris. If your aluminum has oxidized, make a cleaning solution by mixing lemon juice, cream of tartar, or vinegar, with some water. To remove rust from aluminum pans or utencils, for example, mix 2 tbsp of lemon juice with 1 quart of water.

Can you weld painted aluminum?

High-speed brushing can burnish or imbed oxidation into the aluminum. Aluminum is a great conductor of heat. So nearby paint will burn off, causing smoke, which can pollute the shielding gas and deposit hydrogen into the weld. With a MIG welder, use an aluminum filler wire that is 3∕64 or 1/16-inch in diameter.
