Auto-Darkening Welding Helmet Do’s and Don’ts

Welding helmets are by far the most effective form of personal protection. From severe infra-red or ultraviolet rays, you can protect your face, eyes, and neck. It also will save you from burning slag or debris.

This type of danger can be avoided with the use of an accurate welding helmet. Some welders will perform better if they wear the correct helmet.

Here are some do’s and don’ts to keep in mind related to auto darkening welding helmet:


  • Always wear your helmet while welding
  • Check to see there are no flammable liquids or gases in the vicinity of you, no matter whether you are wearing welding helmet or not.
  • Make sure there aren’t any cracks in the floor or open windows nearby while wearing helmet and welding where sparks could fall and ignite nearby combustible materials.
  • Relocate any flammable materials to a distance of at least 20 feet from you.


  • There should be no combustible material nearby while welding
  • No one should be allowed in the working area without helmet and permission.
  • Do not allow unsafe electrical cable connections nearby your helmet.
  • Don’t use a hose or welding lead that has been damaged.
  • Use a trained welding or gas cutter and he should wear a helmet, not a novice.
  • Avoid using a bare electrical cable without wearing helmet.

Auto-darkening welding helmets can be found for all levels of welders, from hobbyists to professionals. If you’d prefer an auto-darkening helmet, consider these options:

Variable or fixed shade

The fixed shade auto-darkening helmet that detects an arc will darken to a lasting fixed #10 shade, allowing the user to balance the economics of a fixed shade helmet with the convenience of auto-darkening.

With a limited amperage range, you may want to go with a fixed-shade helmet if you do a lot of welding on the same sort of material and with the same welding system.

With a variable shadow lens, you’ll be able to save your eyesight while still going to get the best perspective of the puddle. Almost all the changeable shade lens adds from the hues #9 through #13.

Lens reaction time

Welding may cause the lens to change from its normal lighting position to a darker shade. It is preferable if the welder has quick eyes.

Entry-level lenses are regarded at 1/3,600 of a sec, whereas professional as well as industrial grade helmets may be rated as high as 1/20,000 of a sec. “The more arcs you start per day, the more you’ll notice the rapidity.

The combined impact of the advanced exposure to arc light could indeed lead to eye fatigue at the final moment of the day if you use the lens rat1/3,600 for more days. The effects may be reduced if the switching speed is increased.

Viewing size

Take into account the size of the helmet if you want to purchase an auto-darkening helmet. If you’re a fan of welding out of position, you can choose how much of it you want to do. Slight-duty size varies from six square inches to nine square inches, with the latter being more common in the industry.

Adjustable delay controls

The ability to adjust the delay time is critical. You can control how long a lens is dark after the welding arc has stopped using this feature. To speed up the process of repositioning for the next weld while tack welding a large project, consider using a short delay.

Helmets with auto-darkening lenses, whether intermediate or advanced, usually allow the user to adjust the brightness of the lens. When the arc isn’t as intelligent as other welding procedures, sensitivity control is especially useful for TIG welding at low amperages.

What is an Aneroid Blood Pressure Monitor? How Does It Work?

Using an aneroid monitor, your blood pressure is manually checked. With a cursor on the dial, you can read its gauge. You inflate the cuff by hand by squeezing a rubber bulb around your upper arm.

It is not uncommon for aneroid monitors to be more affordable than digital monitors. They’re priced anywhere from $20 to $40, depending on the model.

A built-in stethoscope is included in the cuff. We already have one, so no need to purchase a new one. The cuffs can be put on using one hand if the device has that feature. It is also lightweight and portable, making it easy to move from one location to another.

Squeezable rubber bulbs and a gauge for taking blood pressure are all examples of manual devices. It’s necessary to use a medical stethoscope to hear the heartbeat.

The circular dial of the gauge shows your blood pressure as the needle moves and cuff pressure rises or falls.

When used properly, manual devices can be extremely precise. However, they aren’t the best option for people who want to monitor their own blood pressure at home.

How does it work?

A person can aneroid blood pressure monitor use it in the following ways:

  • Listen to what the stethoscope can hear. The ear buds should be positioned so that they face forward and away from your ears.
  • Place the stethoscope disc on your elbow’s inner side.
  • Squeeze the rubber bulb to inflate the cuff. As long as your systolic reading is 30- 40 points higher than the previous reading, you’re good to go. The systolic blood pressure reading is the highest number. Make sure to pump the cuff up quickly rather than slowly. A false reading will be obtained if the cuff is inflated too slowly.
  • Slightly loosen the unit’s valve and slowly release some air from the cuff. Remove 2 to 3 millimeters per second from the cuff. You won’t be able to take your blood pressure reading if you over-loosen the valve.
  • Once the cuff is deflated, you will hear your heart beating as you remove the air. When you hear something, pay close attention. Look at the needle on the dial to see if your blood pressure is within the normal range. This is your systolic pressure or the pressure in your arteries.
  • The cuff should be deflated further. Watch the rhythm of your own heart. At some point, you will hear the heartbeat stop. Take a look at the dial’s display. Your diastolic pressure is measured by this number.
  • Measure it and make a note of it in your book. It is the diastolic pressure that comes first. For instance, a 120/80 ratio
  • Wait 2-3 minutes prior to actually starting the measurement again if you do need to repeat it for any reason.

Tips for monitoring blood pressure

  • To ensure that you are taking your blood pressure correctly, practice using a monitor with the healthcare provider.
  • Your upper arm should be at the level of the heart and your feet should be on the floor so that your arm can be supported.
  • Before taking your blood pressure, sit down and relax for five minutes.
  • Stress, caffeine, or smoking in the last 30 minutes are all reasons not to take your blood pressure. If you’ve recently exercised, don’t take it.

Take at least two readings, one minute apart, in the morning and one minute apart during the evening. For the next five days, measure and record your BP, and then report the findings to your doctor.
