Fixed shade helmet or an auto darkening helmet?

Wednesday, January 18th, 2012

Even though people have used fixed shade helmets forever, the market is swiftly moving towards auto darkening helmets. Prices and performance both are improving. Today, auto-darkening helmets can be bought as low as 39.00 dollars. While not top of the line, they will typically be fairly good performers for average welding. Even name brand, high end companies are offering welding helmets under the 200 dollar mark.

A fixed shade helmet will never be replaced completely. It will probably always be the choice of pipeliners due to the designs available that make their use in the field irreplaceable. But in reality most other jobs can be performed with almost any good quality auto-darkening helmet. For TIG welding, however, more money may need to be spent to obtain the best performance, especially for low amp TIG. These helmets usually have 3 or 4 sensors to pick up the welding arc at different angles. But a few good quality 2 sensors do a fairly good job with TIG in all but the lowest amp ranges.

An important issue for many welders is to decide on the type of auto darkening helmet. There are principally two types: “Solar Powered” and “Battery Powered”. The Solar powered type are a little slower in switching. Some so-called Solar powered units still retain, a permanent, non replaceable battery. These will last for some time, but usually have a service life of 5 years or less. The best are the replaceable battery type which offer easy access to a commonly available battery. Some auto darkening helmets use a triple “A” battery. These are great and easy to replace in a moments notice as the batteries are only a convenience store away.

Fixed shade Auto-darks only offer a shade of 3 or 4 while not activated, and another shade of usually 10 or 11. Other, more advanced helmets offer features such as sensitivity, shade and delay selection. These are usually the best as they allow the most flexibility to fit any work environment.

When selecting between the different helmets, it comes down to budget, and overall comfort. A helmet with a lot of features could be bulky and heavy. A simple, inexpensive helmet may in fact feel better. Try several out before settling on one. Fitting and balance are important whether its fixed or auto darkening.

Tips for arc welding

Wednesday, January 26th, 2011

Introduction:

In industries the arc welding playing the vital roll and it is more helpful in welding industries. Arc welding is used to make the machines in good shape and it works for more years depend upon the usage of the machine. Arc welding is a metallurgical procedure for two metals fusing by intense heat at the moment of fusion of the two metals.

Tips for arc welding basics for beginners:

Safety measures for arc welding:

In the initial stage for starting the welding works the welder should strictly follow some rules and regulations.

1.    Eyes and skin should be fully covered because the UV light is discharging from electrodes while welding.

2.    During arc welding use helmets compulsorily. To prevent the risks. The risks like fire accidents and shocks so the welders have to strictly follow the rules and regulations.

3.     And keep one bucket full of sand, welding helmets and gloves to start welding process.

Rules for arc welding:

Keep the welding machine on and at the moment of welding the welding machine should touch the fusion of the electrical circuit is fulfilled and the electric arc is produced. There are two methods of electric arc is there they are tap starting and scratch starting.

Rules for organizing the joints:

In arc welding while welding the impurities and dirt will be removed and it will modify the transmission. And the welders have to create joints for each arc welding it is more important for arc welding. This is more useful way for avoid some cases like cold joints and it is more helpful in creating the fusion more powerful.

Importance of Welding Helmets and It’s Types

Thursday, January 20th, 2011

A person who is working in the field of welding or just examining the welding process needs to wear a welding helmet .The reason why welding helmets are essential is because of the bright light given off by welding. Without taking safety measures, this light can factually burn the insides of your eyes and cause temporary or permanent blindness. Part of the reason is that mainly in dark places, the eye cannot adjust to the change in brightness fast enough to prevent damage. A good welding helmet not only protects you from rapid sparks, but also shields you from the extremely brilliant welding arc.

Today welding helmets have changed significantly. While they look quite a bit unusual today than they did years ago, you can still find two main types of welding helmet:

  • Passive
  • Auto-dimming

Whenever you picture welding helmets, you’re almost certainly thinking about manual, or passive as it’s also known. The main advantage to these passive helmets is that they often cost less. More recently, auto-dimming welding helmets have become more popular. These helmets, like the conventional manual ones, are a part of metal and a piece of glass. The auto-dimming helmets come in two types, some use infrared viewers whilst others use electricity to dampen the glass. Both use electricity.

Welding helmet- A real boon!!

Friday, January 7th, 2011

Welding is one of the important and hazardous processes used in industries. The sparks generated by the welding processes are very hazardous to the eyes and hands if it comes in direct contact, so it is always necessary to wear proper safety gears to keep the welder free from any danger or injury. One of the best safety gears for a welder is the welding helmet.

As said earlier welding helmet is the primary safety gear for a welding machine operator. A good helmet is outfitted with auto darkening mechanism. This is a feature that enables the operator to view and do the work through the lens that reacts instantly to the arc and darkens to a selected shade level. While welding , the sparks produce a great amount of UV rays and also radiation which is very harmful to the human, so using a proper safety gear will not only protect you from these harmful radiations but also acts as a screen against the flying debris. There are loads of types in welding helmets, so go for the one which is apt for you.

Wednesday, November 17th, 2010

When you have a welding shop, everything is arranged properly, all the tools are kept properly in their respective places. It becomes easy for a welder to work. But if he is out in the field, everything is not arranged as per welder’s requirement which can lead to accident. To protect against accidents while using a portable welder it is important that welder wears protective equipment.

The most obvious danger of welding – whether with an oxyacetylene torch or with a MIG or TIG welding, is the risk of eyes. So the first safety precaution should be protecting your own eyes and eyes of others. The best way to protect your eyes is by wearing welding helmet. Welding helmets come in standard or auto-adjusted versions.

When using portable welders, you have to protect your eyes as well as of others. If you are welding at home or on a farm, you have to protect the eyes of animals as well, who will look at the welding arc and will not understand to look away, and thus experience arc flash. When possible, move animals from the area, if possible set up opaque welding curtains around the work site. Always keep an extra helmet if any of visitors want to talk with you urgently while welding.
