Solar Welding Helmets

Solar Welding Helmets

Welding is a hazardous activity. The welder is exposed to intense light, harmful UV/IR radiation, and spatter.

Hence, a welding helmet is arguably the most important piece of protection. Sensor technology and electronics have made possible the development of the so-called auto-darkening systems.

A welding helmet with auto-darkening is quite practical. By default, the lens is clear in what is commonly referred to as the “grinding mode.”

When you weld, several sensors detect the presence of an arc and associated intense light and radiation. This activates the electronic control of the lens, which turns dark to offer adequate protection. When the welding ceases, the lens automatically goes back to the grinding mode.

This increases time-efficiency since the welder doesn’t have to manually flip the lens up and down. High-end welding helmets with auto-darkening can shift from grinding mode to dark in a very short time.

This is referred to as the reaction time. Generally, the time to go from dark to grinding mode after welding is adjustable.

To function, this type of helmet needs a DC power source. The most obvious solution is to use batteries. And batteries were used initially.

The problem is that you need to change batteries often if you weld for several hours a day. This is the case of professional welders.

To tackle the problem of batteries, manufacturers started incorporating photovoltaic cells into this type of welding helmet. This is how the so-called solar welding helmets were born.

How does this technology help extend battery life? Is it convenient to invest in this type of helmet? Read on to find the answers to all these questions.

Exhaust Clamps vs. Welding: Which Method Should You Use?

Exhaust Clamps vs. Welding: Which Method Should You Use?

Internal combustion engines need an exhaust system to get rid of the resulting gases from the combustion.

Such a system consists of different pipes, including a muffler that helps to reduce noise. Your car has an exhaust system designed to prolong the life of the engine and boost its performance.

For upgrades, maintenance, or repairs, some pieces of the exhaust system need to be replaced sometimes. A common argument is whether one should use exhaust clamps or welding to fix these parts.

Some argue that exhaust clamps are more practical, whereas others prefer welding. Which method should you use?

To help you decide, we will discuss the differences between exhaust clamps and welding in this article. You will learn about the different types of clamps that you can use, as well as different welding techniques.

Are you ready to make a more informed decision? Then, read on.

Flux Core Welding vs. MIG. What Type of Welding is the Most Convenient?

Flux Core Welding vs. MIG
Flux Core Welding vs. MIG

Professional welders often argue on which type of welding is the most convenient for a certain application. It is the case of flux core welding versus MIG.

Both welding types have some similarities and differences, which argue in favor and against each of these welding types.

The truth is that, in general terms, no method can be considered absolutely better than the other.

You have to take into account some specific characteristics of the work that you’ll perform. What will you weld? Where? What finish do you intend to get after welding?

Hence, the most important thing is to learn about the conditions under which each type of welding will provide better results.

In this article, we aim to inform you about the essential criteria to determine which type of welding will be more suitable for your particular case.

Auto Darkening Welding Helmet: How It Works

Auto Darkening Welding Helmet: How It Works

Welding produces intense light, radiation and heat. Thus, welders must protect themselves through the use of welding helmets.

With a common helmet, a welder has to flip the lens up to see the result of the welding. It is highly inefficient, particularly for professional welders.

Luckily, technology has developed welding helmets with a so-called auto-darkening feature. This type of helmet shifts automatically from a shade level 3 (grinding mode) to a darker shade when welding.

Several sensors on the helmet detect the presence of an arc, thereby activating the auto-darkening system. How does all this work? Find out in this article.

6011 Vs 6013 Welding Rods: Similarities and Differences for Precise Use

6011 VS 6013 Welding Rods
6011 vs 6013 Welding Rods

Arc welding requires electrodes/welding rods to work.

It’s responsible for electricity passage to the base metal and eventual fusion. The electric arc created by the process reaches 5,000°C (9032 F).

These rods are of different types and serve different purposes. A proper electrode should be chosen, in order to make sure the result satisfies.

It’s recommended to use mild steel electrodes approved by AWS (American Welding Society), but there are thousands of them, so you have to choose the right type. 

6011 and 6013 rods are similar, but the precision will only be achieved if you use them in proper applications. Here, we will discuss all the similarities and differences between the two and see if any of them are a better option.

How to Change The Battery in Welding Helmets

How to Change The Battery in Welding Helmets (1)

A welding helmet, or a “hood”, is one of the most important safety equipment for any welder. These days, most welders are using auto-darkening welding helmets that darken or lighten depending on the task.

It’s a very neat feature that makes welding a lot easier, but it does mean that sooner or later, you’re going to have to change the batteries. 

If you don’t know how to change the battery in a welding helmet, don’t worry, we can walk you through this simple task. In this step-by-step guide, we’ll explain to you how to do it.

Stick vs. MIG Welding: Choose the Right One for Your Application

Stick vs MIG welding
Stick vs MIG welding

Welding techniques have evolved significantly in the last decades. Nowadays, a professional welder has different options to choose from.

Depending on the particular requirement of a procedure, one or another technique may be more suitable.

In the past, stick welding was the only option available.

It remains one of the most used welding techniques, but the improvement of electrical technology led to the development of some alternatives. That’s the case of the so-called MIG welding.

Hence, a professional welder must be acquainted with the characteristics of each of these techniques. Knowing their pros and cons will help you decide which technique to favor for a given situation.

Hence, in this article, we will compare Stick and MIG welding techniques.
