Advantages Of Opting For An AC DC Welder

Thursday, May 21st, 2009

Our world, as we know it today, is literally welded together by welding machines. Welding is the cheapest and most effective method to bind two metals together without any loss of strength or weakness in the bind.

Your business will gain a lot by adding an AC DC Welder to the welding equipment that you already own. Some of the advantages are listed below

- Better value for money

Buying an AC DC Welder along with your other welding machines will increase your ability to provide better value for money to your customers. This welding equipment is usually available as a portable machine and this enables you to provide different services on the go.

- Versatility

The range of services that you can provide drastically increases if you opt for the portable AC DC welder. You can now undertake maintenance work, repair work, fabrication work, construction and erection work and hard surface work including cutting and piercing holes in steel

What is a DC Welder?

Tuesday, February 24th, 2009

The DC welder is perfect anytime you may need high performance and durability, in a welder. This welder equipment comes equipped with a great arc welding power supply , cables and plug. These machines come with the ability to change from AC (alternate)/DC (direct) power output options. This is great depending on the type of power options available and your ‘be ready’ status for working.

They can be installed and ready to go within minutes due to their compactness in their size and easy to handle capabilities. It is easy to store because its compact in size. But, when it comes to performance it is not tiny in its feat, the DC welder will deliver a strong powerful stream of power to its weld.

This machinery is flexible in its welding output to aid your stick welding capabilities. This versatility is an awesome feature to have when your job may differ from the largest to smallest and you can rely on a steady stream of power for all ranges. Each weld job may or may not need the same source material or even the same electrode types so it is great to have a machine that is ready to go no matter the job.

The DC welder can deliver a smooth arc for your weld needs. The electric arc is unique for each job and will differ on the size and type of the electrodes. The arc is a major part of the welding procedure and will have an effect on the quality of the work or performance of the job. The electricity flows from the power supply which is the workhorse for the task. The power supply flows in the desired current to the electrode and the electrodes actual disintegrate and protect the weld surface, while they expel the shielding gas. The shielding gas vaporizes as it forms a shield around the meld surface to protect from damage and create a quality finish. The finish is the sought after manufactured good and should be of a great quality depending on the craftsmanship of the worker and the welding equipment.

There are the AC/DC welding machines that will allow the versatility between the types of arc needed. The DC welding arc can be called the arc type you would need when you are in need of a more stable flow. The AC welding switch would be the choice if you have a larger electrode and need faster travel speed rates, as well.

This machine can deliver when it comes to the average needs of any stick welding job or task. Use a DC welder when you have welding jobs that could vary in size and types, because I am sure it will meet the challenge.

The Basics of the Arc Welder

Thursday, February 12th, 2009

This is an article on the basics of Arc welding and its equipment. Arc Welding occurs when powerful heat starts to melt the metal, this causes an electric arc. The arc will appear at the point of contact between the metal and the electrode or stick, manually placed along the joint. The electrode is a rod or wire used to carry the electricity to the material being worked.

Within the Arc Welding procedure, there are four basic components that create the arc. You would need the power supply or arc welding circuit to bring power to the source of the equipment and the work could not be done without it. This power runs from the circuit through a cable and into the electrode holder. The electrode holder directs the electrode or stick onto the material being welded or worked. It is when the electrode makes contact with the material along with the electricity that causes the arc. The arc or visible light that flickers when the welder begins to mold his pieces.

Now that you are familiar with the procedure of Arc Welding, let’s get more acquainted with the equipment and their features. The Arc Welder equipment is very powerful and needs current from a power source.

The current is the most viable component to the entire process, so having the option of portable power supply units come in handy. If you are in need of higher voltage there are some welders that come with larger and more powerful units. Most circuits have the duality in that they offer both AC (alternate current)/DC (direct current) power. It is said that most DC outputs are better at constructing visual welds.

The electrode holder transfers the electricity from the circuit to the electrode or rod, enabling the current to flow to the material/metals to be worked on.

The electrode or rod delivers the heat to the site, melting the metal with the aid of fillers while creating a gaseous protective shield. There are other components needed within the arc shielding process such as the slag. The slag or molten metal along with the vapors are used to protect the metals from the air. When the air hits the metal in its weakened state it will damage or weaken the joints. The overall process called arc shielding may protect and even improve the welder’s work.

The process of arc welding itself is highly scientific and takes someone with finesse in craftsmanship to produce a great product. If you are looking for Arc Welder to buy, it is my advice to buy one with duality in power output. If you get a portable or heavy duty says something about the size of the job, but most will agree that they love the rugged durability of an Arc Welder.

Types of Welding

Sunday, January 4th, 2009

Welding is still a very important part of work today. The auto industry, the military and many other industries use welding to bring together metals. Welding takes two pieces of metal and melts them so they can be bonded together.  There are many different types of welding but arc welding remains the most popular.

Welding actually dates back to ancient times and people have found evidence that it goes back to the Bronze Age. In ancient Egypt evidence of welding tools were found that date back at least 1000 years.

When the joints of metals are melted together they make a strong bond. This is necessary in many cases to make sure that products like automobiles will stay together when they are driving down the road.

The type of welding that is used will depend on the situation and the material being used. Most will use some type of torch that uses gas or electricity to make the weld. Some of the major types of welding and how they are done are listed here:

Propane torches
— usually these are used when people have a smaller project to do. It is used to solder two types of metal together or when they want to sweat the joint. Jewelers often use this method when they are joining small pieces of metal in jewelry making.

Oxyacetylene torch– this torch is a step up from propane because it gets hotter and you can use it for larger projects. It is used when a very hot flame is needed. When a welder wants to braze, cut, solder or weld metals that require a very high heat to melt, they use this type of welding.

AC & DC Arc welders
– this kind of welding is used for heavier gauged steel or when a project is using cast iron. Rods of flux coated steel or varied materials are fed through the welder unit and these are guided into the joint that is to be welded.

MIG also known as Metal Inert Gas
— some welders prefer this form of welding because it is easier than other types of arc welding. A DC arc is used with a reel of thin wire. To make the weld, filler material is used and an inert gas is used to make the bond instead of flux.

Welding is a skill that many people possess and there is always a need for it.
