Plasma Welding Machines

Plasma welding machines are used for plasma arc welding or PAW, as it is popularly called. Plasma arc welding is an advanced version of the tungsten inert gas (TIG) welding process. Plasma welding machines enable performing high quality welding due to the use of high tech plasma welding systems.

Unlike TIG-welding torches, Plasma welding machines feature a constricting nozzle that enables two separate gas flows giving rise to a concentrated plasma arc having a narrow columnar shape. Additionally, the plasma column generated by the plasma welding machine is stabilized along the axis of the electrode and is much more intense than the TIG-welding arc.

Plasma welding machines offer much better quality of welding with lesser sensitivity to any changes in the arc length. Plasma welding machines require much less weld time and therefore result in less brittle welds due to carbides and other complex compounds.

If you're thinking about buying a welding machine for an arc welding process, you would do well to choose plasma welding machines from a reputed manufacturer that offers plasma welding machines that have been thoroughly tested and backed by some kind of performance guarantee. A plasma welding machine will be a good acquisition for your welding business.

You will find several different models of plasma welding machines from various plasma welding machines manufacturers in the market these days. You must conduct thorough research and choose plasma welding machines suited to your budget and the welding requirements of your business so as to save money and get better welding results.

Welding equipment

There are different kinds of welding equipment used in the process of welding. Welding is a process that is used to cut or join different kinds of metals. At different levels of welding processes different kinds of equipments are used. Welding equipments are usually classified into two categories - hand and power driven.

Grinder and hammer are the most essential of all welding tools as no welder can justify his work without them. A grinding tool is multipurpose equipment that functions as per the kind of grinding wheel being used. Hammers are used to align the edges of metals before they are weld. Hammers are also used for various other purposes.

While talking about welding equipments one has to enlist welding machine as the most important tool required for doing the job efficiently in a short span of time. There are different kinds of welding machines available these days for different purposes. These machines operate on electricity.

For welding there are many welding products that are used during the process of welding. These products can be classified as anti-spatter and MIG tools. An Anti-spatter is used to create an outline on metal that debars spatter to stick to the surface of the metal. A MIG tool is used in MIG welding process that stops fusion of MIG wire.

Apart from above listed welding equipments; there are many other kinds of welding equipments as well. These equipments are used to clean up weld and deal with safety of welding processes.

Welding Equipment

The concept of joining metals and making them productive is quite old. The process of joining metals using different sources such as gas flame, electric arc or laser etc. is known as welding.

In ancient times, welding was done through a process known as forge welding, this method involves heating up of the metal to be fixed together and then hammering them till the time they integrate to the desired object or tool. With the passing span of time and technological innovations the concept of welding has seen a tremendous growth technically and today there are various types of Welding Equipment available specifically designed for versatile purposes.

The job of any welding equipment is to make the work easy. Therefore, it is very essential to understand your requirements and then opt for the equipment of your choice. For instance arc welding equipment is specially designed to use electric current to perform the job whereas gas welding equipment use gases like natural gas, hydrogen, propane etc. depending upon the kind of work that is required. Some other specific welding equipment for high end welding processes like resistance welding and laser welding are also available.

There are numerous companies that offer welding equipment for sale. People who are professionally in the business of welding, buying these welding equipments is a good investment as they are durable and are cost effective in the longer run. For other once in a while purposes these can be taken on rent.

Electromechanical Influence Of Welding Machines

In industrial environment, welding refers to a production procedure that joins materials such as metals and thermoplastics. This is typically done by softening the work pieces and adding a filler material, which is often a welding rod, to form a pool of molten material that cools to become a strong joint. Various processes, energy sources and welding machines are used for welding.

Welding equipments and machineries can be generally classified into special categories depending on the type of welding processes and equipment used during the process. Some welding machines use transformers for converting high voltage, low current electricity into high current low voltage. These types of welding machines are the least expensive and allow welders to select the output current.

Other Machines use an internal combustion engine or an electric motor to drive the alternator or generator present in these machines. The process used is similar to transformer based welding machines.

Portable Spot Welder Design Provides Welding Power Equivalent to Many Welders

Shellmax has been manufacturing resistance welding equipment like portable spot welder has been in thousand operations of manufacturing facilities providing consistent quality spot welding in production. Portable spot welder design provides welding power equivalent to many welders much superior in size and costing many times the price. A timed burst of current far in excess of 1000 amperes passes through the metal, heating it to its melting point. Under regular pressure from the arms, the metal fuses together. Overall, the whole welding process takes a fraction of a second. An optional sheet metal stand with a foot pedal activator is available to free the operator's hands for handling materials. For featuring built-in heavy production usage optional reduces sheet metal water cooled arms and tips are solid state timer fabrication costs recommended.


Tips to use of portable spot welder


Galvanized coating is a relatively poor conductor of electricity; galvanized steel does not weld as readily as uncoated steel.

Welding is a suggestion to minimize burn marks on stainless steel: place a piece of copper about 1" square over the side of the metal where do not want a burn mark to appear. Weld the stainless steel through the copper and any burn will be negligible.

For production welding, accomplish the same thing by grinding the tip which rests on the finished surface as broad as possible. File the other tip to a point and you can perform consistent welds on stainless with negligible burn.

Getting the most from welder it is necessary to input power is as high as possible. Therefore recommended, the welder can be connected directly or close to fuse box as possible. If an extension cord is needed, be sure to use at least cables for the best results.

Welding two pieces, the portable spot welder will weld two pieces of round wire together. The diameters of the wires, you can weld deeply exceed the thickness capacity listed for the machines. For best results, contour slots are filed into the tips so that they act as a holding jig when welding the wire.

Producing devices are many uses for the units. It is excellent for heating small metal parts cherry red for hardening. If the thickness of the piece to be hardened is greater, you may have to re-bend the arms slightly.

TIG Welders Work For Creating Arc Weld

TIG welders work for creating an arc between a metal to be bonded and a tungsten electrode. The arc creates the weld, while gas fed through a torch seals off the welded area and protects it from the atmosphere and other conditions that might affect the weld involves a lot of heat and electric current, so it is very bright and requires the use of a welding shield.


TIG welding uses tungsten electrodes dissolve during the weld. TIG uses a filament that burns away after the weld is complete. Each can use a filler rod or steel. TIG welders classically can use no filler bar at all to bond two pieces of thin metal together, while they use long filler rods for thicker metals. The rods are fed into the weld to fill the gap during torch provides the seal for weld.


TIG welding is very high superiority and measured one of the best welds in industry work. Students need to understand how the gas acts must control the movement of the torch and filler very carefully. TIG welders use argon gas, combination of helium and argon. It used to be performed using helium gas only, when it was invented in the 1940s but argon gas proved to be more efficient and is the most common gas used today.

Some Tips and Tricks To Help Improve Stick Welders Skills

Many welders are not sure for type and size of the electrode used in stick welders. The size of the electrode should match the circumstances of welding within thickness of metals.


If you purchase an A/C only welding equipment, then you require to get stick welders rods specifically created to weld on A/C. That not all stick welding rods are created the same.


For victorious stick welders, you need to use an arc length same distance from the metal as the thickness of electrode. For example, if you own an electrode 1 inch thick, then arc 1 inch thick as well. Don’t stop thinking about that as you exploit the stick electrode, you will need to move it closer to the metal.
