lastwelders – The three efficient welders

The three best welders that have been ruling the welding industry are arc welder, plasma cutter and tig welder. Even though different types of welding machine exist, these three machines are called as the best welding machines. Why it is called so? It is called so because it has all the features and qualities that best suits the welding industries. Arc welding has been called as one of the oldest type of welding process and tig welding comes under the category of mid type welding process and plasma cutter have now joined in the list of modern welding machines. So in this article, let us see why these three welding machines are called as the best welding machines in brief. Let us first start with the oldest type of welding process called as arc welding and the arc welding process.

Arc welder is a device that joins the more pieces of steel or metals together and it has the capability to generate enough heat so that it can melt the pieces of metal or steel in a quick way. Arc welding is in practice from 1802, but the welding machines that were invented in those days were not portable and it was very heavy to carry and leave outside more polluted gases. Whereas now the arc welders that is in existence has excellent features and weld the metals in an easy way. It is available in different types in market in affordable prices. Power arc 160 and power arc 200 are the two welding machines that are available in market now. Both these types are of Infineon igbt inverter type and it is typically used in different applications and also has good hot start.

The next welder that we are going to discuss is plasma cutter. It is called as the scientific and modern welding features and preferred more by different industries due to its excellent features and reliability. It accurately cuts the metal with ease and it uses high voltage electrical arc and plasma gas so that it welds the metal quickly and easily. In market you can find different types of plasma cutter welding machines such as super cut40, 50, 50p, power plasma 50, 60, 70, 60E, 80 and 100. Each type has over current warning facility and cuts the metal of different thickness. It is widely used in different industries and also cuts as faster than any other welding machines. It has good duty cycle and also accuracy is its advantage.

Tig welder is a non consumable welding process and it has been developed in a fast way with good features. In market, the following tig welders are available and they are power I-tig 200, powertig 185 micro, powertig 200DX, powertig225LX, powertig 250 EX and powertig 315DX. As like other machines, it also has best features. So when you buy these three welding machines, buy with care so that you can buy the best one and efficient one.

How to build a metal welding table part one   by Goscor ARC

Goscor ARC – Johannesburg South Africa
A steel welding table is a basic necessity for any welder’s workspace, since welding on a wooden surface can present a very real fire hazard. In addition, with a steel table, the welder’s work clamp can be attached to it, and parts placed on the table will be electrically connected with the table’s surface. This provides the advantage of keeping the work clamp and its cable out of your way while welding. Finally, building your own welding table will allow you to stand upright and place smaller projects at the right height for welding.
Following are instructions for building your own metal welding table. All of the items, with the exception of the metal plates needed for the shelves, can be found readily available at your local home improvement store. The steel plates can be purchased from a local steel supplier easily found in your local yellow pages. Expect to complete this project in less than four hours.
safety first
1. Ventilation
It is important to use enough ventilation to keep the fumes and gases from your breathing zone. For occasional welding in a large room with good cross-ventilation, natural ventilation may be adequate if you keep your head out of the welding fumes. However, be aware that strong drafts directed at the welding arc may blow away the shielding gas and affect the quality of your weld. In planning your workshop ventilation, it is preferable to use ventilation that pulls fume from the work area rather than blows necessary shielding gas away.
2. Electric Shock
Remember, electric shock can kill. Wear dry, hole-free leather gloves when you weld. Never touch the electrode or work with bare hands when the welder is on. Be sure you are properly insulated from live electrical parts, such as the electrode and the welding table when the work clamp is attached. Be sure you and your work area stay dry; never weld when you/your clothing is wet. Be sure your welding equipment is turned off when not in use. Note that Lincoln wire feed / welders have a relatively low open circuit voltage and include an internal contactor that keeps the welding electrode electrically ‘cold’ until the gun trigger is pressed. These important safety features reduces your risk of electric shock during any welding project.
3. Arc Rays
It is essential that your eyes are protected from the welding arc. Infrared radiation has been known to cause retinal burning. Even brief unprotected exposure can cause eye burn known as welder’s flash. Normally, welder’s flash is temporary, but it can cause extreme discomfort. Prolonged exposure can lead to permanent injury.
4. Workspace – Protection from Sparks
Before you get started on any welding project, it is important that you make sure your work area is free of trash, sawdust, paint, aerosol cans and any other flammable materials. A minimum five-foot radius around the arc, free of flammable liquids or other materials, is recommended. Extra care should be taken in workshops that are primarily used for woodworking as sawdust can collect inside machines and in other hard to clean spaces. If a spark finds its way into one of these sawdust crannies, the results could be disastrous. If your shop area is too small to allow for a safe radius, please use an alternate area like a garage or driveway.
5. Gas Cylinders
Cylinders can explode if damaged. Always keep your shielding gas cylinder upright and secured. Never allow the welding electrode to touch the cylinder.
6. Safety Equipment
It is also imperative to make sure you have all the necessary safety equipment and that you’re wearing welding friendly clothes. You should wear:
7. Welding gloves – dry and in good condition
Safety glasses with side shields
Protective welding shield with a dark lens shade appropriate for the type of welding you do
Head protection – like a fire retardant cotton or leather cap
Long-sleeve cotton shirt
Long cotton pants
Leather work boots
A fire extinguisher should also be on hand during any welding.
Also, make certain no children are in the area when you are welding. They may watch the arc and can experience retinal damage from its intense light. There is also a risk of a child getting burned by welding spatter.
