5 things you should know before purchasing a welding machine

A welding machine is used in joining metals, repair, fabrication, and industrial maintenance. As there are various kinds of welding machines, you should know how to choose the best machine as per your needs.
The following guidelines will help you in narrowing down the available options:
Type of welding process
• Arc welding – It is also called as stick welding. An arc will be produced on the metal to be welded by the stick (electrode) through the passage of electricity. Even though stick welding is a complicated process, it is cost-effective and results in a strong bond. It is the most popular method of welding process as it can be used both indoors and outdoors. After completing the job, the spatter should be removed, and the welding area should be cleaned. The job is ideal for thick metals.
• MIG welding – The wire feed welding is very easy. Clean welding can be produced both on thick and non-thick metals. The welding machine will let you work with various metals, including steel, copper, aluminum, and nickel alloys.
• TIG welding – It is a welding process in which an electrode and inert gas will be used. Usually, thin sections are welded by implementing TIG welding. A strong weld can be produced, and it is a time-consuming job.
• Flux core welding – flux-cored wire will be used to shield the arc. This type of welding can be accomplished in rough and harsh terrains. You can work with rusty and dirty materials. The deep penetration with the weld will help in producing stiff joints.
Type of metal
The type of metal that you are working on will influence the purchase of the welding machine. If you are working with steel or stainless steel, you can go for MIG, TIG, and stick welding.
Aluminum alloys can be worked with either MIG or TIG welding machine.
While working with cast iron, you will want to go for a stick welding machine.
Copper, brass, magnesium, and other exotic metals can be joined by using a TIG machine.
Working conditions
For outdoor working conditions, MIG welding is not the right choice. The wind may blow the shielding gas, and you may end up with porous joints. Stick welding delivers stable results in the outdoor environment. Compressed gas availability such as oxygen, carbon dioxide, and argon should be verified before placing an order for the welding machine. Homeowners can implement MIG welding, and it can be learned very quickly. The sparks that generate during the welding process should not fall on combustible items. Hence, the selection of the surroundings should be made carefully.
Power source
The power source is an essential factor while shopping for a welding machine. If you are working with a 110v outlet, the choice will be limited. However, a wide variety of devices are available which run on 110 volts AC.
The welding machine cost is based on current consumption. If you are working with thicker metals, more current is required. It would help if you also considered the thickness of welding fixtures.
Accessories
• There are many accessories available in the market to use with a welding machine. However, you should buy essential items and other items as per the nature of the welding job.
• To protect your eyes, you should wear a welding mask or helmet. It gives protection from harmful UV rays, and the inflammation of eyes can be prevented.
• Hand protection is a must during the welding process. Hence, it would help if you bought either generic or specialized glove as per the nature of the welding job.
You can shop online for industrial welding machines, tools, consumables, and accessories. By following the general guidelines provided by the manufacturers and safety at the workplace, you can undertake a wide range of welding jobs.
