You need to know your tools before making the best use of them. If you want to be a welding expert, and care about impeccable work, you need to know all different types of welding machines, and scope of their applications. This article will discuss 3 basic types of welding machines.
3 Basic Types of Welding Machines
Spot Welders
Spot welders are often employed in the production of automobiles as well as in their maintenance, and the fundamental workings of these machines are rather straightforward. They operate in a manner somewhat dissimilar to that of a staple gun:
Copper electrodes are used to compress stacked sheets of metal under pressure.
Copper allows unimpeded passage of electricity, but the steel or aluminum that is being welded presents a barrier to that flow.
The metal gets heated due to the friction caused by the resistance.
When it reaches the melting point, the two or more sheets will combine into one.
The spot welder repeatedly pinches the metal for a brief period of time while it is cooling, creating a solid nugget that holds the parts together.
If you have ever seen the skeleton of an automobile, you have most likely seen the round patches that link the various components. This is called a spot weld. This kind of welder is used to connect the new piece of the frame that is installed whenever a collision tech replaces a section of the frame. See the article on “Shop Basics: Auto Body Spot Welders” for a more in-depth examination of spot welders.
Brazing Welders/MIG Welders
A MIG welder, also known as a Gas Metal Arc Welding (GMAW) welder, may be thought of as the “hot glue gun” of welders since it is used to fuse two pieces of metal that are butted up together to make a junction. This can be done either flat or at an angle. With a MIG welder:
A clamp is used to attach an electrode to the piece of metal being worked on.
A wire is continuously fed through the cannon by the machine and deposited onto the metal.
The wire acts as the second electrode, and when it is brought into contact with the metal, it causes an electrical arc to be created. This arc creates a puddle of molten metal that joins the pieces together.
A gas that acts as a shield is expelled from the gun in the same manner. This gas lives up to its billing by preventing contaminants from penetrating the weld.
Welding using a MIG welder is typically easy to learn and requires just a little bit of experience; nevertheless, there are a few things that make it even simpler to handle:
A lightweight gun: the pace of the wire feed is controlled by the welding machine, while the speed of the gun is controlled by the operator. The procedure will be a lot less difficult for you if you use one that is not cumbersome and is not heavy.
Push/pull torch: When utilizing a thinner wire to weld materials such as aluminum, there is a possibility that the wire can buckle while it is being pushed out by the wire feeder on the machine. This is especially true when employing a push/pull torch. A push/pull torch applies a pulling force in addition to the pushing force, which results in tension in the wire and decreases the likelihood of buckling and welded mesh.
A soft-start feature: This option, which is available on welders like the MULTIMIG 522, feeds the wire more slowly at the beginning of a weld for a smoother start than would be possible without the soft-start function.
Stud Welders
This sort of welder does exactly what it sounds like it does, which is to fuse a stud onto a metal piece. Within the gun, an arc is created when the metal and the stud come into contact with one another. The molten substance is forced onto the metal by the stud welder, and as it cools, a connection is established between the two components.
Dent repair often requires the use of this particular kind of welder. You would first insert a stud into the depression, then pull it out to pop the dent out, and finally, you would cut the stud off.

A repair business will often have all three types of welders available for use. Wiltz, a welding tools and equipment Qatar provider, provides single phase welding machine Qatar along with all the other types.
