Before outlaying a wad for portable welders consider the intended use first. Welding is process where two or more metalic work pieces are joined together by melting them together with the introduction of heat and upon cooling the metal solidifies and forms the required bond. Modern technology by way of the inverter principle allows portable welders to get the desired outcome in some very tight places.
Welding is a very easy process to learn and almost anyone could perform it with ease after receiving proper guidance and training. Welding as a part time job pays quite well and many immigrants while they are studying tend to work in factories or industries part time. Using a cheap portable welder provides the opportunity for you to learn, master the art without blowing a hole in your budget. After some experience you can either get a bigger machines if you find it interests yo or just walk away having experienced it on a budget.
From an industrial perspective, factories engage in MIG or TIG welding procedures for welding different kinds of metals and alloys. The procedure adopted largely depends upon the characteristics and properties of the metal that is needed to be welded.
MIG welding-Portable Mig Welders
Also known as Gas Metal Arc Welding is a semi-automatic welding procedure in which continuous wire electrode and a shielding gas is fed through a welding gun. The wire electrode that is fed through is also consumable and thus for performing this kind of welding procedure, you need immense amount of raw materials depending upon what is needed to be welded. A constant voltage and current power supply is used for carrying out the task. And you have four different types of methods that can be used for the transfer of metal to form the bond. They are globular, short circuiting, spray and pulsed spray. Each of these methods has their own distinct properties, advantages and limitations.
TIG welding-Portable Tig Welders
Also known as Gas Tungsten Arc Welding is an arc welding process that uses non-consumable tungsten electrode to produce the weld. It also makes use of a shielding gas for protecting the surroundings from contamination along with a filler metal. A constant source of power supply acts as the power supply unit for carrying out the task. This power is conducted across the arc through plasma.
Stick Welding-Portable Stick Welders
Also known as Shielded Metal Arc Welding is an arc welding process that uses consumable electrode coated with flux to produce the weld. During the process as the weld is laid, the flux coating disintegrates giving off vapors that serve as a shielding gas.
Portable Welders-Portable Welding Equipment
Portable welding machines are also known as carry around welders. They enable via the use of minimising electronics found inside inverter welding machines, access to areas that are considered difficult to get to. These light weight welders are used by many fabricators that operate mobile welding businesses.
