WHAT YOU NEED TO KNOW ABOUT THE WIRE WELDING MACHINES

The wire welding machine is an equipment originally developed for the purpose of welding different types of metals using inert gas, hence the initials used to identify it: MIG Metal Inert Gas.

Here, we will look at the general working principle, applications and parts of a wire welding machine.

Let’s get started!

The wire welding process consists of preserving a solid wire electrode arc and the workpiece.

The wire welding process consists of maintaining an electric arc between the solid wire electrode and the piece to be welded, which is fed by a welding gun, which contributes to reducing material losses and increasing productivity.

Currently there are three main techniques used for gas metal arc welding: short circuit transfer, spray arc transfer and globular transfer. The short circuit transfer process is also known as thick transfer, short arc and as wire, and it is characterized in that the change of the metal to make the union occurs by an electrical short circuit at the tip of the wire.

On the other hand, drip transfer is the technique in which small metal droplets are obtained from the wire tip and projected into the molten or liquefied solder. Finally, in globular transfer, droplets of molten or liquefied metal are used that have a considerable size, which allows them to join by force of gravity.

These welding techniques can be used with different materials, such as stainless metals, carbon steels and aluminum, among others, thanks to the fact that it offers great efficiency due to the capacity of the continuous electrode, which does not have to be constantly changed unlike other options. Therefore, welds can be carried out continuously, without the need to pause between one bead and another. There are other benefits, such as the lightness of the welding instruments, which facilitates their transport and handling, their ease of operation and the great versatility with the materials and alloys that can be used.

As with any arc welder, it is essential to know the parts that make up a wire welding machine and adopt the necessary safety measures for its proper use. The elements found in a welding machine of this class are the flow meter, the welding torch or gun, the pressure regulator, the shielding gas cylinder, the gas supply hose, the wire or electrode, the power source, an ammeter, a voltmeter, a power cable, a return cable, a work clamp, and a consumable wire feeder.

It is necessary to take into account that wire welding shares the characteristics with MAG and they are generally described together, one being an arc welding with shielding gas and the other being an arc welding with inert / active gas.
