Price of co2 welding machine

In the process of electric arc welding with shielding gas (GMAW) several types of gas or gas compounds are used. CO2 and argon are the most widely used. The use of CO2 gas as the only shielding gas creates a relatively deep and wide welding line, which is mostly used in submerged arc electric arc welding (FCAW). Pure argon arc welding produces a concentrated arc that results in a narrow weld line with a high penetration depth. The combination of CO2 and argon gas is used to modify weaknesses and complement each other's characteristics and capabilities.

In the GMAW welding process, an electric arc is made between the consumable electrode and the workpiece and is simultaneously isolated by a shielding gas.

The salient features of GMAW process include its high speed, welding of various metals such as aluminum, carbon steels, stainless steel, etc., welding of two heterogeneous parts and welding of ultra-thick parts, which is the most widely used welding process in The industry has become.

MIG welding machines, like TIG welding machines, can be produced and supplied as inverters or rectifiers.


In the following, we will review the prices of several models of CO2 welding machines in the global market:

Advantages of using MiG or co2 welding machine:

  1. Welding with Mig welding machine is fast. The reason for this speed is that welding with a MiG device uses an electrode that is constantly fed and can be used continuously until the device heats up. This welding method is used to connect different metals with different thicknesses. A good weld and the ability to change the penetration of the weld by changing the amount of flow makes it very easy to achieve strong and smooth welds.

  2. MIG welding with capability in all situations, performs horizontal, vertical or flat welding with confidence.


The advantages of wet inverter devices compared to rectifiers include the following:

  1. Rectifiers are rectifiers that convert AC current to DC. Stable arcs and easy arc collisions are far better than AC currents, but the problem is that they create 50 cycles per second. Unlike rectifiers, inverter welding machines convert DC current to AC, and its current cycle increases to about 20,000 cycles per second, which stabilizes the arc better and stronger than the rectifier type.

  2. Although inverter welding technology is more expensive than rectifier welding, professional welders never sacrifice quality for price.

  3. Welding efficiency and quality of rectifier welding machines is about 40-50%, while in the inverter type, they are up to about 90% efficient.

  4. Rectifier welding machines are better used for welding soft steels, while inverter welding machines can weld almost any metal.

  5. Less volume, low weight, lower power consumption, no power fluctuations, very high welding quality, the ability to use common types of electrodes and alloys, no electrode adhesion, wide range and high operating range are other advantages of inverter welding machines.

  6. Disadvantages of inverters are the need for specialized repairs, inefficiency of their semi-automatic type in temperatures below zero degrees Celsius, dust sensitivity and relatively high repair costs.

The GMAW process is widely used in the sheet and automotive industries because it can be used in place of the resistance boiling point process. Also, due to its high welding speed, it is a very suitable option for equipping robots.

In this process, shielding gases react with the gases in the open air and reduce their effectiveness. Also, this process is not a good option for underwater welding, instead, other options can be used, such as the TIG welding process. Another disadvantage of GMAW welding is the presence of holes and porosity in the weld because during welding, oxides on the surfaces of parts and fillers (welding wire) are released and the oxygen in it causes porosity and holes in the welding surface. For this reason, the surfaces of the workpiece and the welding wire must be free of any oxide before starting the welding operation.
