Inverter welding machine (inverter welding or inverter welding transformer):
These machines have many advantages, so over the past ten years they have quickly replaced all welding machines.
Advantages of MMA160S welding machine
Very low weight, small size, low power consumption, no power fluctuations, high quality welding,
Can be used with all types of conventional alloy electrodes, non-adhesion electrode and output (D.C) (MMA160S welding machine).
Reasonable price due to the use of electrical components instead of raw materials such as copper winding and… has made this welding machine popular.
Inverters are the new generation of welding machines. Some of these devices work with both alternating and direct current
Others work only with direct current DC.
These machines are used in most welding activities due to their lightness and quality welding.
Comparison of welding machines
An old welding machine uses a large iron core transformer to convert high-voltage low-current AC power into high-voltage AC low-voltage current.
It is then converted to DC using an AC rectifier, but the inverter welding machine first converts the input to DC with the help of an AC rectifier.
This fast-on and off current produces a direct high-frequency current of about 10,000 to 20,000 Hz.
This high frequency and low current is the power supply for the transformer where the current increases.
The main difference between the performance of inverter welding machines and older welding machines in general is how the input AC to DC output current is converted.
Due to the new technology used in the structure of inverter welding machines, their production cost is much lower than previous machines.
It saves on the cost of production of the machine. In addition, inverter welding machines have stronger welding power compared to previous welding machines.
Other advantages of MMA160S welding machine
In this process, the quality of welding is increased and energy consumption is saved.
In addition, welding with inverters does not contain any noise pollution.
Energy savings, sufficient welding, portability, stable arc, high unload voltage and proper arc power balance are the advantages of inverter welding machines.
Usable electrode material
Acid and alkali electrodes, stainless steel electrodes and iron design electrodes are used in welding with these devices.
Note: Due to the use of electronic circuits instead of iron cores in these devices, it is necessary to observe the following two things:
When buying a suitable device, be careful in terms of production quality and the presence of its parts and spare parts.
Second, when using, pay special attention to the working capacity written as% on the device.
The work cycle inserted on the top of the devices shows the continuous activity of the device.
For example, a 40% work cycle means that every 10 minutes 6 minutes of work and 4 minutes of the machine is on but welding is not done with it.
Applications and differences
Rectifiers are used for welding steel structures and heavier work.
Lightweight inverters are used in more detailed cases and welding of lighter works, especially in the installation sector.
Most importantly, it works with single-phase electricity and can be used for limited home use.
Another difference is the weight of the welding machine; A 200 amp rectifier welding machine weighs about 25 kg.
But a 200 amp inverter welding machine weighs about 8 kg.
On the other hand, the amount of amperage received by the inverter welding machine from the grid during welding is between 18 and 22 amps.
The rectifier sometimes exceeds 25 amps, which causes the house power to fluctuate and the fuse to actuate.
Dimensions and strength of MMA160S welding machine
The size of the welding machine changes with increasing amperage. for example;
A device weighs 160 amps 4 kg, 200 amps 8 kg, 250 amps 11 kg and finally 500 amps weighs about 55 kg.
Of course, welding machines below 100 amps are also available, which have special and more limited applications with low weight.
Welding machine efficiency from 160 amps to ballast.
It is suitable for light work and welding of indoor installations or installation of billboards and 160 or 200 amp devices.
Those who want to do welding work professionally and on a large scale.
Like making metal structures, tanks and heavier jobs, they use a three-phase welding machine over 250 amps.
Due to the excessive variety of rectifier, inverter and inverter welding machines in the market, buyers are very confused.
Therefore, observing some considerations will be effective in choosing the right product.
Welding inverters work with different technologies, including:
- Inverter welding with MOSFET technology
Inverter welding with IGBT technology
Inverter power supply has the ability to provide high current for welding.
The inverter welding machine uses a series of rectifiers and solid state switches to convert 60 Hz AC (AC) of input power to DC (DC) output.
The amount of output current and voltage can be adjusted and can be controlled by computer software during the welding process.
