Strong MMA-250 250 amp inverter welding machine
Inverter or welding machine model MMA-250 is offered with STRONG brand. This product is used to connect metal parts. Wrong inverter 250 amp inverter welding machines, unlike traditional welding machines, have lighter weight, stronger and more uniform welding power, as well as saving energy consumption and also a more reasonable price. In addition, the MMA-250 strong inverter welding inverter has The actual output is 250 amps with the ability to weld the electrode from size 1.6 to size 5 mm.
In this machine, MOSFET technology is used, which is one of the advantages of welding machines with MOSFET technology, such as lower repair costs and more efficiency of this technology in the climatic conditions of all cities of our country.
This device is derived from PWM technology with constant current and output control to perform strong and uniform welding. One of the most prominent features of this device is significant savings in electricity consumption and also the device’s resistance to power fluctuations up to 15%.
This machine has a quality switch to turn the machine on / off, as well as two (volume) keys to adjust the output current and the welding depth. With the digital display on the device, you can easily see the amount of amp output. And adjusted the output amp value according to the type of workpiece.
The device has a green LED light to indicate the power connection and a red LED that lights up when there is a problem in the device so that the user is fully aware of the general condition of the device.
Working cycle of MMA-250 welding machine
The working cycle of this machine is 60% and its welding type is electric arc.
This device works only with 220V single phase electricity (even with 15% oscillation).
Also, inside the package of this device, quality accessories are used so that the buyer does not seek to buy various accessories after purchasing this device.
The accessories of this device include quality welding pliers with 5 meters of 100% copper cable.
All parts of this device, such as diodes, clamps, capacitors and transformers, are used from the highest quality global brands. This device has a quality handle for easy movement and also has the IP21 safety standard for high safety of the device as well as user safety.
Dimensions of MMA-250 welding machine
Considering the dimensions and weight of this type of welding machine, it is not a problem to carry and move it. It is produced in the dimensions of 48X30X18 cm and weighs about 11.5 kg.
There are two volumes for adjusting the output current of the device on its panel.
With the help of these volumes, you can adjust the output current of the device between 25 and 250 amps.
If you are familiar with the principles of electric welding, working with this Strong inverter device will not be a problem.
You can connect electrodes with a diameter of 1.6 to 5 mm to the pliers of this device.
This Strong product has IP21S resistance standard.
Advantages of MMA-250 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).
Reasonable price due to the use of electrical components instead of raw materials such as wire, 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 current, which switches on and off quickly, 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. Therefore, 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 MMA-250 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.
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
