How to choose to buy the right electronic welding machine

In recent years, welding and cutting technology in Vietnam has made significant strides with the introduction of many new types of electronic welding machines, each with different capacities and features to cater to diverse working needs. To choose a suitable electronic welding machine,  The welder needs to understand his needs and the working conditions available. The article below RX Tradex will provide detailed instructions on how to choose to buy an electronic welding machine correctly and efficiently.

1. How to choose to buy an electronic welding machine based on your needs

1.1. Capacity

When choosing to buy an electronic welding machine, it is important to choose the right capacity for your needs. If you are an individual who uses a welding machine infrequently and does not need high power, then a welding machine with a capacity of 3.6 to 4.9KVA will be a reasonable choice

On the contrary, if you are a professional welder with the need to use a welding machine regularly and continuously, it is recommended to choose a welding machine with a capacity greater than 4.9KVA to meet the work requirements.

1.2. Welding current strength

Welding current strength is an important factor that determines stability during the welding process. Typically, mini electric welding machines have a welding current strength in the range of 160-250A with a 1-phase voltage of 220V, while larger electronic welding machines have a welding current strength of 250-500V with a 3-phase voltage of 380V.

The electric welding machine with welding current strength from 300-350A and 60% load cycle can be used for welding rods with diameters from 1.6 to 6.3 mm. However, depending on the specific requirements of the job, you can choose a more suitable type of welding machine.

1.3. Diameter of welding rod

To choose the right welding rod diameter, you should rely on the welding current strength. Here are some specific guidelines:

• – For 1mm welding rod: welding current strength from 20-60A.
• – For 1.6mm welding rod: welding current strength from 60-84A.
• – For 2mm welding rods: welding current strength from 60-100A.
• – For 2.5mm welding rod: welding current strength from 80-120A.
• – For 3.2mm welding rod: welding current strength from 100-150A.
• – For 4mm welding rods: welding current strength from 140-180A.
• – For 5mm welding rod: welding current strength from 180-220A.

1.4. Technology

Besides the basic welding functions, an electronic welding machine, needs to be equipped with many advanced and modern technologies to optimize performance and save energy. Among them, inverter technology is considered the most effective in saving electricity, helping to reduce energy consumption by up to 50-60% compared to traditional. Therefore, the way to choose to buy an electronic welding machine is to pay attention to check whether the product has integrated inverter technology or not.

In addition, other functions are also very important such as the automatic power cut-off function when overloaded or the anti-shock mode. Many welding machines also come with retirement accessories to better support the user.

1.5. Types of electronic welding machines

On the market today, there are 3 popular types of electronic welding machines: TIG, MIG and MAG welding machines. Each type of welding machine has its own advantages and limitations, suitable for different use needs

TIG Electronic Welding Machine: This type of welding machine is designed to weld metals such as aluminum, steel, magnesium, stainless steel alloys, and cast iron. In which, the arc is created between the workpiece and the non-destructive tungsten electrode

MIG Electronic Welding Machine: Also known as wire welding machine or CO2 welding machine, this welding machine uses arc welding in an environment with a protective gas. MIG machines are commonly used to weld hard metals such as alloy steel, aluminum, nickel, and copper

MAG Electronic Welding Machine: Known as a semi-automatic welding machine, this method uses a molten electrode in the presence of CO2 gas. MAG welding machines are often used to weld low-carbon steel structures.

1.6. Warranty

Currently, the average warranty period of electronic welding machines usually lasts from 7 to 18 months. A long-term warranty is always a big plus, because during use, it is inevitable to encounter damage problems. Therefore, choosing to buy an electronic welding machine with a long-term warranty will bring more peace of mind and assurance to users

1.7. Price

The cost of electronic welding machine products on the market today is very diverse, from models priced at 1-2 million VND to high-end products with a selling price of up to 50-60 million VND.

However, through observation and research, we found that electronic welding machines with a selling price of 1.5-5 million VND are very popular and popular with many consumers. In particular, Hong Ky’s electronic welding machines are very popular in this segment.

Products in this price range often have a sturdy design, modern design, and are equipped with many advanced technologies. The most important thing is that the price is quite affordable, in line with the budget of many consumers.

1.8. Which brand of electronic welding machine should I buy?

On the market today, there are many famous and reputable brands of electronic welding machines, bringing many rich options to consumers. Some notable brands include Hongji, Legi, Jasic, RedBo, Fumak, Oshima, Bosch, and Weldcom.

2. Epilogue

How to choose to buy an electronic welding machine requires careful consideration of capacity, welding current strength, integrated technology, price as well as warranty. Clearly determine the needs of use to choose a machine with the right capacity and features. Hopefully, with the information provided by RX Tradex, it will help you find a satisfactory electronic welding machine.
