Comparison of mechanical welding machine and electronic welding machine? What kind of machine should I buy?

Mechanical welding machines are known to be the most commonly used equipment in the welding industry, with durability. However, the number of mechanical welding machine manufacturers has decreased significantly due to the rise of electronic welding machines. Users are increasingly prioritizing electronic welding machines for many reasons, including convenience and efficiency. So, should we choose to use a mechanical welding machine or an electronic welding machine? Let’s learn and comparison of mechanical welding machine and electronic welding machine with RX Tradex to get more useful information, thereby making the most suitable decision for your needs.

1. What is a mechanical welding machine?

Mechanical welding machine, also known as welding transformer or arc welding machine, is a device that uses a high-strength AC transformer to melt the metal when welding.

The outstanding advantages of mechanical welding machines are ease of use, durable operation, and good weldability of a wide range of materials.

However, the size of the mechanical welding machine is quite large and the weight is heavy, so moving or installing the machine will cause many difficulties

2.1 Mechanical welding machine

How is an electronic welding machine different from a mechanical welding machine? Although it is no longer popular, mechanical welding machines still have many outstanding advantages, making it a worthy choice for many people in the welding industry. Here are the strengths of the mechanical welding machine:

Advantage:

• Cost-effective: The biggest advantage of mechanical welding machines is that they are significantly cheaper than electronic welding machines, which saves initial costs
• High Durability: Known for its outstanding durability, few failures, and few minor errors, helping users minimize the time and cost of repairs and maintenance later
• Variety of Designs and Capabilities: The mechanical welding machine series has a variety of models and working capacities, suitable for use from civil mechanical welding workshops to industrial welding workshops. Mechanical welding machines are widely applied in iron engineering, construction and many other fields.
• Easy to repair: When a mechanical welding machine fails, repairs are usually simpler and less expensive than an electronic welding machine.

Shortcoming:

• Large weight size: Mechanical welding machines are often large and heavy, making them difficult to move and operate, especially when working in tall or tight positions. However, many manufacturers have now designed more wheels to support easier movement for users.
• High power consumption: Mechanical welding machines consume significant amounts of power, resulting in higher operating costs than modern welding machines such as electronic welding machines.
• Limited weldability: The machine mainly welds iron and stainless steel, cannot weld many metals and special alloys such as non-ferrous metals, alloy steels such as Ni, Al, Cu…
• Outdated technology: To compare mechanical welding machines and electronic welding machines , mechanical welding machines also use old technology, which does not have modern features like electronic welding machines

2.2 Electronic Welding Machine

Advantage

• Compact and convenient size: The electronic welding machine has a compact design, light weight, and is designed with an additional handle, which is convenient to move and install
• Energy saving: Thanks to advanced Inverter technology, it saves up to 30% of energy compared to mechanical welding machines. In addition, electronic components such as transformer cores, copper conductors, etc. are also made from high-quality materials, helping to minimize power waste
• Less failure: Compared with mechanical welding machines, electronic welding machines have fewer problems, and the structure and working principle are not as complicated as mechanical welding machines
• Accurate Display: The  electronic welding machine is equipped with a display screen that displays the current strength (welding current) and working potential, which makes it easy to adjust the welding parameters accurately and easily
• Variety of models: Electronic welding machines come in a variety of models, from 220V welding machines to industrial welding machines; from rod welding machines, Tig welding machines, Mig welding machines to multi-function welding machines.

Shortcoming

• High cost: Compared with mechanical welding machines, the cost of electronic welding machines is significantly higher
• Difficult to repair: Although there are few failures, when an electronic welding machine has a problem related to electronic components, repairing an electronic welding machine is more complicated and expensive than a mechanical welding machine

3. Should I buy a mechanical or electronic welding machine?

Electronic welding machines are becoming increasingly popular in the industry and construction thanks to their many outstanding advantages over traditional mechanical welding machines. With a compact, easy-to-use, energy-efficient design while still providing the best welding quality, electronic welding machines also meet all welding needs in different fields.

In particular, with a variety of welding functions, working capacity, brand and price (ranging from 1 million to 80 million VND) depending on the working capacity and demand, there will be different prices

Although electronic welding machines are popular due to their outstanding advantages, traditional mechanical welding machines still have a significant number of users. Because this is a familiar equipment of many long-time welders. Outstanding with high durability and large load capacity, meeting the ability to work continuously without worrying about affecting the durability of the machine.

The choice between mechanical and electronic welding machines depends on your specific needs, working environment, and budget. If you need a durable, uncomplicated and reasonably priced equipment, a mechanical welding machine will be the right choice. On the contrary, if a modern, flexible, and energy-efficient equipment is needed, an electronic welding machine will be a worthy investment.
