SCR MIG 500

A thyristor MIG welding machine is a type of welding machine that uses thyristors to control the current and voltage during the welding process. This type of machine is known for its high efficiency and precise control, which makes it suitable for use in a variety of welding applications, including automotive, aerospace, and construction. Additionally, thyristor MIG welding machines are often used in automated welding systems, such as robots and other automated machinery.

SCR MIG 500

Mig 500 Welding Machine Features:

1. Current, voltage and speed unified adjusting and separated adjustable, easy for less skilled users and for experienced users.

2. With energy saving function, machine could automatically turn off if machine stops for 2 minutes.

3. Auto-lock crater function reduces the labor intensity and makes welding control more convenient.

4. Present function makes it easy to control the initial welding and seam shape.

5. Melting ball control, ready for the next arc striking.

6. Over-load protection avoids machine damaged by accident.

7. Mainly used in welding low carbon steel, low alloy steel and other ferrous metals; also can weld stainless steel, aluminum and aluminum alloy with mixed gas or inert gas shielding.

8. Strong ability of anti-fluctuation of power supply, the ratio reaches 15% ( industrial requirement 10%).


There are several advantages of using a thyristor MIG welding machine over other types of welding machines:


High efficiency: Thyristor MIG welding machines are known for their high efficiency, which means they can produce a high-quality weld with less heat input, reducing distortion and warping.

Precise control: The thyristor control circuit provides precise control over the welding current and voltage, which allows for consistent and high-quality welds.

Consistency: Thyristor MIG welding machines are often used in automated welding systems, which allows for consistent and repeatable welds, making them ideal for mass production.

Low maintenance: Thyristor MIG welding machines are generally low maintenance, which means less downtime for repairs and maintenance.

Wide range of materials: They can be used on a wide range of metals, including aluminum, stainless steel, and mild steel.

Versatility: Thyristor MIG welding machines can be used for both manual and automated welding, making them a versatile option for a variety of welding applications.
