Top Performing Pulsed MIG Welders: Our Bestselling Models
Basic Principles of Pulsed MIG Welding
Pulsed MIG Welding is a precision-based welding process that uses a pulsing current to melt and fuse metal workpieces together. Unlike traditional MIG welding, which continuously feeds filler wire into the welding arc, Pulsed MIG Welding alternates between a higher peak current and a lower background current.
This cycling between currents achieves several benefits:
- Reduces heat input, thus minimizing warping and distortion of the workpiece
- Provides better control of the weld pool, enabling welding in all positions
- Enhances weld quality especially on thinner materials and alloys
Industrial Applications of Pulsed MIG Welding
Pulsed MIG welding has emerged as a useful tool in various industries:
- Automotive: For joining thin metals in car manufacturing.
- Aerospace: Ideal for welding aluminum, a common material in aircraft design.
- Manufacturing: For creating high-quality welds on a variety of metals.
- Marine: Used in the fabrication and repair of ships due to its versatility.
Key Benefits of Pulsed MIG Welding
When compared to traditional MIG welding, Pulsed MIG Welding offers several key benefits:
- Less Spatter: Reduces cleanup and improves overall finish.
- Less Heat: Minimizes warping and distortion, especially on thin materials.
- Better Control: Facilitates welding in all positions and on a wider range of materials.
- Increased Efficiency: Faster travel speeds can be achieved, increasing productivity.
Understanding the Pulsing Process
The process operates by alternating between two distinct levels of current:
- Peak Current: This higher level of current is where the actual welding takes place. It’s sufficient to melt the filler wire and create a weld pool.
- Background Current: This lower level of current maintains the arc, but it’s not high enough to melt the filler wire.
