Understanding Pulsed MIG Welders

What is Pulsed MIG Welding?

Pulsed MIG welding is a welding process that utilizes a pulsing current to create intermittent droplet transfers between the electrode and the workpiece. Unlike traditional MIG welding, where a constant current is used, pulsed MIG welding alternates between high peak currents and low background currents. This controlled pulsing enables precise heat input and greater control over the weld pool.

Advantages of Pulsed MIG Welding

Pulsed MIG welding offers several advantages over conventional welding methods. Firstly, it reduces heat input, minimizing distortion and the risk of burn-through. The controlled heat input also enables welding thinner materials without compromising their integrity. Additionally, pulsed MIG welding provides better control over the weld pool, resulting in improved weld quality, reduced spatter, and increased productivity.

Exploring Double Pulse MIG Welders

How Does Double Pulse MIG Welding Work?

Double pulse MIG welding is an advanced variant of pulsed MIG welding that introduces a second pulsing current during the welding process. This additional pulsing further enhances control and precision, especially when welding challenging materials. The first pulse creates a weld pool, while the second pulse adds energy to refine the weld and improve its mechanical properties.

Benefits of Double Pulse MIG Welding

Double pulse MIG welding offers unique advantages, making it suitable for various applications. The additional pulse allows for better control over heat input, resulting in improved weld bead appearance and reduced distortion. It also facilitates welding thin-gauge materials with ease. Moreover, the double pulse technique enhances the weld’s mechanical properties, providing increased strength and durability.
