What Factors To Consider When Selecting a Pulse Mig Welder?

Pulse MIG welding can offer numerous benefits to your workshop or fabrication business, including increased productivity. However, due to its complexity and higher cost compared to conventional MIG, it is crucial to select a machine that will provide optimal results and a good return on investment in the long run. Here are some key factors to consider:

• Single-Pulse or Double-Pulse welding machine? When selecting a Pulse MIG welder, it’s important to consider whether you want a Single-Pulse or Double-Pulse machine. Double-pulse mode takes the advantages of single pulse, such as improved weld quality and finish, to a higher level. Not all pulse MIGs come with double-pulse mode, and single pulse can be seen as an “entry-level” option for those learning or testing pulse MIG. Single pulse machines typically have fewer features and adjustments. However, many operators now prefer double pulse. It’s essential to check the machine specifications to ensure you know what you’re getting.

• Track Record: When it comes to developing a functional and dependable Pulse MIG, many welder manufacturers have attempted and failed. It’s a fact that nothing beats experience, especially in the case of pulse welding. Therefore, our top recommendation is to select a proven machine from a well-established manufacturer with a track record of success.

• Simple vs Complex: Compared to conventional MIG, pulse welding is less forgiving, and even minor issues like a loose connection or incorrect setting can lead to frustrating results. While it’s tempting to opt for a machine with numerous features and options, it’s important to remember that this also increases the potential for errors. The most dependable and user-friendly pulse machines usually have a simpler design that primarily focuses on pulse MIG function.

• Controls: Unfortunately, it’s not uncommon to come across operators who were attracted to the advantages of pulse welding but found their machine challenging, perplexing, and time-consuming to learn and operate. Conversely, intuitive and easy-to-follow controls will optimize your welding time, minimize downtime, and simplify the training of new operators.

• Single Phase? As mentioned earlier in this article, creating a single-phase Pulse MIG that performs well is a difficult task. Therefore, it’s crucial to choose a reputable and experienced manufacturer and be cautious of single-phase pulse machines that are overloaded with functions unrelated to pulse MIG.

• Wire feed system: In pulse welding, consistent and reliable wire feeding is crucial. Drive systems from specialist manufacturers are often used by welding machine manufacturers, so it’s essential to investigate the origin and track record of the drive system. While a robust build is important, other less apparent factors are also critical, such as whether the system is purely mechanical or electronically synchronized with other machine components.

• Push-Pull Ready? Once you become proficient in pulse welding, you’ll likely want to do more of it. A push-pull torch, typically 8m long, is an excellent way to increase the reach and portability of your machine, particularly when welding aluminum, where using conventional torches longer than 3m can be problematic. In the case of push-pull torches, both the torch ‘pull’ motor and the machine ‘push’ motor must be synchronized, which necessitates compatibility between the torch and the machine. Therefore, it’s crucial to not only choose a machine that is “push-pull ready,” but also ensure that a push-pull torch is available specifically for the machine you’re considering and that the torch is a tried-and-tested quality design from an experienced manufacturer to ensure reliability and value from your investment.
