Can You Pulse Weld With Standard Mig Welder
If you are a professional welder or just an enthusiast, you might have heard about pulse welding. But what exactly is pulse welding, and can you achieve it with a standard MIG welder? Let’s explore this interesting topic and find out if pulse welding is possible with the equipment you already have.
First, let’s understand what pulse welding is. Pulse welding is a technique that allows you to control the amount of heat input into the weld puddle by pulsing the welding current. This pulsing action creates a series of high and low current cycles, which in turn helps to control the weld pool size and reduce heat input. The result is a more precise and controlled weld that reduces the risk of distortion and improves the overall quality of the weld.
Now, can you achieve pulse welding with a standard MIG welder? The answer is yes, but with a caveat. While some MIG welders come with pulse settings as a standard feature, many standard MIG welders don’t have this capability. However, it is possible to add a pulse function to your standard MIG welder by using a pulse welding upgrade kit or a separate pulse welding unit.
With a pulse welding upgrade kit, you can retrofit your standard MIG welder to enable pulse welding. These kits typically include a pulse control module that connects to your welder’s existing power source and a control panel that allows you to adjust the pulse parameters. By installing this kit, you can transform your standard MIG welder into a pulse welding machine.
Alternatively, you can also invest in a separate pulse welding unit that can be used in conjunction with your standard MIG welder. This unit connects between your MIG welder and the power source and provides the pulse control function. While this option requires additional investment, it allows you to keep your standard MIG welder unchanged and use the pulse welding unit only when needed.
In conclusion, while a standard MIG welder might not have pulse welding capabilities by default, you can achieve pulse welding by adding a pulse welding upgrade kit or using a separate pulse welding unit. With these additions, you can enjoy the benefits of pulse welding, such as improved weld quality and reduced distortion, without the need for a specialized welding machine.
Understanding Pulse Welding
Pulse welding is a variation of the conventional MIG welding process that involves the use of pulsing current to weld metals. This technique is commonly used when welding materials that require precise control and reduced heat input, such as thin metals.
The pulsing current in pulse welding allows for better control over the weld pool and helps to minimize distortion and heat-affected zones. By pulsing the current, the welder can alternate between a higher peak current for good fusion and a lower background current to allow the metal to cool slightly between pulses.
When the peak current is applied, the weld pool is formed, and as the background current is applied, the weld solidifies. This pulsing action creates a series of overlapping weld spots, resulting in a stronger and more consistent weld.
Pulse welding offers several advantages over conventional MIG welding, including:
- Reduced heat input: With pulse welding, the heat input is reduced, minimizing the risk of warping and distortion in the base metal.
- Better control: The pulsing current allows for precise control over the weld pool, resulting in improved weld quality.
- Increased welding speed: Pulse welding can help increase welding speed, as the pulsing action allows for faster solidification and less cooling time.
- Enhanced weld appearance: The overlapping weld spots created by pulse welding result in a more aesthetically pleasing and consistent weld appearance.
It’s important to note that pulse welding requires a welding machine capable of producing pulsing current. While certain MIG welders may have pulse welding capabilities, not all standard MIG welders are capable of pulse welding.
In conclusion, pulse welding is a specialized welding technique that offers several benefits over conventional MIG welding. With its ability to reduce heat input, provide better control, increase welding speed, and improve weld appearance, pulse welding is a valuable option for welding applications that require precise control and reduced heat input.
Pulse Welding with Standard MIG Welders: Pros and Cons
-
Pulse welding is a technique that can be used with standard MIG welders to achieve improved welding results.
-
Pros of pulse welding with standard MIG welders:
-
Increased control: Pulse welding allows for better control over heat input, resulting in reduced distortion and better weld quality. This is especially beneficial when welding thin materials or working on delicate projects.
-
Improved aesthetics: Pulse welding can produce more aesthetically pleasing welds, with smoother bead appearance and minimal spatter. This can be particularly advantageous when working on projects that require a high level of precision and visual appeal.
-
Better gap bridging: The pulsing action of the welder helps to bridge gaps between joints more effectively, reducing the need for extensive pre-weld preparation and resulting in stronger welds.
-
Increased weld penetration: Pulse welding can improve weld penetration by focusing the heat input on the workpiece more effectively. This can be beneficial when working with thicker materials or when welding in challenging positions.
-
Reduced heat input: Pulse welding allows for a lower average heat input compared to continuous welding, which can be advantageous when welding heat-sensitive materials or when aiming to minimize distortion.

-
Cons of pulse welding with standard MIG welders:
-
Equipment limitations: Pulse welding requires a MIG welder with pulse capabilities, which may not be available on all standard models. Upgrading the welder or using a specialized pulse welding machine may be necessary.
-
Additional complexity: Pulse welding can be more complex to set up and requires a good understanding of welding parameters such as pulse frequency, pulse width, and peak current. It may take some time and practice to achieve optimal pulse welding results.
-
Increased cost: Upgrading to a MIG welder with pulse capabilities or purchasing a specialized pulse welding machine can add to the overall cost of welding equipment.

Questions and answers
Can I pulse weld with a standard MIG welder?
Yes, it is possible to pulse weld with a standard MIG welder by using a pulse welding function or by using a spool gun attachment.
What is pulse welding?
Pulse welding is a welding technique that involves rapidly pulsing the welding current on and off to create a more controlled heat input. This can result in improved control over the weld pool and reduced distortion.
Can I pulse weld without a pulse welding function on my MIG welder?
Sadly, you cannot pulse weld without a pulse welding function on your MIG welder. This function is necessary to control the pulsing of the welding current.
What is a spool gun attachment and how can it help with pulse welding?
A spool gun attachment is an accessory that can be added to a standard MIG welder. It allows you to use a separate wire feed system and control the wire speed independently, which can be beneficial for pulse welding.
