Navigating Short Circuit and Globular Transfer Modes in MIG Welding

Metal Inert Gas (MIG) welding, also known as Gas Metal Arc Welding (GMAW), utilizes various transfer modes to adapt to different welding needs. Two notable modes are Short Circuit and Globular transfer. Each has unique characteristics that make them suitable for specific applications. This blog post delves into these two transfer modes, exploring their nuances, advantages, and best use cases to help welders optimize their MIG welding techniques.

Understanding Short Circuit Transfer Mode

Short Circuit Transfer is characterized by the welding wire making contact with the workpiece, creating a short circuit. This happens several times per second, as the wire feed stops and starts, producing a crackling sound. It’s predominantly used for thinner materials and provides excellent control over the welding process.

Key Characteristics:

  • Low Heat Input: Ideal for thin materials to prevent burn-through.
  • High Accessibility: Suitable for all positions and especially useful in confined spaces.
  • Controlled Metal Deposition: Minimizes spatter and allows for precise welding.


  • Automotive repair, where thin sheet metals are common.
  • Domestic and industrial applications requiring fine detail and minimal distortion.

Exploring Globular Transfer Mode

Globular Transfer, unlike Short Circuit, involves the transfer of molten metal in large droplets across the arc. This mode operates above the threshold set for Short Circuit but below the levels necessary for Spray Transfer.

Key Characteristics:

  • Higher Heat Input: Suitable for thicker materials but can lead to increased spatter.
  • Cost-Effectiveness: Uses less shielding gas compared to other methods like Spray Transfer.
  • Limited Positioning: Best used in flat or horizontal welding positions due to the size and behavior of the droplets.


  • Heavy fabrication works where thickness and filler volume are more significant than finish.
  • Construction projects requiring robust welds on larger components.

Comparing Short Circuit and Globular Transfer

While both transfer modes are useful in their rights, they serve very different purposes:

  • Material Thickness: Short Circuit is preferable for thin materials to avoid warping and damage, whereas Globular is better for thicker materials where heat input and deeper penetration are needed.
  • Control and Precision: Short Circuit provides more control and precision, making it ideal for intricate or delicate welding tasks. Globular, due to its nature, is less precise and can be messier.
  • Speed and Efficiency: Globular transfer can be faster in depositing material on thick workpieces but at the cost of finish quality. Short Circuit is slower but offers a cleaner finish.

Best Practices for Each Mode

Short Circuit:

  • Maintain a lower voltage to avoid too much heat.
  • Use a consistent and controlled feed speed to prevent excessive spatter.
  • Regularly clean and maintain equipment to ensure optimal performance.


  • Opt for a slightly higher voltage setting than Short Circuit to maintain the globular droplet formation.
  • Be mindful of the work environment as wind can affect the stability of the arc.
  • Prepare for post-weld cleanup due to potential spatter.


Both Short Circuit and Globular transfer modes have distinct places in the MIG welding arsenal. Understanding when and how to use each can greatly enhance a welder’s efficiency and the overall quality of their work. Whether you’re working on a delicate piece of art or a heavy-duty industrial project, mastering these techniques will ensure that you can tackle any welding challenge that comes your way.
