Gasless MIG welders have some notable differences compared to gas-shielded MIG welders:

1. 1. No shielding gas required: Gasless MIG welders use flux-cored wire, which eliminates the need for shielding gases like CO₂ or Argon. The flux inside the wire contains components that generate gas during welding, protecting the weld from oxygen and impurities in the air.
      
   2. Cost-effective and easy to use: The absence of a shielding gas cylinder reduces costs and simplifies the welding preparation process. This makes gasless MIG welders easier to use, especially for home or DIY applications, where users may not need to manage gas cylinders or adjust gas pressure.
   3. Suitable for outdoor environments: Since shielding gas is not required, gasless MIG welders perform more effectively in outdoor or windy conditions, where shielding gas might be blown away, compromising weld quality.
   4. Portable and suitable for small spaces: Without the need for bulky gas cylinders, gasless MIG welders are typically lightweight and easier to move, making them ideal for small workspaces or mobile applications.
