How does continuous MIG welding differ from pulsed welding in terms of control?

Continuous MIG welding maintains a constant current throughout the welding process, which allows the welder to create a stable and consistent arc. This steady application of current is beneficial for achieving uniform bead profiles and penetration depth, leading to reliable weld quality. The constant current also simplifies the welding process for operators, as they do not have to make frequent adjustments during the weld.

In contrast, pulsed welding features varying current levels, which allows for better heat management. This technique can help to minimize heat input and control distortion, especially on thin materials, but it requires a different approach to welding. Continuous MIG welding does not typically involve the same level of complexity in current variation, thus leading to a more straightforward operational experience.

While considerations like fewer adjustments or manual intervention may be relevant in understanding the nuances between different welding methods, the key defining characteristic for continuous MIG welding is its emphasis on a constant current, ensuring predictable and controlled welding conditions.
