What is AC/DC Pulse TIG Welding Machines?

AC/DC Pulse TIG Welding Machines are advanced welding devices that offer both alternating current (AC) and direct current (DC) modes along with a pulsing feature. These machines are designed for Tungsten Inert Gas (TIG) welding and provide versatile capabilities for welding different types of metals with high precision.


AC and DC Modes: Capable of operating in both alternating current (AC) and direct current (DC) modes, making them suitable for a wide range of metals.

Pulse Function: Includes a pulsing feature where the current alternates between a high (peak) current and a low (base) current at a controlled frequency.

Precision Control: Allows detailed adjustment of welding parameters, including pulse frequency, peak current, base current, and pulse duration.

Inert Gas Shielding: Uses an inert gas, typically argon, to shield the weld area from atmospheric contamination.

Non-Consumable Tungsten Electrode: Employs a tungsten electrode that does not melt during the welding process, providing a stable arc.


Versatility: Capable of welding a wide variety of metals, including aluminum (with AC) and steel (with DC).

Improved Weld Quality: Enhances weld penetration and fusion while minimizing defects such as porosity and cracking.

Enhanced Control: Provides better control over the weld pool and arc stability, making it easier to weld difficult materials and complex geometries.

Oxide Cleaning: In AC mode, the alternating current helps clean the oxide layer on aluminum surfaces, resulting in better weld quality.
