DC Pulse TIG Welding

Advanced Pulse TIG Welding Mode - Professional Technical Guide

Technical Operation

Current Cycle Characteristics

DC Pulse TIG welding alternates between high (peak) and low (base) current in precisely controlled cycles, creating a rhythmic welding pattern that optimizes heat input and control.

Dual-Phase Process

The peak current phase delivers focused penetration and fusion power, while the base current phase maintains arc stability while allowing critical cooling periods for the weld pool.
