DC TIG Welding

Direct Current TIG Welding Mode - Professional Technical Guide

Technical Operation

Direct Current Flow Characteristics

Utilizes direct current flowing in one direction from electrode to workpiece, creating a stable and focused arc with consistent heat distribution throughout the welding process.

Electrode Configuration

Electrode remains negative (DCEN - Direct Current Electrode Negative) for optimal tungsten electrode life and superior arc stability during operation.

DCEN polarity provides exceptional arc control and tungsten longevity for professional welding applications
