GYS EXATIG – HF TIG Welding Module for EXAGON Generators
The GYS EXATIG is a high-frequency (HF) TIG ignition and control module designed for use with DC current generators such as the GYS EXAGON 400 CC/CV. It provides complete TIG process management including HF or Lift start, gas synchronization, torch control, and pre/post-gas adjustment. Compact, lightweight, and portable, the EXATIG integrates directly with compatible power sources without requiring an auxiliary power cable. Operators can control rise/fall times, pulse frequency, and current directly from the torch using the potentiometer function. Optimised for professional workshops and mobile operations, the EXATIG’s rugged construction, integrated gas flowmeter (5–25 L/min), and precise cycle control make it an ideal solution for fabricators demanding flexibility, precision, and ease of use in TIG and MMA applications.
Who Is It For + Pros & Cons
Perfect for bodyshop technicians, industrial fabricators, and site welders seeking to add high-quality TIG welding capability to their DC generator setups.
- Pros: Compact and lightweight, generator compatible, HF or Lift start, gas and torch synchronization.
- Cons: Requires DC power source, limited to DC TIG (no AC for aluminium).

Frequently Asked Questions
1. What power sources are compatible with the EXATIG?
The EXATIG is designed for use with GYS EXAGON 400 CC/CV and most DC welding generators capable of delivering 14–100 V output.
2. Can it weld aluminium?
No. The EXATIG operates in DC TIG mode only and is not suitable for AC aluminium welding.
3. Does the EXATIG require a separate power cable?
No. It connects directly to the welding power source and operates without an auxiliary supply.
4. What functions can I control with the EXATIG?
You can adjust pre-gas, post-gas, rise time, welding current, pulse frequency, and fall time, with remote control possible via potentiometer torch.
