Arc Welding Power Source

CLOOS Welding Power Sources — QuesT Series

Reliable and efficient, the new generation of CLOOS high-frequency TIG power sources offers excellent arc ignition and welding performance. Stable deep-pulse operation focuses the arc for deep penetration in thick plate and high welding speeds on thin sheet.

Product Features

QuesT 402/452/552 — High-Frequency TIG Power Sources

Low-current ignition from 3 A, with Deep Pulse and adaptive frequency adjustment for deep penetration and high welding speeds. QuesT 402/452 can be expanded with AC/DC modules.

Typical Applications

Defense applications (magnesium, aluminum and titanium alloys)

Aerospace precision structures

Petrochemical applications, especially pipe-joint welding

Pressure vessels, including 9Ni/5Ni steel tanks and LNG storage tanks

Nuclear power industry

QINEO TIG-HF-I/E — TIG Ignition Module

QINEO TIG-HF-I/E — TIG Ignition Module

Modular ignition units are available for internal or external installation. Standard monitoring components include water-flow, temperature and ignition-voltage monitoring, plus an interface for a single-wire drive system.

Reliable TIG arc ignition even with long cables between the power source and torch.

The ignition module and ignition-voltage-free cable connection to QINEO QuesT simplify complex installations and systems.

Significantly reduces high-frequency ignition interference with other system components, improving availability.

QINEO QN-TWTIG — Robotic Torch Unit

QINEO QN-TWTIG — Robotic Torch Unit

Combines a TIG torch, cold-wire drive and feed system, and collision shutdown device in a high-performance head for automated TIG welding. Torch mounting angles of 0° or 45° provide flexibility for different welding tasks.

Compact design for easy access to complex components.

High repeatability through fine, precise adjustment of the cold-wire feed and tungsten electrode.

High power capacity with a powerful water-cooled torch and excellent electrode cooling.

High-quality precision torch with actual wire-value recording.

QINEO-TT-HW — Manual TIG Torch

QINEO-TT-HW — Manual TIG Torch

Robust, high-quality components ensure reliable processes and excellent welding results. The modular design supports air or water cooling and both low- and high-current welding.

Ergonomic handle for comfortable operation and reduced wrist strain.

High-quality welds in all welding positions.
