TIG DC welding power source up to 550 ampere for manual welding

QINEO QuesT 552 Master for manual TIG DC welding

Start your next TIG mission with QINEO QuesT: The new high-tech welding power source solves highly demanding manual TIG welding tasks reliably and efficiently. The QINEO QuesT is characterized by precise ignition properties and optimal process functions. The stable and focussed arc which is easy to control over the entire power range guarantees excellent welding results. When TIG pulsing, you benefit from the high dynamics of the QINEO QuesT which enables fast current transitions even with large capacity differences - so you get perfect welds. The Deep Pulse function stabilises and focuses the arc so that the arc pressure is increased. This can result in both deep penetration for thick sheets and high speeds for thin sheets. A multitude of components, functions, interfaces and configuration possibilities make the QINEO QuesT to be your individual power source for manual welding - exactly how you need it for your welding tasks.

  • Excellent ignition properties even under difficult conditions
  • Deep pulse function produces a stabilised and focused arc for deep penetration or high welding speeds (Deep Pulse up to 20 kHz)
  • Excellent control behaviour enables a stable arc over the entire setting range
  • Optimum process functions for best welding results
  • Fast transitions even with large capacity differences (TIG pulses)
  • Modular design and extensive accessories for individual adjustment of the QINEO QuesT to your needs
  • Comfortable operating concept for easy, quick and intuitive handling
  • High-quality components and a robust design in proven CLOOS quality
