Setting the New Standard in TIG welding today

The INVERTIG.PRO TIG Range - weld from 3 to 450 Amps - 100% Duty Cycle - only 29.5 kg !  

INVERTIG.PRO TIG Range includes the following features:

  • 3 to 450 Amps

  • 100% Duty Cycle

  • 240A / 280A / 350A and 450A Machines

  • Our lightest 240A DC machine weighs only 24.5 kg !

  • Our heaviest 450A  AC/DC Machine weighs only 29.5 kg !

  • The INVERTIG.PRO range offers the user exceptional arc characteristics and control.-

  • All machines will weld at an incredible 3 amps - This coupled with separate control of the Ignition Energy and start current, allow arc striking on the very edge of the thinest of materials

  • Intelligent Ignition Control - Ignition energy is infinitely variable between 10% and 99% of the welding current for perfectly smooth arc ignition on both HF and Lift-Arc, offering exceptional control when welding thin materials at low amperage

  • Selectable HF Ignition Control - Allows you to tackle the smallest of jobs, even in sensitive electronic and computer environments, offering HF Ignition (which is switched off once the arc is established in both AC and DC modes), Lift-Arc Ignition which establishes the arc without using any HF, allowing for example, the repair of sensitive CNC equipment in hospitals which would normally risk being damaged by high-voltage.

  • Intelligent Start Current Control - The start current is infinitely variable between 10% and 99% of the welding current for perfectly smooth arc starting on both HF and Lift-Arc, offering exceptional control when welding thin materials at low amperage. Often used with Intelligent Ignition Control.

  • Pulse Control as standard - Reduced heat input and increased weld quality and control. Especially useful when welding thin materials. Both conventional and high frequency pulsing is available.

  • Conventional Pulsing - offers pulse times greater than 0.1 second

  • High Frequency Pulsing - between 10 Hz and 500 Hz.-

  • Ultra High Frequency Pulsing - between 500 Hz and 3000 Hz.-

  • Fully Programmable - The operator can store up to 99 programs, offering total repeatability and job selection at a touch of a button-

  • Dual Wave Mode - For the welding of Aluminium. This new patented process allows far greater control of the weld pool when welding Aluminium out of position and results in significant quality improvements. (AC/DC Machine Only)-

  • AC Wave Balance Control - Wave balance can be adjusted from -80% to +80% allowing the arc to be influenced to enhance greater cleaning or penetration during the welding of Aluminium. (AC/DC Machine Only)-

  • REHM Automatic Frequency Control System - The frequency is automatically adjusted to the current intensity during AC welding. This offers superior arc characteristics along with improved tungsten life and efficiency. For difficult applications, manual adjustment is also available.

INVERTIG.PRO - Secure and Simple Operation

Child's play - The REHM operating concept

R-Pilot - wide range of functions and easy to operate

  • Pure ergonomics: Anyone can start using the INVERTIG.PRO immediately.

  • All of the essential settings can be made precisely, and in mere seconds, using a single button.

  • Greatest operating convenience - even with your welding gloves on!

  • The large and clear operating panel is self-explanatory.

  • The centrally arranged R-Pilot can be used to quickly and safely access all sectors of the welding parameters important to the user.

Program Memory

  • The INVERTIG.PRO allows you to save up to 99 programs.

  • This saves time and also enables you to work quickly whilst guaranteeing repeatable welding results at the same time.

Quick Choice Buttons

  • Safety, convenience and time-saving.  The QUICK CHOICE buttons P1 and P2 allow two current settings of a welding task to be saved quickly and easily.

  • These welding programs can be called up by pressing the relevant button, or pressing the R-TIG Up/Down button on the welding torch.
