THE T-Pro-Series.TIG high performance for the workshop.

Optimal, safe, and flexible welding performance in your workshop.

The T-Pro series with its robust yet compact housing is the perfect TIG power source for your workshop. It can be relocated quickly and flexibly for its next assignment. At the same time, the gas cylinder for up to 50 l will always stay safely connected to the power source. 

No matter if you are working in the food or chemical industry, in pipeline, machine, or metal construction: the water-cooled T-Pro series feels at home in the industry as well as in crafts. It stands out with optimal welding performance due to its high-end technology, perfect HF ignition, and powerful fast pulsing in the thin-sheet area. 

Best TIG welding properties due to inverter technology.

Overview of the advantages of the T-Pro series.

Software currently decisively influences welding results. The T-Pro series with digital control technology stands out with its high efficiency and particularly good welding properties. SmartBase technology warrants a perfect arc at all times, matching your chosen electrode with welding parameters, ignition, and working range automatically adjusted and optimised. 


Perfect aluminium welding thanks to AC version.

Aluminium TIG welding requires alternating current (AC). Since aluminium is a very good heat conductor, a higher current is required for every additional millimetre of material thickness. Material thicknesses far exceeding 8 mm can be handled easily by the T-Pro series welding units. Beyond this, the AC mode optimises the current form for greatest stability, outstanding cleaning effect of the aluminium oxide skin and reduced noise. The integrated spherical cap automatic function ensures perfect arc shaping as well. 

Improved welding quality thanks to MACS.

The additional special Lorch MACS (ModulatedACSystem) process improves welding quality by way of targeted heat application. MACS provides outstanding results, in particular when joining different material thicknesses. 

Pulsing and fast pulsing at up to 2 kHz.

The integrated pulse and fast pulse function at up to 2 kHz is particularly suitable for processing thin welding sheets. It permits outstanding weld pool control for perfect results even at difficult welding tasks. 

Interval point function.

The interval point function reduces heat application. This is of special benefit for welding tasks where warp and temper colours must be avoided, e.g. when processing thin sheets. 

Energy efficiency at full power.

The integrated stand-by function ensures turns individual components on and off automatically. The Thermocontrol sensors monitor system temperature and adjust the fan as required to reduce fan noise, dust load inside the machine, and power consumption

Robust housing.

The T-Pro housing is extremely robust and mobile thanks to its sturdy handles. This makes it ideal for use in a workshop. The top of the housing also makes for a perfect storage surface. 


The T-Pro series by Lorch in use

Overview of the intuitive and precise operation concepts of the T-Pro series.

The amperometric digital display and the clearly structured user interface with clear welding sequence control turn current adjustment into an intuitive and precise process. True to the principle of “3 steps to weld”, all you need to do is set the welding method or cycle function and the desired welding current. 



  • “3 steps and weld” operating concept
  • Simple one-button operation
  • Stepless current adjustment
  • Amperometric digital display
  • User-focused operator guidance with illuminated symbols and welding sequence control
  • Tiptronic job memory for 100 welding tasks

3 steps and welding:

Best operation. Best welding result.

Lorch systems are so easy to operate because we integrated many of the things you have had to adjust since as assistance systems during development. A maximum of 3 steps and you weld perfection. The rest runs in the background. A very good system serves you, not you it. Operate - without you having to deal with it.

“Welding thin sheets in the 1.5-millimetre-range is a sophisticated art. The T-Pro has enabled us to meet the high welding requirements in all respects. The units have proven themselves to be exceedingly robust, handy, and entirely trouble-free even in continuous operation.”

Werner Huprich

Managing director at Michelfelder Edelstahltechnik GmbH

"Controllers and buttons are quick and easy to adjust, even while wearing welding gloves. The simple operation concept generally is a big plus bonus of the T-Pro. The transition in our company went perfectly smoothly."

TIG welding comfort at its best with the smart Lorch features of the T-Pro series.

The job tool stores up to 100 welding tasks.

The Tiptronic job memory function can directly store the optimal parameter settings per welding task and recall them at need right from the power source. This provides clear added value when welding workpieces with different weld seams, while making recurring welding tasks easy and saving time

Just keep welding: Memory function.

Save the time needed to set the welding parameters again even if you have to briefly interrupt your welding work. The T-series’ memory function automatically stores all relevant parameter settings to let you resume your work at any time without any problems. 

Always well-advised with close, personal, and honest support.
