THE T-SeriesA very special class of mobile TIG welding performance.

The workhorse for mobile TIG welding tasks.

The T-Series is a workhorse in TIG welding. As a true all-rounder, it is at home anywhere, from the food or chemical industry, to piping, machine, or metal construction, to crafts. Its low weight makes it particularly suitable for mobile use on construction sites as well as for service and repair welds with difficult access situations. 

In spite of its compact housing, it offers a very diverse range of functions. The T-series stands out with optimal welding performance due to its high-end technology, perfect HF ignition, and powerful fast pulsing for the thin-sheets. An integrated cooling unit connection for the WUK cooling unit makes welding even more comfortable and further increases outputs

Maximum flexibility and best welding result.

Overview of the advantages of the T-series.

The T-Series maximises flexibility since it is available in DC and AC/DC versions in all performance output levels. It also comes with a low weight of 12-16 kg that is unparalleled in its performance range. The system also can be operated with a generator and can be customised as required. The T-Series can be retrofitted the WUK torch cooling unit using its water-cooling plug-and-play connection. 


Perfect aluminium welding thanks to AC version.

Aluminium TIG welding requires alternating current (AC). Since aluminium is a very good conductor of heat, 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-series welding units. Beyond this, the AC mode optimises the current form for greatest stability, outstanding cleaning effect of the aluminium oxide layer and reduced noise. The integrated automatic cap shaping function ensures perfect tungsten 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. 

Mobile at the construction site.

The T-Series is compact enough to fit your TIG equipment in the optional protective assembly trolley. Your entire system, including its cables, tools, helmet, and gloves will be safely stowed and can be pulled along with you in its case. 

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 welding thin sheets. It facilitates outstanding weld pool control for perfect results even with difficult welding tasks. 

Energy efficiency at full power.

The Lorch T-series features state-of-the-art power electronics with stand-by function to reduce your costs while achieving perfect welding results


At barely more than 13 kg, the T-series is perfectly equipped for mobile use. The special drop protection keeps the housing safe at falls from a height of up to 60 cm. The standard protective cover of the control panel and the integrated dust filter ensure robustness and durability even in rough working conditions. 

MMA welding.

The T-series is also suitable for MMA welding. The arc-force control comes in when welding, ensuring arc stability and perfect material transition. The electrode will not stick or anneal due to the anti-stick system.

Mobility and full power on construction sites and in the industry.

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

The digital amp display and the clearly structured user interface of the welding unit 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 trigger function and the desired welding current.

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.

Maximum TIG welding comfort with the T-series using the smart features by Lorch.

The job feature stores up to 100 welding tasks.

The Tiptronic job memory function can directly store the optimised parameter settings for up to 100 welding tasks and recall them on demand 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 change 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. 

Greater quality, productivity, and profitability for your welding production.

Made possible by digitalisation. Made simple with Lorch Connect.

Data collection has enormous potential. It provides information on every single parameter along your value chain to decisively influence quality, productivity, and profitability of your processes. As a result, Lorch has developed a cloud solution that is as cost-effective as it is intuitive to use, providing the transparency required and helping you digitally master your daily tasks. 

Lorch Connect records your welding production data to let you analyse your processes and optimise them in a targeted manner. Add the optional Lorch Connect to your T-series welding unit for a digital overview

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