The V-series.Heavy-duty TIG welding for pros.

High-end TIG performance in the industry, on the construction site and for mobile use, perfectly equipped with V-series.

The demands on TIG welding systems are very high in pipeline and tank construction as well as in the automotive or in the aviation industries. Welding in awkward positions is a regular feature here. The V-series is the perfect equipment to weld virtually any material, from alloy steels to copper, at the highest performance.

The diverse V series range includes both mobile systems to be used on construction sites and systems that can be perfectly integrated into an industrial environment. The V-series has just the right solution for any conceivable welding task.

Optimised arc properties combined with a sophisticated industrial housing.

Overview of the advantages of the V-series.

The V-Series is perfect for your TIG welding tasks. It shows best welding performance in spite of high duty cycle and power.

Contact-free HF ignition increases arc stability and optimises material transition. The automatic final phase reduction ensures a perfect weld end due to the clean end-crater filling. Additionally the automatic dbDown function in the AC/DC version makes AC welding much quieter and reduces noise pollution by up to 40%. There is even more though!


Stable arc – at DC and AC.

The V-Series is available as a DC and AC/DC version on any performance output level. The V-Series stands out particularly with its highly stable arc. The arc shape is optimised for excellent cleaning effect of the aluminium oxide layer and for reduced noise alike when welding with AC. The AC/DC version has an automatic cap shaping function as well. Its square-wave current gives the V series additional boost and greatest arc stability when welding aluminium.

The V-series housing is robust and secure.

The high-end technology inside the V-series is protected by a robust industrial metal housing that is ideal for outdoor use. The fully resilient handles allow suspension of the power source from the crane and hold the welding cables. The double gas cylinder safety device maximises safety within the production environment.

Pulsing and fast pulsing at up to 20 kHz.

The integrated pulse and fast pulse function at up to 20 kHz is particularly suitable for welding thin sheets. It also permits outstanding weld pool control for perfect results even with difficult welding tasks.

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.

Optimal parameters with the SmartBase.

SmartBase technology guarantees a perfect arc matching your chosen electrode diameter with welding parameters, ignition, and working range automatically adjusted and optimised. The arc can be fine-tuned individually for best freedom and to warrant welding with the optimum arc.

Mobile-Car and water circulation cooler for better ergonomics.

Mobile-Car permits work with the V-mobile devices at your ideal working height. Rest assured that your gas cylinder will be stowed away safely at all times. As the torch will be cooled correctly at all times thanks to combination with the water circulation cooling unit (Lorch WUK), V-mobile devices no longer differ from classic systems in any respect. Quite to the contrary, they offer even greater mobility.


No compromises: The V-series operation concept.

The digital amp display and the clearly structured user interface with clear welding sequence control turn current adjustment into an intuitive and precise process. The inclined control panel of the V-series always provides an optimal view of the parameters set and ensures perfect ergonomics.

True to the principle of “3 steps to weld”, all you need to do is set the welding method and trigger function and the desired welding current. You can also easily save your parameter settings thanks to the integrated Tiptronic function.



  • “3 steps and weld” operating concept
  • Simple one-button operation
  • Stepless current adjustment
  • Digital Volt-Amperage-display
  • LCD graphic display with language selection
  • 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.

Smart V-series functions for greater efficiency in welding production.

The job tool stores up to 100 welding tasks.

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

Linked production: Plug & Weld with LorchNet.

LorchNet is a modern interface to optimise communication between different Lorch devices. The LorchNet interface makes it easy to connect a cold wire feeder.

Optimising processes: Welding data recording with Lorch Connect.

The data recording conceals enormous potential for decisive improvement of the quality, productivity, and profitability of your processes by knowledge.

As a result, Lorch has developed a cloud solution that is as cost-effective as it is easy to operate, providing the transparency required and helping you digitally master your daily tasks:

This optional add-on records your welding production data to let you analyse your processes and optimise them in a targeted manner.
