Are you ready for the future?

The welding system you can rely on.

Soaring costs, increasing competitive pressure, ever more complex customer requirements – we understand the challenges you are facing in order to combine investment security and solution competence.

Our solution is using the best technology available in a smart manner. Further digital development that keeps coming, combined with greatest efficiency and performance, makes a decisive difference in Industrial welding production.

We have put all we have into delivering on this value proposition with the iQS. A completely new inverter ensures control stability and the best arc available from within the Lorch portfolio. Our highest priority is giving our customers greatest availability in their production with the iQS. Every part has been tested for tough industrial use and adapted accordingly. This, combined with the intuitive operation, makes the technology accessible to every welder.

Absolute High-end Welding Performance.

Our high-end welding unit series guarantees optimum results through advanced development and experience – for greater efficiency, cost savings and satisfaction.


New Smart Process Control Engine.

Time equals money – it certainly does in production. A new SPC engine allows us to develop welding processes and suitable synergic lines and to transfer them to your iQS even more quickly. We are also happy to incorporate our customers' ideas in this. This makes it easy to create new innovations – in record times. In any case, you will always get cutting-edge equipment – no matter the market developments.

Clean weld seams, barely any spatter.

A newly developed RCS module (Rapid Current Shutdown) has enabled us to further improve our short arc processes. The result is a particularly clean process with less spatter and even higher weld seam quality. This saves your welders the need for elaborate rework and thus plenty of time and money.

Another advantage for the user: The weld pool can be better controlled and manipulated. This improves welding greatly, in particular thin sheets <3mm.

New inverter.

A new, robust inverter was developed for the iQS. It makes processes run even more stably and smoothly. Users can steplessly adjust parameters and select the perfect working point for them. This improves the weld seam quality and minimises rework.

Its high performance also makes the iQS ideally suited for robot connections – offering an opportunity for companies to further optimise operator comfort, cost efficiency, and welding results. Experience welding 4.0.

Optimal welding behaviour saves time.

Faster to get started: The iQS offers the right synergic lines for virtually any application – rendering major corrections unnecessary.

Faster in the process: Our speed synergic lines enable faster welding for the user.

Faster to finish: Our processes are particularly low-spatter, saving elaborate rework.

Precise welding at the highest level of excellence.

Get started with iQS in practice.

Speed meets intelligence.

Increase your weld performance through fast processes, smart networking and intuitive operation.

Strong performance

Get started faster with the right welding programme. Speed up your processes with our Masters of Speed and finish faster with particularly spatter-free welding.

Smart networking

Connect directly to the Lorch Connect Portal via WLAN. Record welding data in real time and view it conveniently in the app or web browser, regardless of location.

Easy to use

Intuitive and highly practical. This means that individual parameter settings can be conveniently made during welding.

Robust construction

User-friendly on the outside and easy to service on the inside. This is how you get functional details and a low-maintenance layout in one system.
