Excellent TIG welding properties using inverter technology

The inverters convince with their high performance and their particularly good welding properties, as the digital regulation technique of the software has a decisive influence on the welding result. The database for experts

SmartBase provides the optimal arc

SmartBase is Lorch’s expert database for arc control. You can change the parameter settings yourself, so you can freely enjoy precision correction.

Pulsing and Fastpuls up to 2 kHz

The built-in pulse function as standard up to 2 kHz gives you additional benefits when processing thin weld sheets.

TipTronic

With TipTronic you will save the perfect settings for each bead, so you can easily refer to them one after the other with the Up-Down or Powermaster torch for repetitive welding tasks.

Electrode welding function Electrode

welding with Hotstart, Anti-Stick and Arc-Force regulation: The automatic hotstart facilitates a perfect ignition, the anti-stick system reliably prevents electrode sticking and the Arc-Force regulation supports the welding process on difficult electrodes.

torch distance

Often times, working conditions do not allow welding equipment to be located directly next to the welder. However, to be able to intervene in the welding process and to be able to adapt the welding current, the remote control is a very useful option. For this reason, the Lorch T-series offers various foot and manual remote controls, which thanks to the “plug & play” function can be used immediately.

Mobile with integrated water cooling

The Lorch TF-Pro 300 integrates water cooling into a compact mobile housing making it perfect for mobile use in the workshop.

DC to AC switching

The T series is available in all power versions as DC and AC / DC versions offering maximum flexibility.

Intelligent Torch Control

Thanks to Intelligent Torch Control (ITC), Lorch’s smart torch control system, the machines included in the T series are capable of detecting whether the inserted torch is a standard torch or one of Lorch’s latest-generation torches. This system offers an extensive range of protective features and affords the welder a significant amount of added convenience.

Interval-spot function

Lorch’s interval-spot function reduces distortion during thin sheet metal welding.

Low energy consumption

The included on-demand function automatically turns the components of your Lorch TF-Pro 300 on and off as needed, while the thermal control sensors monitor the temperature of your system and regulate the speed of the fan accordingly. This smart technology reduces fan noise and dust levels in the machine compartment and helps conserve energy.

Non-contacting HF ignition

The TIG arc is ignited without direct contact by high-voltage pulses. Ignition is triggered with the press of a button to ensure that the tungsten electrode does not come into contact with the workpiece. Putting an end to welds with tungsten inclusions, this technology reduces the strain on the electrode. When working in HF-sensitive environments or on tools, the operator has the additional option of switching to ContacTIG (contact ignition).

Integrated wire feed for TIG cold wire

The wire feeder integrated into the TF-Pro 300 reliably feeds the filler metal to the weld pool. A 4-roll feed motor with a specially tuned gearbox combination is in charge of guiding the wire along. The digital speed monitor ensures precise synchronisation, which is essential for the perfect weld. If the current intensity changes, the automatic setting control will adjust the wire feed speed. The wire outlet, which is pointing down diagonally, combined with the Fast Connect System (FCS) of Lorch’s TIG cold wire torch ensures that the wires are threaded in easily and unwind in a reliable manner even when made of aluminium. The TIG cold wire feed is controlled using a separate, removable control panel.
