Distinguished by their high efficiency and superb welding characteristics, inverters utilise digital software control
technology that has a significant influence on the outcome of the welding process.
SmartBase is the name of the expert database devised by Lorch to control the arc. This database lets you adjust the
parameter settings yourself, giving you the freedom you need to tweak and correct even the finest details of the process
you are applying.
The standard pulse function with up to 2 kHz that is built into every machine offers you additional benefits when welding
Using the TipTronic facility, you save your ideal setting for each weld so that you can effortlessly retrieve the settings one
at a time using the Up-Down or Powermaster torch when performing recurring welding tasks.
Electrode welding with Hotstart, Anti-Stick and Arc-Force regulation: The automatic Hotstart feature guarantees perfect
ignition every time, while the Anti-Stick system reliably prevents the electrode from sticking, and Arc-Force regulation
supports the welding process when you are dealing with difficult electrodes.
Welders often experience that the conditions on site do not allow them to place their welding machine right beside them.
When faced with this type of situation, they find the use of a remote control helpful as it allows them to intervene and
adjust the welding current if necessary. This is why Lorch has included a large variety of different hand and foot remote
controls in their T series, which are ready for use right away thanks to their plug&play support.
Featuring a water cooling system that is housed in a compact mobile case, the Lorch TF-Pro 300 is perfectly suited for use
at workshops on site.
Available as DC and AC/DC versions in all power variants, Lorch's T series provides you with maximum flexibility.
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.
Lorch's interval-spot function reduces distortion during thin sheet metal welding.
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.
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).
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.
