Lorch TF Pro AC/DC Wire Feed


Is this the best 300A workshop TIG Welding Machine for Australia?

This workshop TIG welder is a true showcase of German engineering. Lorch has developed a 300 Amp welding power source with an in-built cold wire feeding system. The user can either use a standard TIG torch or the automatic cold wire feed torch. The TF-Pro 300 auto wire feeding TIG simply takes a standard spool of MIG wire and has a similar feed system to the MIG. Up to 99 user programmed settings can be stored in the machine and recalled with a press of a button on the TIG torch.

The auto cold wire feeder can be programmed easily and in many different ways:
- Program it to feed continuously or only feed wire in on high pulse
- Change wire feed speed on both high pulse and low pulse
- Set a pre welding delay for wire feed
- Manually adjust wire feed from the TIG torch
- Etc!

This setup is possibly the best TIG welder for Aluminium welding as the auto wire feeder can feed wire in so consistently and quickly. Aluminium TIG welding can be difficult as the user has to feed wire in so quickly on a standard machine, whereas lesser skilled users can now perform superior quality welds thanks to the feed system!

Thanks to the pulse characteristics of the machine, this has enabled us to weld Schedule 40 pipes in a single pass with no edge preparation, in an automation application. The setup offers excellent bang for the buck, get in touch for a demonstration!


Outstanding TIG welding characteristics thanks to inverter technology
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.

The SmartBase expert database provides for optimum arc conditions
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.

Pulse and fast pulse up to 2 kHz
The standard pulse function with up to 2 kHz that is built into every machine offers you additional benefits when welding thin plates.

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 function
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.

Remote control
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.

Mobile with integrated water cooling
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.

Changeover DC to AC
Available as DC and AC/DC versions in all power variants, Lorch's T series provides you with maximum flexibility.
