Lorch T300

$0.00 Sale Save

Possibly the most portable 3 phase 300A TIG machine on the market.

In a very small casing, this machine is an excellent TIG welder for onsite use and as a portable workshop machine.

Being German made, this 300 Amp Tig welder is very simple to use, with a 3 step to weld interface theory:
1. Select method
2. Select mode
3. Select welding current

The ControlPro model allows you to save up to 100 preset job procedures which can be recalled.

Available in both DC and AC/DC models, and watercooling unit can be instantly plugged in ready for use.



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.

Optional Equipment
While designed for mobile applications, the Lorch T 300 can be converted into a handy, yet fully capable machine suitable for use in the workshop by upgrading it with an optional water cooling system. When mounted on an optional Maxi Trolley, it fully retains its mobile capabilities even with the water cooling system fitted.

Changeover DC to AC

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