Unique: Integrated cold wire feeder.
The fully integrated wire feeder with a separate, removable control panel and highly accurate cold wire control reliably feeds the filler material into the weld pool to achieve the greatest TIG productivity.
A 4-roll quality feed motor ensures reliable, precise wire feeding. Digital speed monitoring ensures a perfect weld seam. As the welding current is increased, the automatic setting will automatically adjust the feed rate to match.
The downward sloping wire to roller position exit ensures easy wire change over as well as reliable wire feeding, even with aluminium wires.
Perfect aluminium welding thanks to AC version.
Aluminium TIG welding requires alternating current (AC). Since aluminium is a very good heat conductor, a higher current is required for every additional millimetre of material thickness. The TF-Pro 300 also welds aluminium with material thicknesses in excess of 8 mm easily. Beyond this, the AC mode optimises the current waveform for greatest stability, outstanding cleaning effect of the aluminium oxide skin and reduced noise. The integrated automatic cap shaping function ensures perfect tungsten ball shape as well.
Improved welding quality thanks to MACS.
The additional special Lorch MACS (ModulatedACSystem) process improves welding quality by way of targeted heat application. MACS provides outstanding results, in particular when joining different material thicknesses.
Pulsing and fast pulsing at up to 2 kHz.
The integrated pulse and fast pulse function at up to 2 kHz is particularly suitable for processing thin welding sheets. It enables outstanding weld pool control for perfect results even at difficult welding tasks.
Interval spot function.
The interval spot function reduces heat application. This is of special benefit for welding tasks where disortion and dark temper colours must be avoided, e.g. when processing thin sheets.
Energy efficiency at full power.
The integrated stand-by function ensures turns individual components on and off automatically. The Thermocontrol sensors monitor system temperature and adjust the fan as required to reduce fan noise, dust load inside the machine, and power consumption.
The TF-Pro housing is extremely robust and mobile thanks to its sturdy handles. This makes it ideal for use in a workshop. The top of the housing also makes for a perfect storage surface.
