The Jasic Tig 400 Pulse Inverter is a three phase power source, which comes complete with a trolley and water cooling unit.  With a DC pulse function, this machine is feature rich at a very attractive price point.  Coupled with the industry leading Jasic 5 year warranty, this Tig unit is built to last.  A duty cycle of  400 Amps @ 50% (40ºC) and excellent reliability is achievable thanks to the signature IGBT technology used in Jasic inverters.

This TIG Welder utilises HF arc ignition for a non-contaminated start in Tig welding mode and incorporates a gas solenoid for automatic regulation of gas.  Also featuring Down Slope, Post Flow and Auto compensation for voltage fluctuation.  The machine also benefits from 2T and 4T functionality so the user is offered more dexterity and decreased fatigue during welding producing cleaner and more accurate results.  In 2T, press the button to begin the weld and release to stop.  In 4T, press the button on the torch to start the weld, release, then press the button again to stop.

The TIG 400p is suitable for welding various ferrous metals including stainless and mild steel with excellent results, thanks to the welding parameter storage and pulse function.  The unit can also be used as a MMA power source for Arc Welding.  In Arc Welding, the “Hot Start” function also assists in beginning the weld with difficult to start electrodes.

As with all Jasics, this machine comes with a market leading 5 year warranty.  This is backed up by their certified ISO 9001 quality management system and a product range that fully complies with CE, RoHS, C-TICK, CSA and CCC standards.
