Jasic TIG 300P DC Inverter Water Cooled Package

£2,335.00 {price excluding tax}

  • Current Range: 5 – 300A
  • Three Phase
  • Weight: 19.4 Kg


The Jasic TIG 300 DC Pulse inverter is equipped with industrial grade components and microprocessor control for high accuracy and performance.

This technologically advanced inverter with a digital control panel allows for feature rich options and provides 8 channel automatic storage of the welding parameters.

The unit is designed for use in the harshest environments.

This modular design TIG welding system can be assembled with an optional trolley and water cooler where required.


The Jasic TIG 300 Pulse DC is a 3 phase inverter power source, featuring a digital display, suitable for TIG welding of steel, stainless, titanium etc.   This particular package comes complete with a trolley and the modular water cooler, fitting perfectly underneath the power source. A water cooled 12.FT TIG torch and a single stage 2 gauge Argon regulator complete the package.  The trolley is great for workshop use, with all parts neatly stored on a wheeled unit, with space on the rear for an Argon cylinder.

The ideal machine for medium to large production work. The TIG 300P incorporates an innovative and user friendly control panel which offers a digital weld cycle, 6 welding modes and a program memory feature for storing 8 different welding parameters.

The Jasic TIG 300 Pulse 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 supplied Titanium TIG torches can be adapted to incorporate an amperage control on the handle (please ask), or the machine can be used using a foot control for amperage adjustments during the weld.

MMA Functionality

The Jasic TIG 300P DC is the perfect choice for professional TIG welders seeking precise and reliable performance whilst capable of acting as an MMA power source for Arc Welding, benefiting from the following features:

Hot start ignition – easier arc starting in MMA mode with difficult to start electrodes and auto-compensation for voltage fluctuations.

Anti-Sticking function – reduces the welding current if a short circuit occurs during a weld

Self-adaptive arc force technology – maintains the optimum arc conditions during welding, even when using long cables.

Being part of the ‘Jasic Pro’ range, this machine features IGBT Inverter technology meaning the Welder may be run by a generator.

Machine Details

As with all Jasics, this machine comes with a market leading 5 year warranty, far surpassing even the leading brands warranties. Couple this warranty, with feature packed machines and excellent build quality, make Jasic a very difficult product to beat in our opinion. Even after the warranty period, Wilkinson Star (Jasic UK) can repair machines at component level, another very beneficial after sales service. In the event of a breakdown in warranty, Wilkinson Star will arrange collection and return at their cost. All of this is backed up by the certified ISO 9001 quality management system in place in the factories and a product range that fully complies with CE, RoHS, C-TICK, CSA and CCC standards.
