The Jasic MIG 450 Separate from the Pro range is a quality multi process Three-phase welder that can provide MIG, MMA and gas less self- shielded welding options.  A high duty cycle (400 Amps @ 100% MIG) and excellent reliability is achievable thanks to the signature Jasic IGBT technology used in their inverters.  Featuring closed loop feedback control: feedback sensors which control the energy delivered to the parts.  This, coupled with a constant voltage input, allows the machine to operate with a wide tolerance to mains fluctuation within ±15%

The Jasic Mig 450 provides excellent welding characteristics due to its self adjusting welding current and voltage. Superb weld appearance and high welding efficiency with a stable arc and low spatter are achieved thanks to unique welding dynamic characteristic control circuits in MIG. With its wire feed interconnections it can be used to weld in a wide radius.  Preferred by many, a separate wire feed unit allows the user to keep the power source from the dirty work environment, protecting it from dust etc, whilst allowing increased mobility to get to the workpiece from a distance.

Providing excellent welding characteristics and consistently reliable performance for both MIG MAG, MMA and Lift TIG welding processes especially for highly demanding and repetitive welding cycles.


One of the many features on the Jasic MIG 450 is Burn Back Control, meaning when the trigger is released, the wire will stop but the voltage potential will stay on the wire to burn it out of the weld puddle.   This feature improves crater fill and hence, enhances weld appearance.

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.

A high inverter frequency greatly reduces the volume and weight of the welder.  A reduction in magnetic and resistance loss enhances the welding efficiency and energy saving effect.  Switching frequency is beyond audio range, which almost eliminates noise pollution.


All Jasics bought from TBWS come with a market leading 5 year warranty, far surpassing all other brands warranties.  Furthermore, Wilkinson Star (UK Jasic importer) operate 3 Jasic dedicated service vehicles around the country.  These vehicles will travel to the work place of an operational machine in the unlikely event of a break down, to carry out repairs and limit interruptions to productivity.  Couple this customer service, the feature packed machines for a fraction of the cost of big brands and great build quality, make these welding inverters hard to beat.  This is backed up by their certified ISO 9001 quality management system and a product range that fully complies with CE,

Suitable for 0.8 – 1.6mm wires.
