This 450 amp machine is the bigger brother of the 350 version and comes with all the same benefits but is suited to the heavier industry. Subtle changes internally like the wire feed motor being upgraded are not so noticeable but the most critical difference is the duty cycle being 100% at 400 amps! If you are looking for a beast of a machine then you might have just found the right machine for your business. What is more, you will be covered by a 5 year warranty with any Jasic machine bought through Sultani Gas. To make it really simple, we register the warranty for you all you have to do is carry on making money and if your machine was to fail there is a small fleet of Jasic field engineers who will come to you to get you back up and running. **Key Features** Burn back control Wire feed button Advanced control circuitry (less spatter, more stable arc and better weld appearance) 4 roll feed unit Variable inductance Gas test function Water cooler **Technical Spec** Input Voltage 400 V AC (3 Ph) 50/60 Hz Recommended Input Fuse 45 A Current Range 60 – 450 A Voltage Range in MIG 15 – 40 V No-Load Voltage 72 V Wire Speed (m/min) 1-18 Duty Cycle @ 40°C 400 A @ 100% MIG (80% MMA) Wire Spool Size 300mm Dia.
