Full product details
Jasic Multi Process MIG Welding Machine – 450 amps JM-452S Pictured is the air cooled version which you can see includes the benefit of a storage draw where the water cooler would be if you had one. 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.
