I purchased 4 of these from ebay for a customer I was doing a job for , the job fell through and only used one of them . I am keeping 1 so have 2 for sale . they are great bits of kit for race transporters as you can run your mig welder from these just hooked up to your truck battery ! they are also battery chargers , they cost me £300 each no sensible offer refused . you are welcome to come and see our 1 and how they work , the 2 that are for sale are still boxed and brand new never opened . ring yogi 07976156438
