I don't see this as being used for production welding, at least in cordless mode. You're not going to replace an engine driven unit for field pipeline welding or something. But for certain applications, it could be ideal. For example, in my business occasionally small repairs need to be made in the field, or otherwise outside of a work station with a conveniently located welding power unit- a weld that needs a minor touch up for undercut or a pinhole repair, a small bracket needs attached, etc. The welding itself is very very minor, but the logistics of getting the right equipment where you need it can be a huge pain. Engine units aren't always an option inside, there may or may not be proper power readily available for a standard machine, you may need to work from a manlift, whatever. You spend two hours setting up for three minutes of welding. Something like this, wherever you can carry it, you can use it, for a time at least. Also for maintenance work, where small amounts of welding may be needed to, say, weld a few pieces of unistrut to a beam for hanging conduit while working from a lift. Not exactly production welding, but can be kind of a pain to get more traditional welding equipment where you need it, depending on the facility. That's where I see this shining. It's not for everything or everyone, but it has its place I think.
