Basically, this is a cheap Chicago Electric bandsaw blade welder from Harbor Freight. It requires 220V power. But the hot item IMHO, is this 12v car battery powered model [photo after the jump]. Basically it does the same job in a smaller package. Granted, it retails for $50 more than the 220V one, but for those — like many of us — who don’t have 220V in our garages or workshops, this could be a godsend.”
“Breaking and rewelding a blade is sometimes necessary if you’ve got to make an internal cut into something that requires you to thread the blade through, make the cut, and then brake the blade and thread it out. In that sense, I think the smaller battery powered welder might be better as it’s easier to hold by hand, etc. without dragging everything over to the welder like the Harbor Freight model.
“Blade welders overall, though, are a useful tool if you want an easier way of welding a blade (assuming you have a regular welder), or just a way of getting it done, period, if you don’t.”
This definitely falls into the range of tools that I hadn’t thought about owning. I have a portable band saw for the situations where I’ve gotta come in at a funny angle or work in the field, and in the past I’ve used a metal-cutting blade in a recip saw for situations where I couldn’t get the blade around the cut. And I’ve seen one of these in action where I buy my blades. But I hadn’t thought about buying one for myself.
I’d imagine that this falls into that category of tool that might not be bad to purchase from HF — the kind you don’t use regularly enough to put in hard conditions.
And we do have 220V in the TM shop.
