I bought this at the same farm auction that I bought my arc welder a number of years ago. I haven't used it but I thought I might see if it is any use to spot weld sheet metal together. Has anybody ever used one of these?

If my memory serves me right, that is more of a heating torch than a spot welder. when plugged into the welding machine the two carbon rods are turned toward each other to create an arc. It should be a very bright arc and produce a lot of heat. It may be possible to spot weld with it, if the amperage was turned very low, but I think it was designed more to heat metal than to do any welding with it.

I guess that explains the name, Forney Arc Torch. I wonder what the practical applications would be for this tool? I'm thinking that the heat from this would be harder to control than a gas torch.

They work well when welding or should I say brazing and trimming cast iron. When welding steel, the carbon rods do add carbon to the base metal making the welds hard and prone to cracking. The one I have has not seen the light of day for 40 years. Company gave it to me cause it just wasn't a viable welding tool. The reality of it is, it will make a neat conversation maker while hanging on the wall with little usability.

Open your own drive-inn theatre, use it for the light for the film!

we use them at the ship yard to cut heavy plate , sloppy cuts at best but it cuts quickly also use them to gouge out welds when replating barge hulls , we use dthem to heat lead crucibles for casting too .
