I also don't know about what a good splice would be. I would imagine that properly sized wire nuts (Scothchlocks or equivalent) would work. To be really safe, you could make the connections inside of a metal electrical box and make sure that you ground the box. I'm not familiar with 220v dryer plugs, but newer designs should include a ground wire. You can put a plain metal cover on the box.
You should also use strain reliefs on both ends.

I have fixed more than one extension cord with wire nuts and electrical tape, but you have some heavy duty stuff here.

It would be easier to get 10 ga UF 3 wire plus ground cable to make the extension. Otherwise you have to keep the wires together somehow.

Depending on how your house is laid out, it might not be that difficult to just run a circuit from your fuse box. If you can use flexible cable rather than conduit, it could be fairly straight forward. You can find electrical code books at the library.
The feeder line to the garage is BX and is wired in just like a permanent installation. It goes into a metal junction box where it is connected to the dryer cord with wire nuts. The dryer cord does have a strain relief where it exits the box. It functions like an extension cord. I would have wired the line directly to the main panel but there is no space. I'm Ok with this set-up for the limited time I will be using the welder, especially since duty time is very limited with this type equipment. If I were going to run something with a longer cycle time (such as a compressor) I would not use this set-up.
