So, I'm all but ready to fire up my Lincoln 175 Square Wave TIG. I've got the bottle filled and new consumables for the torch. I've got a pile of 1/4" mild steel to practice on... Now I just need to get power to the welder.

I am currently renting so upgrading my garage service is not possible. Since I am not going to use this welder at it's peak power, I've been told by some reliable guys that I can get away using my dryer's 30A service in the laundry room, which is adjacent to the garage. I bought a NEMA 6-50R receptacle for the welder and a 30A plug for the dryer outlet.

Now, my only confusion is what wire type and how should it be wired? The welder only uses three wires while the dryer outlet uses a fourth.

What's the safest way of making a cord to do the job?
