HI CGCINC
I can tell you my PM256 came with a cord attached and a separate plug. The plug I did not use as it was not a standard welder plug. I bought a welder plug and receptacle from Home Depot. As far as making your own extension cord here is what I did. When I built my cart I attached the extension cord to it with two receptacles there. This allows me to have my tig and mig welder on the cart plugged to the cart. I can now wheel the cart around my shop or outside and use either welder for a project. You will also need to attach your gas bottles on the cart too. Use big back wheel where the bottles are attached. Put a draw on it for you consumables, collets and cups ect. Look around there are many different carts that have been made pick one that fits your needs. Some have a water cooler attached too.
Have fun
Tom
