hey there, does anyone know if it is possible to get locking castor type wheels for the front of a miller 210. I have a house with a slight incline on the driveway and usually stick a 2x4 in front of the welder. today i realized the miller will move down the driveway onto my foot if it feels like it even with the wood in front.

also if a brand or part # was available, that'd be awesome. Thanks.
