Just bought a Hobart Tigmate for my projects, nice machine with simple set-up and use. All the parts and manuals are Miller/Hobart. This will just be for home use so I bought it with the fingertip control, all I can say is Wow it is one sweet running machine, on thin rusted material I just turn it down a bit and if the porosity creeps in I use a little stainless wire, eats all those little bubbles right up!
