Seems as I'm getting lazy and grabbing the plasma cutter, nuttin' fancy but dang it's handy.
I love my 50 amp plasma cutter, but there are some things that just require an oxy-acetylene torch so I will keep it around also. Also some things cut better with a port-a- band saw like cutting square corners off small square tubing, so lets keep one of those handy also. Sometimes it is just easier to grab a 4.5" grinder with a cut-off wheel(also one with a brush, one with a sanding disc, one with a hard disc) for those little cuts, so I keep one of those handy also. A chop saw is most useful when needing to make a square cut on any material, so better keep that tool also.
I am just saying that a good welding shop needs a plasma cutter, an oxy-acetylene rig, a chop saw , a port-a-band and 4.5" grinders to be really prepared for any situation.
