RHC: Bob, Hobart make a professional quality MIG welder that is as
professional as it gets. It sells for about $1100 new, but is used in
factories extensively for up to 100% duty cycle. I have used mine for
years and takes the place of my computerized Lincoln for most jobs. It
is 110, and draws about 20 amps at maximum capacity. But it is
professional quality equipment so it never overheats. It will weld all
day up to quarter inch, but will weld up to 3/8 inch steel too when
needed

At the moment I am in Florida, so I cant give you specifics about the
model etc, but it should be possible to locate it through Google.
