any name brand 120v welder will weld anything on any old truck in one pass
i bought a 120v lincoln weldpack 100 at home depot they also carry consumables there
it is usually the weldor (person) not the welder (machine) that determines that the 120v machines can't weld
welding takes practice and experience, don't expect perfect beads 1 hour out of the box
i may be the odd duck in that i use a 120v lincoln fluxcore welder to build my 58 truk
including welding in a mustII cross member and
lots of body panel repair
