mg bodywork and ? mig welder

[code5 <code5@ibm.net>]

Hello--
Has anyone had any experience with the Sears Craftsman 85 amp gas
shielded mig welder on mg frame and/or sheet metal repair? It's
advertised to handle 24 ga to 3/16", which should include the 16- and 20
ga metal on my mga. I'm looking for the least expensive rig that'll get
the job done, but I've seen & read references to 100+ amps being
necessary. I'd even get a stick welder, but I guess I'd burn holes in
the sheet metal.
Thanks for any info.
