Bet Mig 250

[Harry in Ky]

I've been trying to find some information on a Hobart Beta Mig 250. It seems most people who know the machine thought they were a pretty good machine in their day. I saw an ad for one for sale, $200. The ad says it runs(whatever that means), wirefeed works but won't strike an arc. He thinks "the hi low switch might be bad" Does that sound like a reasonable assumption or just a fish job? Someone out there must be familiar with these machines. Any thoughts?

Could be as simple as the Contactor or as complex as a bad Transformer. May have a bad connection inside on the ground. You would have to have it tested. A transformer would run about $600.00 last I looked for a Miller.

As for hi/lo setting: mine has a copper bus held by wing nuts (by the wire drive spools) and you loosen and move from hi to lo terminal.
