I bought a Hobart this year, on sale at the tractor store. uses the flux core wire.
.030 wire I think, The grandson has good eyes and a steady hand and loves to weld,
The neighbors gave us some trampolines, the top tubes around the safety net were coverd , so they are smooth like crome and just the right size. The welder loves to weld
galvanized , the smoke doesn't bother it since the welder doesn't depend on any gas
shield. Grams won't let us weld in the garage so the small amount of smoke it may make is lost outside.
