Im looking to get a cheap stick welder so I can make this new hobby of mine I know a couple of retired boilermakers and wanted their advice on brands etc but we didn't get that far because they were adamant that it would be virtually impossible to weld bicycle frames with such a welder without blowing holes. Now everyone on this forum is quite adamant that these welders would be fine, and I believe them, because they have the anecdotal evidence.

But why would these boilermakers be so sure it wouldn't work? Could it be a difference with our standard power (240v, 10 amp) here in Australia? Or maybe they imagined trying to complete a whole weld at once? Do I need to find really old bicycles with thick tubing to make it work?
