Welding Tips and Tricks

Hell fellow welders! I recently purchased an old Lincoln 70 amp/115 volt 3 in 1 welding machine (model 111-092) for practice for when I don't have access to a more powerful welder. I have tried to look up info on this particular machine but all I could gather was that Lincoln discontinued this model some time ago. So can you guys tell me what this machine is capable of doing?

It makes a pretty good boat anchor...

Seriously, the "capabilities" listed on the machine are a mix of marketing bullshit and general "real world" useless.

You "might" be able to weld with a 3/32 6011 rod, but that OCV will make it a hard start.

Row boat anchor, or door stop.

Sorry, but that's the honest truth.

Sorry mate but this thing is practically useless.
Try some 3/32 6013 and see if it will run them. That is the easiest rod for a machine to run that you can find.
If it does not run that properly, paint it blue and toss it in the sea.

Hi, Ringii99. A rule of thumb for a stick welder is to set welding amps to the decimal equivalent of the electrode size x 100. Doing that math, a 1/16" rod needs 62 (or so) amps, right at the limit of this machine. Unfortunately this greatly limits the functional capabilities of the machine.

So what _is_ it good for... thin guage steel. Even then you'd be subject to the stick welding learning curve (pretty steep ). I'm sure if you got good enough to strike and maintain an arc with it you could walk up to any machine anywhere and strike an arc!

If you purchased it recently that probably means 'yard sale', and that hopefully means it was cheap. If you're looking for a welder with some guts behind it you may be able to find a 220v buzzbox welder that will have a wider range of abilities.

But if you can find rods/electrodes for it, carbon ones, it may turn out to be good for brazing.
