140 AMP 120/220 DUAL VOLTAGE WELDER

I can tell you right now, that generally the best size stick machine for around the farm is usually a 230 amp AC / 140 to 160 amp DC. Better yet is a 250 amp AC/DC. My father and I have a Century 250 AC/DC. Been using it for 10 yrs great machine. Beings this machine has such a high amperage on both sides we have a very good duty cycle for any 5/32 or lower rods.

Anyway, post some more detailed information on the machine that you are asking about, then we can actually evaluate it for you.

The 120/240 refers to the supply voltage. It can be used on 120V or 240v. The 140amp refers to the output welding amps and would be the maxmium amps that this welding machine can be used at under ideal conditions.

There should be a duty cycle also listed, like 20% duty cycle. That means for every 10 minutes of the machine being on, only 2 minutes can be used for welding.

It should also say AC/DC or just AC or DC. This tells you what electrodes can be used for welding.

Sure it can be used for farm type welding if it works. Try to find someone that has used a welding machine and get them to help you out setting the machine up.
