    Inverter TIG - 110 or 220 preferable?

    If inverter unit will accept either 110 or 220 is there any advantage to using 220 with type? (In my garage 110 has same breaker capacity but standard romex wire whereas 220 is I believe 10 gauge).

    Many of them won't reach full amperage on 120 volt.

    Duty cycle is also affected. Here's the specs for comparison on my Thermal Arc 161.

    Note the reduced amp draw on 240 volts as well.

    Perfect that's what I needed to know. Will check particulars for my unit 1st but would have used 110 for flexibility if there were no advantage. Thanks!

    I am guessing this is the welder you own.,,not the 161STI 110 output on 120 volts input.. The 160 STI have more output power on 120 volts input...

    It's a Simadre 5200D http://www.simadrestore.com/si5250aplcu22.html. I was going to feel foolish if output differences where clearly spelled out in Owner's Manual but they're not. Nor online. Only states that it CAN be wired for 110 or 220.

    Guess I'll wait on response from their customer service. This forum has been 100x faster in responding - thanks all! [Especially appreciate as 1st time poster. If I don't burn down garage I'll be back with a lot of questions ]

    The official response was "performance will be better with 220v". So summarizing for sake of anyone else seeking answer (Thanks all!):

    Yes, 220v vs. 110 does have an impact on dual voltage capable inverting TIG performance but 110 fine for 1/8 or less (possibly 3/16th on a butt joint).

    i have a old Norweld welder and on 240 volts it runs with higher arc voltage . basically it runs better on 240 volts.
    .
    on 120 volts you try to pull 30 amps and the 120 volts drops below 110 volts so cause input voltage is lower the welding arc voltage is low

    I knew with certainty that "old style" welders clearly benefited from 220v. What I wasn't clear on was whether these newer "inverter" type actually benefitted from 220v or if they were current (or otherwise) limited regardless of voltage used. I went ahead and connected to 220 simply as I figured there was less chance of popping a breaker but will keep in back of my head that 110 is always an option if this setup is too limiting. Honestly my skill is going to have far greater impact than voltage for a long time ;-)

    .
    voltage drop on 120 volt circuits pulling more than 15 amps is common. some long extension cords or long wire runs in the walls can cause voltage to drop below 105 volts when trying to pull 20 amps from circuit. the problem of voltage drop is 2x more on 120 volt circuits.
    .
    a welder pulling 25 amps on 120 volt circuit would typically pull 12 amps from 240 volt circuit.

    240 gives better output and duty cycle. Not every location has 240 power. If this machine will possibly get used in multiple locations then get dual voltage, then you're ready for everything.

    I do have dual voltage. That's what I was trying to figure out e.g. would 220 make a difference or if inverter type was internally limited regardless of input voltage.

    Sorry to have added to the confusion. The same machine will have better performance on higher input voltage.
