    Default Weld Settings Calculator

    Dynasty 200 DX
    Specs max weld 1/4" (steel or aluminum)
    Welding Amperage Range 1-200 Amps


    Miller Settings Calculator
    Stainless Steel/Steel x 1/4" Fillet Weld
    Recommended amperage range 250-325 (For mild steel increase 10%)


    I know the calculator is for estimates but 50+ amps is a pretty large variation. So what am I missing? All things being equal one of these has to be incorrect??

    You're right that Miller should offer some sort of an explanation where they get their calculator numbers. Sure some people may tig 1/4" fillets at 300 amps using 3/16 filler, but a lot more are content at 150 amps with 3/32 or 1/8 filler. Likewise, the butt weld numbers have to be looked at carefully. Preps are commonly v-grooved with a gap (85-110 amps) as compared to trying to blast through a tight fit-up with high amperages.

    these are just guidelines... to get you in the ballpark..

    everybody has their own unique style that will modify those parameters

    common sense and experience will mold those in real world terms..

    travel speed, torch position etc are all unique to the operator...

    the human variables will widen that range....

    you could accurately calculate these if it were a robotic or machine application where you could controll all the variables.... but people are not machines...
