    Re: Shortcomings of a DC only Stick Welder

    I am learning and still have a long way to go. I inherited a lincoln buzz box (ac) from my dad. We have some pipe fitters at work and some structural steel welders too. After talking with them i decided i needed a better welder. I bought a used miller cst280 on ebay. Dc only inverter. It is not a be all end all since i would like something that makes a better tig machine. But...man is it nice as a stick welder. I don't miss my buzz box ever.

    Some of the inverter welding machines have low duty cycle, even on the higher end smaller units.
    Something to look out for.

    I have a little Miller Maxstar 140 STR that has a decent duty cycle on 115V it's 100% at 80 amps, on 230V it's 100% at 100 amps. It's a sweet little welder, has a great arc. I understand the 140 models were built in Austria by Fronius for Miller, I know mine says on the label it was made in Austria. It weighs about 10 lbs and is the size of a 4 slice toaster

    Ha...CST280 has a 100% duty cycle at 150 amps. I don't think duty cycle will be an issue with that one. "Designed for Stick/TIG welding pipe and plate in the construction industry, this small, durable, goes-anywhere welder delivers 280 amps of superior Stick performance"

    It does good on bagels, just takes a little longer than sliced bread. Name:  ImageUploadedByTapatalk1447285121.429903.jpg
