    Default Comparing stick welding- Syncrowave 200 & Maxstar 150 S

    I noticed welding with the Syncrowave the rod does not stick as much as it does with Maxstar. Is this because of the OCV differences.? Also, I had the dig function off while making these comparisons. I was using a 7018 rod.

    Transformer power source versus inverter. Dig should be used for cellulose type rods.

    It's the VA curve. This is good info:

    In the RESOURCES, ARTICLES section, search for "selecting a constant current". There's an article describing this. (I can't link directly until the post is approved.)

    Well they definitely differ in their arc-initiation and arc-stability qualities, offering a nice contrast of inverter vs. transformer stick machines.

    I set my Syncro 200 at 20%+ Dig for 7018 and 30%+ for 6010 to keep from sticking the electrodes. Both light up easier with 80V OCV on the Syncro. The 150S Maxstar tries to compensate for a low OCV ~15V sensing voltage on the cellulosic rods with Hot Start, but can be tough to light off even 6011 on anything but clean, warm metal and a solid ground. I always run it on 230V, same as the Syncro. The 150S definitely doesn't run 6010 very well at all.

    The Maxstar's manual shows a huge amperage jump at 40V so it can sense a close arc and keep the rod going by increasing amperage, this without an inductance (Dig) control button. You can stick the electrode on both, but you can reduce it more with the Syncro's Dig control.

    The Maxstar inverter arc is smoother than the Syncro's transformer arc with both types of rods once lit.

    Interesting. I've had almost the opposite experience/impression with the two machines.

    I say the tranny is a fuzz better on starts, you get used to it and the difference is pretty minor.

    Try to decrease your dig as you weld ive found its better to run no dig because not all welders have that setting
