    AC TIG Puddle Won't Form

    I have inconsistent results establishing a puddle for AC TIG on aluminum using a Syncrowave 250. I have tried the following to remedy the problem:

    * Different sized cups
    * Adjusting HF dial
    * Cranking up...

    Welder settings with 5356

    I have a MM211MVP that came with a spoolmate spool gun. There are settings for 4043 wire on the chart in the door but I have never found them (on the door, searching online...) for 5356 wire.

    Does anyone know where to find them? Even a chart from another welder that shows both 4043 and...

  • Stainless, aluminum or powder coat for outdoor use??

    I'm looking to do a few outdoor projects and I'd like them to look good and be maintanance free for years! I'd really like to have a bare metal finish and not have to deal with clear coating or powder coating, however, as I read more and more into different materials, I'm not sure this is a realistic...

    Hello millerwelds forums! I'm hoping someone out there can help me get AC frequency up and running on my syncrowave 210. (My machine doesn't have the spoolmate capability in the bottom left corner, so it's not the latest model)

    Here's the scoop:

  • tungsten stability ac tig aluminum problems

    Ive been doing a lot of aluminum tig work lately with a Syncrowave SD 180 which i had thought was (and according to specs is) a bit under powered for 3/16" and 1/4" plate. Ive recently got a helium argon mix to get a bit more heat at the weld which is working really well. I no longer need...

    Green vs Purple Tungsten

    I have recently learned that using green tungsten in an inverter machine is a no-no. I have been welding for over 15 years and I have never heard this until now when I purchased a Dynasty 700 machine. I have used the purple for a while and I am not very fond of it so far. I started using the green again...

    I got machine, used, approximately...
