    Default TIG welding with shop master

    I have a mig setup for my shop master, How well will this machine TIG both DC and AC, I know its a simple sine wave, I did have an Idealarc years ago that was sine wave and did fine with Aluminum. Will the amps be smooth at low DC output? Also does the panel control set the maximun output then pedel everything under? this machine has not "taps" or ranges. Any help woudl be great

    Yes it will work fine for both AC and DC tig, I used one for years.
    Remember you will need the high frequency box if you want to use it for AC tig welding.
    Yes you can set the dial at the maximum amps you require (or slightly above) and use the pedal (or thumb control) from there.
    For the most part I used to leave my machine dial maxed out. I used a thumb control so with the dial maxed I didn't have to turn the thumb control as much to get to my desired output.
    The foot pedal is easier to get to the max setting, hence my recommendation to set the dial to the maximum amp you require or slightly above (helps form a puddle easier).

    Although he did mention Mig first, he is asking about the TIG function- he already has a feeder for the Shopmaster

    Considering the thread title was "TIG welding with (a) shop master"
    I'd assume he wanted to know what the tig welding qualities are for a Shopmaster.

    It sounds to me like he has it setup for mig right now but knows it can also be setup for tig, he just wants to know if it is worthwhile to spend the money on that, or buy another machine (dedicated tig).

    The Shopmaster machines are GREAT, I only wish they would make an inverter version of the 300 amp AC/DC, CV/CC ,machine. It's a true all purpose work horse, a Swiss army knife of machines, an asset to any shop. I know where I could buy two Shopmaster 300's in great shape... only problem is I don't have the power to run them in my garage (hence wanting it to be an inverter).
