    I have a blue brand inverta TIG 180p.This welder was bought for me over 10 years ago, and has never been used until a few days ago. It came with a basic instruction book with no set up details. It has slope in & out controls which I assume is the amperage at start & finish, does this also control the gas pre flow? and not sure what the 2T and 4T switch does. The more I look at You Tube the more confused I get. Thank's Yetta

    2T is when the machine only runs with an input from the trigger or pedal, 4T is like an automatic mode or trigger latch
    Slope in and slope out is basically the way the machine delivers the current, so a long up slope will set the machine to gradually increase the amperage and vice versa on the back end.
    Not sure on the gas part of your question.

    2T you have to keep the button on the torch pressed, 4T the button is pressed and released to start then again to stop. Gas will start when you press the button so up slope and pre flow should work together same with down slope to stop cratering.

    Thanks very much for your replies just what I needed. Hope to practice with more confidence now. IMG-20201113-WA0005.jpg

    Had a good practice yesterday, when I am confident I am going to make an exhaust system with 304 s/steel. I have a pack of 316L x 1.6 filler rods which came with my welder, are these good enough to make as perfect a job as possible with regard to corrosion.

    To do a good job on an exhaust system you need to look at purging.
    Basically filling the inside if the tube with shielding gas as well as the outside where you are welding.
    Plenty of videos on that in utube as well :)

    It has pulse, it has slopes - couple that with a decent purge, lots of practice and a decent (comfortable) torch, you should be able to get good results

    Slope in and out or up and down will be the time in seconds to your set amps when you press the torch trigger.
