  • Set the argon or argon/helium torch shielding gas to around 15 cfh. (if you are using a #7 cup) much less if the cup is smaller.

  • Discover I stated argon or argon/helium? Argon is not the only game in town. In reality, if you TIG weld any aluminum more than about .063" thick, adding helium to the mix makes a huge difference.


    • Now lets talk tungsten electrodes


    • two% thoriated have received a lot of bad press for the radioactivity problem but they do function.

    • two% lanthanated electrodes are a truly good all objective electrode...good for TIG welding aluminum as properly as steel.

    • Use the smallest electrode that will get the job completed with out quivering at max amperage.


    Remote amperage manage...you want a foot pedal. Period.


    • As soon as all the settings are ok, and assuming you are welding on 1/8" thick aluminum, grab a piece of 4043 filler rod in three/32 diameter (rarely will you use a rod as thick or thicker than the metal you are welding)

    • extend the electrode tip about 1/4" past the tip of the TIG torch cup and pre purge the gas by tapping the foot pedal.

    • hold the torch like a huge 1st grade pencil. touch the tip of the tungsten to the metal and then pull it back about 1/8 inch. flip your helmet down and press the pedal to initiate the arc.

    • don't melt the aluminum right away even though, watch the black stuff cook away from the arcs cleaning action before you melt the metal. Then press the pedal far sufficient to generate a puddle that is about 3-four occasions the thickness of the metal you are welding.



    Now comes the component on how to attain the "stack of dimes" appear. You get that by adding the very same quantity of rod and by moving the torch the very same distance each and every time you add rod. Add rod, Step ahead 1/8 inch,Add rod, Step ahead 1/8 inch,Add rod, Step ahead 1/8 inch, lather rinse repeat. If you do this consistently, you will get evenly spaced ripples that appear like a stack of dimes.

    Of course it looks different from underneath the welding helmet and it is harder than it sounds, but this is truly how you do it. All that is left is the performing. It takes practice and lots of top quality seat time.

    It hasn't always been the case but these days Tig welding is 1 of the most utilized welding methods utilized in the metal market. There are numerous factors for this but there are a couple that stands out much more than others.

    What is Tig Welding? Tig Welding is the new superstar when speaking about manual arc welding. Top quality and standards is acquiring larger focus for daily. And the safety query becomes a lot more essential than ever. With a Tig welder you get the highest high quality feasible to the weld. Tig is also referred to as GTAW (Gas Tungsten Inert Gas) and it is a welding approach where you use an inert gas, typically argon to protect your weld puddle from contaminations throughout the welding procedure. tig welding machines, tig welding machines, what is tig welding
