How you can TIG Weld Aluminum and obtain the Stack of Dimes Look, Despite a classic TIG Welding Machine

Wanna learn to TIG weld aluminum?

First you’ll need a decent TIG welding machine. Not really a great one, only a decent one. Already got one? You may have a classic Synrowave 300 or perhaps a DialArc, a classic Hobart CyberTIG or you will possess a completely new Burns Empire 200DX.

Understand what? It does not really matter. Exactly the same concepts apply. For those who have a classic as grime TIG welding machine, you are able to still make good aluminum TIG welds. Weld beads that appear to be like a collection of dimes.

First allows take a look at machine configurations:

Set the polarity to someOrd (alternating currrent)

- Make certain to create our prime frequency to continuous

- Set the amperage to around one and something half amplifiers per every thousandths of inch of thickness (as much as about 250 amplifiers then things change a great deal)

- Set both contactor and amperage switches towards the remote positon

- Set the argon or argon/helium torch shielding gas close to 15 cfh. (if you work with a #7 cup) less when the cup is more compact

- Notice I stated argon or argon/helium? Argon isn’t the only game around. Actually, should you TIG weld any aluminum over about .063″ thick, adding helium towards the mix constitutes a massive difference.

Now allows talk tungsten electrodes:

- 2% thoriated have obtained lots of bad press for that radioactivity problem however they will work

- 2% lanthanated electrodes are an excellent all purpose electrode…great for TIG welding aluminum in addition to steel

- Make use of the littlest electrode which will complete the job without quivering at max amperage.

Remote amperage control…you’ll need a feet pedal. Period.

- Once all of the configurations are ok, and presuming you’re welding on 1/8″ thick aluminum, grab a bit of 4043 filler fishing rod in 3/32 diameter (rarely are you going to make use of a fishing rod as thick or thicker compared to metal you’re welding)

- Extend the electrode tip about 1/4″ beyond the tip from the Tig Welding Torch cup and pre purge the gas by tapping the feet pedal.

- Contain the torch just like a large first grade pencil. Touch the end from the tungsten towards the metal after which pull it back about 1/8 inch. Switch your helmet lower and press the pedal to initiate the arc.

- Don’t melt the aluminum immediately though, watch the black stuff prepare from the arcs cleaning action before you decide to melt the metal. Then press the pedal far enough to produce a puddle that’s about 3-4 occasions the thickness from the metal you’re welding.

Now comes the part regarding how to attain the “stack of dimes” look. You receive that with the addition of the equivalent fishing rod by moving the torch exactly the same distance any time you add fishing rod. Add fishing rod, Step ahead 1/8 inch,Add fishing rod, Step ahead 1/8 inch,Add fishing rod, Step ahead 1/8 inch, lather rinse repeat. Should you choose this consistently, you’re going to get evenly spread ripples that appear to be like a collection of dimes.

Obviously it appears not the same as beneath the welding helmet which is harder of computer sounds, but this is actually how you’re doing so. All that’s left may be the doing. It requires practice and a lot of quality chair time.
