TIP #1 The single greatest tip for Tig welding aluminum castings is to utilize a helium/argon blend rather than straight argon. That is a really impressive assertion, yet I stand behind it 100%.

A 50/50 argon/helium blend works perfectly thus do blends that contain up to 80 percent helium. Helium adds more energy 3104 aluminum plate supplier to the circular segment and has more effect on weighty aluminum than some other welding procedure you can imagine.

Did you had at least some idea that a tig welding circular segment conveys more voltage with helium gas without adding more current? It’s a reality.

Have you at any point illuminated on a weighty aluminum projecting utilizing straight argon gas and needed to stand by a truly lengthy timespan to try and get a puddle? Not so when you add helium. You get a puddle right away and it’s even a cleaner puddle… a special reward.

Welding reading material suggest straight argon for anything short of ¼ inch thick aluminum. However, I’m letting you know that once you utilize an argon helium blend, I will bet you won’t have any desire to utilize straight argon again with the exception of truly meager aluminum sheet.

TIP #2 The subsequent tip is to preheat the aluminum projecting. A 200 degree preheat will make all the difference and in the event that you are utilizing a little tig inverter like a Mill operator Tradition 200dx or a Lincoln Invertec v205t, you just have around 200 amps to play with and you will require all of it. A preheat will get you past the halfway point.

It doesn’t exactly make any difference how you get the part hot…A propane light or old gas barbecue both work perfectly.

TIP #3 The third tip is to be mindful so as not to utilize an excessive amount of light gas. Just honestly, that is the gas emerging from the tig cup.

That’s it and more is more awful , worse. Utilize barely sufficient stream to safeguard the puddle and not considerably more. Assuming the commotion from the curve is shaking your minds out, you presumably have an excessive amount of gas stream. Consider it, how could you need to blow cool gas on something you are attempting to warm?
