Some people use Argoshield (mixed gases for tacking etc) but it is not the correct gas and doesn't weld very well. By the same token you do not use pure Argon to weld steel with the mig process, it leaves a very "cold" looking weld that lacks penetration. Use pure Argon in mig for Aluminium only

What kind of welder do I need to weld aluminum?
Get a TIG (tungsten inert gas) welder. This is a type of welder that uses a tungsten electrode and an inert gas to shield the welding area. The precision achieved with this type of welder is crucial when working with aluminum, especially thin pieces.
What is the purpose of argon in a welding machine?
Argon’s purpose in the welding process is to shield. Pure argon is a cost-effective gas solution. 3% helium can be added to increase arc stability. [5] Gas needs to be acquired from authorized gas dealers. Most welding supply stores will be able to provide gas or refer you to an outlet that can.
Where do I get argon gas for a TIG welder?
Pure argon is a cost-effective gas solution. 3% helium can be added to increase arc stability. [5] Gas needs to be acquired from authorized gas dealers. Most welding supply stores will be able to provide gas or refer you to an outlet that can. If you’re renting the TIG welder, purchase your argon canister when you pick up the welder.
What is aluminium welding used for?
Aluminium is one of the more common materials used to weld with, with a few properties that make it unique compared to steel and stainless. It’s soft, so it’s easy to work on and machine, it’s non-magnetic, it’s pretty resistant to rust and corrosion, and it doesn’t spark. That’s why its main use is on aeroplanes and boats.

Why is it difficult to weld aluminium?
Aluminium alloys pose a range of difficulties when welding, including: High thermal conductivity. This results in excessive dissipation of heat, which can make welding difficult and/or result in unwanted distortion of the parts, owing to a larger heat input being required.
What is the best gas for welding aluminum?
argonThe gas for aluminium welding can be argon or helium. These two gases are used pure or mixed. Pure argon is the most popular.
What gas do I need to MIG weld aluminum?
argon shielding gasChoose the right gas: Because aluminum is a non-ferrous metal, it requires a 100 percent argon shielding gas. Flow rates of 20 to 30 cubic feet per hour are recommended.
What is the best gas for TIG welding aluminum?
argonTo TIG weld aluminum, you need straight argon or an Ar/He mixture. Adding helium works great when welding thick aluminum because aluminum dissipates heat quickly and requires a very hot arc.
Is MIG or TIG better for welding aluminum?
Generally, two processes are used for aluminum welding: GTAW (TIG) and GMAW (MIG). Most welders in the business will say TIG is the better option for welding aluminum because it allows for better results on lighter gauge materials. When done correctly, TIG welding aluminum can produce quality welds.
Can you weld aluminum with a regular welder?
Aluminum can be welded using different processes, namely TIG, MIG and plasma. The TIG welding process with alternating current is mostly used for thinner sheets. Butt joints in particular can be welded well with a TIG torch.
Can you use MIG welder for aluminum?
Material thickness: Most reputable MIG machines can be used to weld aluminium down to 3mm thickness. To successfully weld materials thinner than 3mm, it may be neccessary to use specialist MIG or TIG welders with pulse capability. (Note: to TIG weld aluminium, you will need an "AC/DC" machine such as the 202T).
Can I weld aluminum with a stick welder?
Yes, it is possible to weld aluminum with a stick welder. Since it can be messy, the best methods are: AC TIG. DC TIG.
What is the most common type of filler wire?
There are a few types of aluminium filler wire, but the most common ones you can get are 4043 and 5356. Both of these fillers are aluminium alloys, with 4043 containing 5% silicon and 5356 containing 5% magnesium.
How to feed a torch button?
Once your spool is in and the wire is threaded through the drive rollers (which you’ve swapped to U-grooves), you can hold down your torch button and feed it through.
What temperature does aluminium melt?
Aluminium melts at around 660°C, but the oxide layer on top melts at about 2000°C. What that means is that you could be melting the aluminium that’s underneath the surface layer, but you won’t actually be able to start a weld pool until you burn through the oxide.
What is the most common material used to weld?
Aluminium is one of the more common materials used to weld with, with a few properties that make it unique. That includes how difficult it can be to weld.
Why is aluminium hot short?
Aluminium is ‘hot short’, which means that it’s prone to cracking when it’s close to its melting point. Basically, as the weld cools, aluminium is more likely to crack. It usually starts where the weld has ended and will often spread down the entire length of the weld. Cracks in your weld are bad news, and you’ll need to redo it because they’re structurally weak.
Why is it important to clean aluminum?
It sounds like a hassle, but cleaning your aluminium thoroughly is critical because of the metal’s melting points. The arc will still ignite even if the metal is dirty or still has its oxide layer. However, if you leave too much of the oxide layer on the aluminium, you might not be able to start a weld pool.
Why is it important to keep a torch straight?
That’s why it’s super important your torch stays straight, and you also don’t accidentally kink it in your hands while you’re moving around. Even if you can’t see it, the liner in the torch will hold some of those small bends itself even if the torch isn’t bent.
What type of welder is used for aluminum?
1. Get a TIG (tungsten inert gas) welder with AC capability, not only DC. This is a type of welder that uses a tungsten electrode and an inert gas to shield the welding area. The precision achieved with this type of welder is crucial when working with aluminum, especially thin pieces.
How to weld aluminum with a torch?
Move the torch along the welding path. With the torch in proper position, practice moving your hand along the part of the aluminum that you will be welding. Practice with gloves on to simulate the amount of effort required. Make sure to move your entire hand, as getting in the habit of using just your fingers is very limiting.

What angle should a weld be held at?
You will lead the weld with the filler rod, which should be held at about a 90° angle to the torch tip. The torch should always be pushed and not dragged. If the filler and the tip come into contact, your weld will be contaminated and lose structural integrity.
How to make a puddle in welding?
Create the puddle. Melt the workpiece until you create an adequately-sized puddle that’s no wider than double the diameter of your filler. Add just enough of the filler rod to fill in the joint, and then move to the next portion of the weld. Continue until the entire joint is welded properly.
Why do we use a tig welder?
We recommend TIG because it tends to provide some of the most durable welds and when you’re melding two different metals, you want a solid weld that is going to hold up. A TIG welder can do a lot for finding success with this type of weld.
