Wanna learn how to TIG weld aluminum?

First you need a decent TIG welding machine. Not a great one, just a decent one. Already got one? You might have an old Synrowave 300 or a DialArc, an old Hobart CyberTIG or you might have a brand new Miller Dynasty 200DX.

Know what? It doesn’t really matter. The same principles apply. If you have an old as dirt TIG welding machine, you can still make good aluminum TIG welds. Weld beads that look like a stack of dimes.

First lets look at machine settings:

Set the polarity to A/c (alternating currrent)

- Make sure to set the high frequency to continuous

- Set the amperage to about one and one half amps per one thousandths of inch of thickness (up to about 250 amps then things change quite a bit)

- Set both the contactor and amperage switches to the remote positon

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

- Notice I said argon or argon/helium? Argon is not the only game in town. In fact, if you TIG weld any aluminum over about .063″ thick, adding helium to the mix makes a huge difference.

Now lets talk tungsten electrodes:

- 2% thoriated have received a lot of bad press for the radioactivity issue but they do work

- 2% lanthanated electrodes are a really good all purpose electrode…good for TIG welding aluminum as well as steel

- Use the smallest electrode that will get the job done without quivering at max amperage.

Remote amperage control…you need a foot pedal. Period.

- Once all the settings are ok, and assuming you are welding on 1/8″ thick aluminum, grab a piece of 4043 filler rod in 3/32 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 welding torch cup and pre purge the gas by tapping the foot pedal.

- Hold the torch like a big first 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 though, watch the black stuff cook away from the arcs cleaning action before you melt the metal. Then press the pedal far enough to create a puddle that is about 3-4 times the thickness of the metal you are welding.

Now comes the part on how to achieve the “stack of dimes” look. You get that by adding the same amount of rod and by moving the torch the same distance each 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 look 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 really how you do it. All that is left is the doing. It takes practice and lots of quality seat time.

Tig welding is one of the finest welding processes and it has been used in many industries and applications due to its versatile welding process and accuracy. It uses tungsten electrode as a consumable and it is available in different types. In this article, we are going to deal with some tig welder selections such as choosing, setting and some more tips so that when you buy this welder, it might seems to be an easy one.

Welding is a not like other jobs and it is called as a skilled art and it needs lots of practice and patience. We all know that tungsten inert gas welding is used for complex and stylish process and the welding machine used for this purpose is called as tig welder and in this article, let us deal with various tips on tig welding and tig welders. Using tig welding machine is not so easy and pick up the electrode for the mission you start. Crush the electrode to a position and aim for a sharp tip so that it becomes more rounded as you weld. Put the electrode into an electrode holder that has the tip about 1/4-inch away from the cover and go for the settings on your tig welding machine. AC, DCEP and DCEN are the three important ones and prefer AC for aluminum.

Position the air on to five seconds and turn the max amps to 250. Also turn on the gas and different gases are used for different metals, for example, use pure argon for aluminum and use argon and carbon dioxide mix for steel. Brush your welding table or level piece of sheet metal with a wire brush so that it will be clean and flat. Welding Gears are essential during welding and the welding safety gear includes goggles, apron, hood and gloves. Make sure that you have all these welding gears so that you can weld safely and as said above, a clean place is essential so that you can work in a safe environment. Holding the electrode is considered while doing the tig welding. Grasp your welding electrode in your hand that is dominant and start your welding project. Ensure that every setting is proper and make sure that they are not changed or wrongly adjusted.

Choose tig welders count while doing tig welding because only a proper welding tool can improve the performance of welding process. Counterpart the metal type you want to weld and for case, if you require a welder that are proficient to weld hard metals like steel, cast iron or bronze, then only an alternating current (AC) welder can work well. AC welders operate using electricity that “alternates” direction back and forth. For soft materials, DC welder is strong enough to weld and it creates a stable arc for welding. Make your mind up on how thick of metal you are going to weld and based on the thickness, select high amperage or low amperage welder.

Duty cycles comparison is essential while buying welding machines and compare the duty cycles and it is a term that indicates how long the welder can operate. Select a tig welder that you’re your budget and in general it costs from Make certain the tig welder fits your budget. 0 to ,500, and the rates vary depends upon the power and company. While buying it, compare the features and warranties so that you can be able to get the best welding machines in an affordable price.

In this article, we are going to see all about tig welders, but not its process and uses. We will see how to set up, buy and choose this welding machine. Find out a welding supply stores who are specialized in dealing with this machine and look out some classifieds so that you can have an overview on the details of its sale and information about it. Don’t ever go to welding product shop without knowing any information about the products that you are going to buy because some dealers may try to cheat you. So know the history and uses of tig welding machine through internet and through eBay. Visit some online retailer shops and ask your queries to them and they will clarify all your doubts regarding the welding products.

Decide the manufacturer of tig welders and select the manufacturers who are best in dealing with these products. Next we are going to discuss on how to choose a tig welding machine. You need to familiarize yourself so that you can choose the quality ones that are capable of working with different gases. The welder you choose and metal type should match and it should be strong enough to weld materials that are hard and thick. Plug in requirements are there and different machines require different plug in set up and select a machine based on your work type so that you can easily accommodate it. Duty cycle requirement is very essential and many of you are not aware about duty cycles. It is nothing, but indicates how long the machine can operate without overheating during frequent intervals.

There are different power tig series are available and while choosing it give importance to features and most of the types comes with features such as high frequency arc, automatic fans, digital settings and more. Select a manufacturer who can give you the quality welding machine with years of warranty because the machine without any warranty is not good to select.

In this article, we are going to discuss the use of tig welder and before going into brief, let us see a small introduction about the tig welding and its advantages. When you give importance to the appearance of products, your choice has to be tig welding and it may not be suitable for some welding requirements, but it has many advantages than other welding products. In this welding method, the welding arc is created between the electrode and the metal that is going to be welded. Generally the non consumable electrode called tungsten electrode is used due to its high melting point and good electrical characteristics. To weld any metal some sort of heat is required and that heat is produced by the arc and after that the shielding gas is fed through torch.

Some tight form of bonding is required and that type of tight bonding is produced by tig welding and it meets the high quality and code requirements. The tig welding process affords a better and quality welding than its competitive welding process called mig welding. When you go to a shop for selecting TIG welders, you should be familiar with the power and sophistication of your job. You should calculate the volume of the job so that buy a tig welding machine based on your work requirement. Most of us will be in a confused state of mind while selecting the power source and will be thinking whether to use DC power source or AC power source. Metals like aluminium and magnesium can be welded by using AC output, whereas metals like steel and stainless steels need DC output. It is advisable to buy a tig welder that is combination of both so that you don’t need to run for any ac or dc source.

In market, you can find five tig welding machine series and each type are of inverter type that is Infineon IGBT. You need a 220/240v to run this machine and it typically used in all setting like steel fabrication, general repair, light fabrication, commercial repair and in many industrial uses. The best features of tig welding machines are its portability and user convenience and you can get smooth arc characteristics with good puddle wet. You can take these welders anywhere and can easily connect with torches and accessories. The users will be warned by alarm signal whenever it exceeds its applicable current limit by it’s over current warning facility. The consumables and other accessories get longer life time due to post flow timer.

You can see the settings digitally because it has digital readouts so that the users can readout the settings and controls accurately without any mistakes. You can use these welders in all types of industries where accuracy and appearance is needed and these machines are sold out in market with affordable price and warranty, but you need to select welder’s shop that sells this quality and efficient welding machine with good price and warranty.
