Tig welder setup

Tungsten Inert Gas TIG Welding is the ultimate in welding, it takes a lot of practice and you need specific welding equipment to do it well.

TIG welding requires a slightly different safety setup than other arc welding processes. Obviously, you should still wear proper welding apparel and boots to protect yourself if the molten piece of metal does drop on you. You will also need gloves for TIG welding. So, using goatskin gloves works better for TIG. They shield your hands from the hot arc, but they offer improved finger dexterity for better TIG torch maneuverability. Since TIG welding allows very low amperage output as low as 5A on some welders , the TIG welding helmet must be sensitive enough to auto-darken on such a low-powered arc.

Tungsten Inert Gas TIG welding is the process in which an arc is formed between a tungsten electrode and the workpiece to join the metals together. A filler rod is often fed into the weld pool by the operator to create a weld. A shielding gas is also required to protect the weld from atmospheric contaminants that could cause weld defects such as porosity. TIG welding is considered the most challenging type of welding to learn as there is a lot more room for human error. There are several different types of tungsten, each with their own unique properties and limitations. The tungsten that best fits your job will mainly depend on your parent metal and application, as not every tungsten will work with every metal. Each type of tungsten comes in a range of diameters so that you can do precise and appealing welds. A good rule of thumb is the thicker your workpiece, the thicker your tungsten and vice versa. You can also check out our tungsten selection guide for the full rundown on each tungsten. Before you start, make sure that you are prepping the non-coloured end of your tungsten. The tungstens are colour coded because they are almost identical in appearance.

We've not used pulse at all in the tutorials and it's best switched off while you get the hang of technique. An earthing clamp should be present and attached to your workpiece or, as in the picture below, the bench. CO2 is the best type for welding, tig welder setup.

The basic information on this page should be a good starting point apart from for specific joints where alternative set up is detailed in the relevant tutorial page. For welding steel the tungsten should be ground to a long point with the taper length about 2 or 3 times the diameter of the tungsten. See DC Electrode Preparation. The long taper and sharp tip improve arc stability. For a butt weld or open corner weld the stick out would be about mm.

In the world of welding, Gas tungsten Arc Welding is considered the gold standard for producing clean, precise, and visually appealing welds. However, the key to achieving these high-quality results lies not only in the skill of the welder but also in the setup and maintenance of the TIG welder itself.

T ig welding can produce beautiful looking welds, and more importantly, x-ray quality deposits on some of the most critical welding applications. For the beginner it may be a very intimidating process. Selecting the right tungsten type and size , cup size, and shielding gas and gas flow can be a daunting task. Below is a quick guide for selecting the right items for your tig welding. This is basic set up information, if you have questions please leave it in the comments sections. Carbon steel, stainless steel and aluminum can all be welded using pure argon shielding gas. This helps in welding aluminum and copper alloys.

A balled tip is usually recommended if you are using a pure or zirconiated tungsten and welding aluminium. With clean metal you can select more penetration and the machine will spend more time penetrating work negative part of cycle. Slope Up only used with torch trigger operation. So, it uses the resistance to the flow of electricity to heat and melt the base and filler metal. When the tungsten is ready, carefully place it in the collet and tighten everything in place. More by the author:. Practice so that welding on all joints in all positions becomes second nature. Some complex joints may require a higher flow. The filler rod will melt and flow into the weld pool. A tungsten electrode is required when TIG welding and this is inserted into the welding torch. You are aiming to push the filler wire into your pool to make the best weld. Its purpose is to regulate the gas pressure gas flow rate released from the gas bottle. Gas Equipment Menu Ad 1.

TIG welding requires a slightly different safety setup than other arc welding processes. Obviously, you should still wear proper welding apparel and boots to protect yourself if the molten piece of metal does drop on you. You will also need gloves for TIG welding.

Setting up the TIG welder is relatively simple once you grasp the basics. The size isn't too important as you can sharpen it to a nice sharp point or a duller point to give really precise control of the welding arc. Gas Cutting Accessories. This closed circuit causes the welded metal to melt because it heats due to electrical flow resistance. Just like with your tungsten, you want your filler rod size to fit your workpiece size. The most common tungsten shape to weld stainless and mild steel with is pointed, which produces a focused and stable arc, and works for all DC applications. To the argon regulator connect the hose of the WP torch, you might need to either find the proper fittings to connect it or cut off the existing fitting and fit the hose directly to the regulator using a barbed fitting. Tungsten Electrode mm: input your tungsten width here. Traditional TIG welders have a fixed frequency of 60Hz, the TIG advanced technology allows AC frequency adjustment from hz, as you turn up the frequency the width of arc from tungsten decreases allowing more control of weld pool and an increase travel speed The pitch noise of weld will increase when AC frequency is turned up, this is normal. CO2 is the best type for welding.
