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. It's more costly to get into than other welding processes. This welder will only be able to weld mild or stainless steel but is a really inexpensive way to dip your toes in it to get some practice with the hand eye coordination needed to do TIG weld. To TIG weld aluminum an AC power source is needed as DC power can cause too much penetration and the AC power alternates the current to provide a cleaning action and there are other reasons that you can look up. We call this type of TIG welder "Scratch Start" because to initiate the arc for welding, the electrode needs to be "scratched" or striked against the work piece to start. Expensive welding machines use either lift start or high frequency to initiate the arc. However there are times when even on the fancy welding machines scratch start is still used such as when welding on or around sensitive electronics.

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. There are a few different ways to prepare your tungsten, and different shapes will give different results on different applications. A balled tip is usually recommended if you are using a pure or zirconiated tungsten and welding aluminium. This is a pretty easy shape to make, as you simply set your machine to the recommended amps on AC, turn it on, and the tungsten will automatically form a ball on the tip. This tungsten preparation method happens after you have set up your gun and machine, though, not before.

Some basic parameters are consistent to all TIG welding whereas many other functions may only be available on higher specification machines, tig welder setup. TIG welding requires both hands.

Becoming a welder takes quite a bit of practice, and that includes setting up the welding machine. Certain machines are better for certain methods, so knowing the nuances of each system is important. In fact, your next step is installing the designated collet before screwing the back-end cap into place. After you attach the gas cup to your torch, you can set it aside for now. Start with the torch, gas hose, and regulator.

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.

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. The TIG is an arc welding process. So, it uses the resistance to the flow of electricity to heat and melt the base and filler metal. The power source your TIG welder sends electricity through the TIG torch, which goes through the welded material and flows through the ground clamp back into the welding machine.

The tungsten will take longer to cool from higher amps, and a rough rule of thumb is to increase post flow time by 1 second for every 10 amps. Order by 3PM. Some people like thin tig welding gloves for welding so you can have a lot of control. After the arc is started the output current will increase from the start min current to base main current in time selected by slope-up. This is a pretty easy shape to make, as you simply set your machine to the recommended amps on AC, turn it on, and the tungsten will automatically form a ball on the tip. You can also set the following: Pulse width — This is how long the pulse will last and on the Tig we used above can be set between 0. If your torch is angled too far or is too far away from your workpiece creating a long and unstable arc , you will likely have a weld with much more oxidation. This enables you to set a time that that when you stop welding the machine will slope down to minimum amps you have set on control panel in the time you have set on slope down control. Cutting Discs. Start with your tacks.

Start with the torch, gas hose, and regulator. Safety Equipment Menu Ad 1. This is great for when you need to weld in tight spaces. Ad space 1 MIG - Our best ever selling welder The leathers will not only protect your skin from the heat produced by welding but they will also protect your skin from the UV light produced by welding. The rate might be increased slightly to compensate for drafty conditions. Do not confuse AC frequency control with pulse frequency which I will cover next, this is for pulse welding. For welding today we will be using an R-Tech Tig Tig Welder which is a fully featured Tig Welder and in the picture below you can see the front panel with a description of the controls and what they actually do. Establishing the arc with foot pedal operation. Welding Fume Extraction. ER70S-6 Excellent for multi-pass welds on thick and thin steel.
