Choosing The Right Tungsten for TIG Welding

Buying a new TIG welding machine can be a purchase that is definitely worth your money. With this type of machine, you can complete a wide number of different amazing projects. If you want to be certain that you are using this machine in the best way possible, however, you want to be sure that you are choosing the right tungsten for the job. Below, our team at Canaweld will explain a few types of tungsten you can buy and what their purposes are. 

Choosing The Proper Colour

Each welding electrode for a TIG will be assigned a specific colour so they can be easily identified for certain types of use. There are specific benefits that come along with each one, and certain types can be used to maximize efficiency and effectiveness.

Green Electrodes

Green TIG welding electrodes are made of 100% pure tungsten. They are most commonly used for AC welding for magnesium and aluminium. These types of electrodes are less expensive in comparison to other ones on the market today, which is why they are so popular in the welding field. Unfortunately, the lower price does come with a cost — and that cost is a faster burnout time. If you decide on this electrode, be sure you stock up on more than just one.

Red Thoriated Electrodes

This, like the green TIG welding electrodes, is a very common tungsten in the current market. These electrodes are mixed with 2% thorium (with the rest being tungsten) and are much more durable and multifaceted than green TIG welding electrodes. These electrodes can be grinded at the tip to create a sharp point, enjoying a long lasting, stable arc. The thorium in this product also allows for a higher current capacity than normal.

Orange Ceriated Electrodes

Looking for a replacement for thoriated electrodes? How about something for a smaller project that is done at a lower temperature than normal? If so, orange ceriated TIG electrodes are exactly what you need. 

These products contain around 2% of ceriated and are perfect for projects that involve DC welding. This type of electrode can weld materials such as stainless steel, titanium, nickel alloys and carbon steel. In general, ceriated is not advised to be used for welding at higher amps as the heat can mess with the composition of this electrode. It is best to use this type of tungsten for smaller projects with precise parts & thin metals.
