TIG Welding Tips And Tricks | Simplified Instructions

Below are some of the main TIG welding tips that can assist both the new and accustomed welders who want to be better to achieve the perfect weld.

Feed the filler rod with ease

Just like we all learned how to hold a pen or pencil in school to write, anybody can learn how to hold a TIG torch with ease by applying these TIG welding tips. Using a thin glove helps as it offers more flexibility to maneuver and at the same time protects your hand as you weld. Others may prefer thicker gloves. The main thing is so long as the user is comfortable, there is no restriction.

Size of TIG welding rod

One of the most basic TIG welding tips is to never use a welding rod that is bigger than the thickness of the metal being welded. For thin metal, use thin rod and for thick metal, use a thicker rod. Example, using a 3/32 rod for welding a 0.03 thick metal does not make sense. This is so to limit the chance of blowing a hole due to the fact that the amperage is low and thus weld puddle needs to be small. However, for beginners some TIG welding tips are, the welding surface or metal should be bigger in width. Practicing on a 1/8’’ thick metal, a bigger rod should be chosen as the bigger the rod, the easier it is to feed.

TIG torch welding angle

The welder should ensure that the TIG Torch is placed at an angle of 10 degrees or less to the surface. Beyond this and the heat will be deflected and lost leading to the rod melting before getting it into the puddle. This causes the rod to form a ball and blob onto the puddle. This is the general rule but there are of course exceptions to this rule. This TIG welding tip is of major importance because the torch angle effects level of penetration as the more vertical you put the torch, the more arc is directed to the welding part.

A ball forming at the tip of the rod

This is a sign that the welding is not achieving its objective as you are doing it in an incorrect way. This may be caused by adopting a wrong welding angle, an arc that is too long, lack of enough amperage for the rod size or all of these at once.

Use the smallest amount of tungsten possible

As one of the TIG welding tips always ignored, Tungsten should be selected according to amperage and polarity. The smallest tungsten should be used but not on all jobs. Just like using a 1/8’’ electrode for everything is amateurish as there are jobs , such as welding 3/16’’ thick aluminum, that are not suited for this. An electrode that is too large can cause contamination and an erratic arc, flaws which can lead to expensive damage. 2% thoriated or lanthanated tungsten electrodes are known to withstand high amperage better than most of the other electrodes on offer. The current should match the electrode size, not too much or too less. Using too much of argon on the torch gas can have a reverse effect and result in a loud erratic arc. These are important TIG welding tips especially for beginners.

Mixing gases is possible

These are vital TIG welding tips for all welders. Argon is the most versatile and widely used gas; however, there are cases where mixing it with Helium gas can result into surprisingly better and cleaner work. Combining equal amounts of the two gases is usually important in welding thicker aluminum and magnesium or pure copper and bronze on DCEN (Direct Current Electrode Negative).
