Selecting the right FILLER RODS FOR TIG WELDING:
Filler Rods are essential to TIG Welding because the filler rod is fed into the molten puddle by
hand filling in the puddle to create a stronger metal bond or puddle to join two metal pieces. It is
extremely important to have the right filler rod based on the metal you are welding. It is also
necessary to have the right
tungsten to insure you are properly setup to weld your metal.

Longevity offers quality filler rods at affordable prices. Please take a look at the selection of
filler rods that we carry to decide what the best application of rod will be for your weld.
Your choice of filler rod is extremely important to the strength and matter density of your weld.
You can determine the diameter of the filler rod needed, by the thickness of the material that you
will be welding. Here are some pointers in deciding how to choose the correct filler rod for your
weld.
1. 4043 is a general filler rod for most aluminum welding. Remember, the TIGWELD 250
EX is strictly DC welding so aluminum is not possible with the use of Argon.
2. 5356 is perfect for 5xxx series aluminum. If you are planning on anodizing the finished
piece, this rod should be used for the weld.
3. ER70S-6 is designed for welding mild steel.
4. ER70S-2 is recommended for welding 4130 chrome moly tubing in most applications.
