Setup Guide
Getting Started
If you are needing basic help getting started TIG welding, here are some general settings and selections to get you started. This guide is intended to be
only a starting point, not a completely exhaustive source. Keep in mind that no guide is a substitute for practice and experience. You may find that your
final settings may be different from the ones listed. The following guide does not represent the maximum capability, or even the recommended capa-
bility of the unit. However, it demonstrates what is considered to be a practical capability limit of multiple variables when factored together. It is possi-
ble to weld thicker materials with the same amp range. However, as a best practice, the industry does not recommend heavy passes, rather thinner
“
stacked
”
passes on thicker plate. Multi
-
pass welds are typically stronger, have less defects and require less amperage. On heavy gauge plate, such as
3/8”
up to 3 to 5 passes may be required. Additionally beveling of the joint is required for complete joint penetration, even at higher amperages. The
thickness rating takes into account the
“
heat sink
”
capability of the metal, and the power of the amperage to overcome the conductivity of heat of the
metal used using multiple passes. The position of the weld also influences the amperage, cup size, gas flow rate and tungsten size used. For the fol-
lowing recommendations, these are all in
“
flat
”
position. Modify your settings accordingly. Vertical will require less amperage the more you weld

”.
