GTAW or TIG Welding Calculator

  brought to you by Texas MetalCraft

This calculator is based on a set of TIG Basics that was written (or compiled) by Ernie Leimkuhler of Stagesmith. The code was developed by my good friend and partner, Derek Kennedy (DR Micro Ltd.). Any errors are my responsibility and should be reported to me....webmaster@randyray.com

Minimum Amperage Calculator - Note, all calculations are approximate - your mileage may vary.

- Start by selecting the type of material

   Carbon (mild) Steel       Stainless Steel      Aluminum       Copper      Bronze    

- Next enter the thickness of the base material to be welded

Select a thickness from this dropdown list Select 0.001" 0.005" 0.010" 0.050" 0.100" 0.125" (1/8") 0.1875" (3/16") 0.200"   

or Enter Thickness (i.e. 0.001") (then press the Tab key)

This will give us our "Starting Estimate" amps.

- Please specify if you are doing an inside fillet weld or an outside fillet weld

- Now, check your figures and options - then press the 'Calculate' button.

Dial Current (in Amps) =

Note: Calculated Dial Current is 10% more than the minimum current needed for the weld. This allows us some headroom when using the foot pedal.
