TIG Welding Settings: Stainless Steel & Aluminum (Step-by-Step)

tig welding stainless steel settings
Written by Willie Osgood

There are a handful of welding methods that blacksmiths and forgers commonly use, including Tig, Mig, Oxyacetylene, and Stick. TIG stands for Tungsten Inert Gas that produces heating through an arc of electrical energy to the steel or metal surface you intend to weld. TIG welding stainless steel settings or metal welding settings consist of different configurations.

Setting up a TIG welder for stainless steel welding is a tricky process that you must know before you buy your best TIG welder. Here, we are going to explain the procedure for TIG welding settings for steel and aluminum, or more specifically,

a) Setting up the TIG welding
b) Changing settings, settings for GAS, and maximum amperage
c) Setting up the aluminum welding
d) Changing settings, settings for GAS, AC Frequency, Pulser, and maximum amperage

Stainless Steel Settings for TIG Welding

TIG Welding Setting

Every time you transit between from aluminum to steel, you need to change the setup. Follow the TIG welding settings for stainless steel below:

Step 1: Changing Settings

  • Turn on the machine and the rear panel
  • Tap the bottom row buttons
  • An LED green light will ensure you the chosen option
  • Some of the options need amperage knob and result display
  • Set the polarity settings to DC
  • Later, check the process control and set to TIG HF Impulse
  • You need to enable the foot pedal by setting the output option to RMT STD

Step 2: Setting GAS/DIG

  • To set this ,choose GAS/DIG to Post Flow
  • Twirl the amperage knob and select the option Auto
Weldpro Digital TIG 200GD ACDC 200 Amp Tig/Stick Welder with Pulse CK 17 Worldwide Superflex Torch 3 Year Warranty Dual Voltage 220V/110V welding machine
  • Weldpro's flagship 200 amp AC/DC TIG welder that goes beyond simply welding steel and aluminum. AND NOW WITH A FULL 3 YEAR WARRANTY!
  • The model 200 is also a digital designed TIG welder equipped with full function TIG welding features found on machines priced much higher.
  • Start and end amps, upslope, downslope, fully adjustable pulse, AC balance, AC frequency. 2T-4T
  • Excellent Professional design rocker style foot pedal without annoying intermediate amperage control. And now available with the optional CK Worldwide superflex cable and flex head number 17F torch with independent trigger switch.
  • Also fully capable MMA stick welding function with stinger included.

Step 3: Setting Maximum Amperage

  • Push the ‘A’ button to turn the amperage knob to maximum
  • Use the foot pedal to control the amperage from 0 to maximum numbers
  • Per 0.001 material thickness, start with one amperage number. For instance, per 1/8-inch or 0.125-inch material, you should start with 125 amps

Aluminum Settings for TIG Welding

The aluminum settings require you to use pure tungsten or thoriated tungsten with a green, red and yellow band.

Step 1: Changing Settings

  • Turn on the machine and the rear panel
  • Tap the bottom row buttons
  • An LED green light will ensure you have the chosen option
  • Some of the options need amperage knob and result display
  • Set the polarity settings to AC
  • Later, check the process control and set to TIG HF Impulse
  • You need to enable the foot pedal by setting the output option to RMT STD

Step 2: Setting Pulser

  • At first, set the pulser to PPS
  • Twirl the amperage knob and select the pulse number to 4

Step 3: Setting GAS/DIG

  • To set this , choose GAS/DIG to Pre Flow
  • Twirl the amperage knob and select the option 0.2 seconds
  • Again choose GAS/DIG to Post Flow
  • Twirl the amperage knob and choose the Auto option

Step 4: Setting AC frequency

  • Set AC waveshape option to AC frequency

Step 5: Setting Maximum Amperage

  • Push the ‘A’ button turn the amperage knob to maximum
  • Use the foot pedal to control the amperage from 0 to maximum numbers
  • Per 0.001 material thickness, start with one amperage number, for instance, per 1/8-inch or 0.125-inch material, you should start with 125 amps

To conclude, as part of knowing how to set up a tig welder, you have now surely realized that TIG welding stainless steel settings is a complicated and tricky process; just like using a MIG welder. Gas flow, arc length, and amperage are a few essential factors related to this process. Make sure these parts operate correctly for better output.
