About: Autodesk Technology Center San Francisco is a hub for research, development, and demonstration of new manufacturing technologies and workflows relating to configurable microfactories.

The welder will need to be set up differently each time you transition from steel to aluminum welding, and vice versa.

Step 1: Settings for Welding Steel

  • Turn the machine on with the switch on the rear panel.
  • To change the settings:
    • Push the buttons on the bottom row.
    • A green LED will indicate the selected option.
    • Some options require turning the amperage knob, and reading the result in the display.

  1. Set polarity to DC.
  2. Set process control to TIG HF Impulse.
  3. Set output to RMT STD to enable the foot pedal.
  4. Set the GAS/DIG to Pre Flow
    • Rotate the amperage knob to select .02 seconds.
  5. Set the GAS/DIG to Post Flow
    • Rotate the amperage knob to select Auto.
  6. Press the “A” button and turn the amperage knob to set the maximum amperage you plan to use.
    • The foot pedal is used to control the amperage between 0 and the maximum you selected.
    • Try starting with one amp for every .001” of material thickness.
    • ex. For 1/8" (0.125") material, start with 125 amps.

Step 2: Settings for Welding Aluminum

  • Use pure tungsten, with a green band on the end, or thoriated tungsten, with a red or yellow band.
  • Turn the machine on with the switch on the rear panel.
  • To change the settings:
    • Push the button on the bottom row.
    • A green LED will indicate the selected option.
    • Some options require turning the amperage knob, and reading the result in the display.

  1. Set the polarity to AC.
  2. Set the process to TIG HF Impulse.
  3. Set output to RMT STD to enable the foot pedal.
  4. Set the pulser to PPS
    • Rotate the amperage knob to set the number of pulses to 4.
  5. Set the GAS/DIG to Pre Flow
    • Rotate the amperage knob to select .2 seconds.
  6. Set the GAS/DIG to Post Flow
    • Rotate the amperage knob to select Auto.
  7. Set the AC waveshape to AC Frequency.
  8. Press the “A” button and turn the amperage knob to set the maximum amperage for the session.
    • The foot pedal is used to control the amperage between 0 and the maximum you set.
    • Start by setting one amp for every .001” of material thickness.
    • ex. For 1/8" (0.125") material, start with 125 amps.
