1.Current Control - This knob is used to set the welding current from 5 to 315 amps. Read the complete Operating Instructions section for more information on Local and Remote setting of cur- rent.

2.AC Wave Balance Control - This knob is active in the AC TIG mode only. It is used to set the amount of cleaning and/or penetration produced during an AC TIG weld. Auto Balance™ automatically sets the AC Wave balance according to the welding cur- rent. If manual adjustment is desired, the balance can be adjusted from +0 (maximum cleaning) to +10 (maximum penetration). Read the Advanced Features section for a complete expla- nation of the AC Wave Balance.

3.Post Flow Time Control - This knob is active in the TIG mode only. It adjusts the post flow time from 5 to 50 seconds for shielding gas. It also adjusts cooling water flow when the optional K1621-1 Water Solenoid Kit is used.

4.Down Slope Time Control - This knob is active in 4-Step TIG mode only. It adjusts the time (from 0.5 to 10 seconds) the welding output takes to ramp down from the preset level to 25% of that level.

5.2-Step/4-Step TIG/Stick Mode Control Switch - This switch selects the welding mode desired: TIG 2-Step, TIG 4-Step, or Stick. Read the complete Operating Instructions section for more information on TIG 2-Step and TIG 4-Step.

6.Trimmer Potentiometers - Allows the meters to be calibrated in the field.

7.Digital Ammeter - The ammeter displays actual welding current during a weld cycle and displays the peak current for approximately 5 seconds after welding is complete. Read the complete Operating Instructions section for more information on the Ammeter.
