TIG WELDING SEQUENCE OF OPERATION (2-Step TIG Mode)

1.Connect an Arc Start Switch or an Amptrol to the Remote Amphenol.

2.Turn the welder, gas supply and water supply (if equipped), on. The digital ammeter/voltmeter dis- plays will illuminate when the power is on.

3.Select the 2-Step TIG Mode with the 2-Step/4-Step TIG/Stick switch.

4.Set the maximum output current using the output control knob.

5.Select AC or DC- electrode polarity. See Table B.2.

TABLE B.2

RECOMMENDED POLARITY

SETTINGS FOR TIG WELDING


	Electrode
Type of Welding	Polarity


Stainless Steel	DC-

Aluminum & Magnesium	AC

Other Metals	DC-

6.If welding with AC polarity, set the AC Wave Balance Knob to Auto Balance™. This gives the optimum ratio between cleaning and penetration, automatically adjusted of the AC Wave Balance is desired, adjust the wave balance to the desired settings. See the Advanced Features section for more information on setting and using the AC Wave Balance.

7.Set the post flow time with the post flow knob. Post flow control knob adjusts the time that the shielding gas flows (and cooling water flow, if the optional water solenoid is used) after the weld cycle. Use short post flow times with low currents and small tungstens, use long post flow times at high output currents with large tungstens.

8.Press and release the Arc Start Switch, and set the gas flow meter. The welder is now ready for weld- ing.

9.Position the tungsten electrode at the start of the weld at a 65° to 75° angle with the horizontal so that the electrode is approximately 1/8” (4 mm) above the work piece. Press the Arc Start Switch. This opens the gas (and optional water solenoid) valves to automatically purge air from the hose and torch. After a 0.5 second preflow time, the high fre- quency becomes available to strike the arc.

10.Hold the Arc Start Switch or Amptrol down until an arc is established. If using an Amptrol, read the Section on Hand and Foot Amptrol Operation. Release the Arc Start Switch or Amptrol to stop the arc and start the Post Flow timer. After the Post Flow time has expired, the gas and (optional water solenoid) valves will close. To make another weld, repeats steps 9 and 10.

TIG WELDING SEQUENCE OF OPERATION (4-Step TIG Mode)

1.Connect an Arc Start Switch to the Remote Amphenol.

2.Turn the welder, gas supply and water supply (if so equipped), on. The digital ammeter/voltmeter dis- play will illuminate when the power is on.

3.Select the 4-Step TIG Mode with the 2-Step/4-Step TIG/Stick switch.

4.Set the maximum output current using the output control knob.

5.Select AC or DC- electrode polarity. See Table B.2.

6.If welding with AC polarity, set the AC Wave Balance Knob to Auto Balance™. This gives the optimum ratio between cleaning and penetration, automatically adjusted for the output current. If manual adjustment of the AC Wave Balance is desired, adjust the wave balance to the desired settings. See the Advanced Features section for more information on setting and using the AC Wave Balance.

7.Set the Post Flow time with the Post Flow knob. Post Flow time provides shielding gas flow (and cooling water, if used) after the weld. Use short Post Flow times with low currents and small tung- stens and long Post flow times at high output cur- rents and large tungstens.

8.Set the Downslope Time with the Downslope Time Knob. This will adjust the time of the crater fill peri- od.

9.Press and release the Arc Start Switch, to set the gas flow meter if necessary. The welder is now ready for welding.

10.Position the tungsten electrode at the start of the weld at a 65° to 75° angle with the horizontal so that the electrode is approximately 1/8” (4 mm) above the work piece. Press the Arc Start Switch. This opens the gas and water valves to automati- cally purge air from the hose and torch. After a 0.5 second preflow time, the high frequency becomes available to strike the arc.
