Other machine settings?
- Set the large Output Control knob to desired setting. The foot pedal will control the actually amperage output to the maximum set on the dial. If you need less heat, back off on the foot pedal. If you need more heat, press the foot pedal further down.
- Flipper switches, set: Remote Control , Soft Start Operative / Inop (per users discretion), Inert Gas Arc Welding, High Frequency Starting Continuous (per users discretion).
- There are two small black dials on the right hand side of the machine, These are for the high frequency start circuit. Normally both of these knobs are set such that the white indicator line on the knob is vertical.
Getting ready to weld.
- Prepare all of your materials. Ensure you have clean metal, including stainless steel wire brush on all aluminum to remove the surface coat of aluminum oxide.
- As a general rule, set tungsten extension “stick out” distance equal to the diameter of the electrode. You may have to extend it further to reach some welds as required, but note this makes it harder to ensure inert gas coverage, etc.
- As a rule of thumb, while TIG welding, arc length (the distance between the end of the electrode and the work piece) is: One electrode diameter for A/C TIG welding, and usually considerably less for D/C TIG welding. Be careful to not allow the hot electrode to contact the weld puddle, or the filler rod. If you do touch, you will see a flash of light, and molten material will wick up and contaminate the tungsten electrode. When that happens, you should stop, regrind the electrode.
