Selector Switches

1. ON/OFF
Turns the machine on or off. (Located on the back of the TIG225X.)

2. TIG / MMA Selector
Switch between TIG welding and Stick (MMA) welding.

• TIG position → TIG welding mode.

• MMA position → DC Stick welding mode.

3. AC / DC Selector
Choose AC or DC current when in TIG mode.

• AC position → For aluminum and magnesium (removes oxidation).

• DC position → For steel, stainless, and most other metals.

4. 2T / 4T Torch Mode
Controls how the torch trigger behaves:

• 2T Mode → Press and hold to weld, release to stop.

• 4T Mode → Four-step process for long welds:

  1. Press to start current

  2. Release to weld

  3. Press to start downslope

  4. Release to stop welding

5. Pulse Mode (OFF / LOW / HIGH)
Controls pulsed TIG welding frequency:

• OFF → Standard (non-pulse) TIG welding.

• LOW → 0.5–10 Hz pulse frequency.

• HIGH → 10–200 Hz pulse frequency.

6. Water Cooler Power Outlet
110/220V outlet for an optional dual-voltage water cooler (max 4A).

• Matches the welder’s input power (110V input → 110V output; 220V input → 220V output).

• ⚠️ Do not power other devices with this outlet.

• If using a single-voltage cooler, unplug it when running on a mismatched input voltage to avoid damage.

Control Dials

A. Welding Current
Sets the main welding current (amperage).

• Range: 10–225A (220V) / 10–140A (110V)

B. Pre-Flow
Controls shielding gas flow before the arc starts, protecting the tungsten and weld start.

• Range: 0.1–3 seconds

C. Start Current
Initial current when striking the arc.

• Higher → easier arc start

• Lower → prevents burning thin sheet metal

• Range: 10–225A (220V) / 10–140A (110V)

D. Up Slope
Controls how quickly current rises from start current to main welding current.

• Range: 0–10 seconds

E. Base Current
Background current level during pulse welding, expressed as a % of peak current.

• Example: Peak at 100A, base at 20% → output cycles between 100A and 20A.

• Range: 5–95%

F. Pulses Per Second (Hz)
Sets how often current switches between peak and base levels in Pulse mode.

• Range: 0.5–10 Hz (Low) / 10–200 Hz (High)

G. Pulse Duty (Balance of Peak vs Base Current)
Controls penetration depth and heat input.

• Higher duty → deeper penetration, more heat

• Lower duty → less heat, safer for thin material

• Range: 10–90%

H. Down Slope
Controls how quickly current drops from welding current to end current.

• Range: 0–25 seconds

I. End Current
Current at the end of the weld, allowing crater fill before arc extinguishes.

• Range: 10–225A (220V) / 10–140A (110V)

J. Post Flow
Controls shielding gas flow after the arc stops, protecting weld and tungsten while cooling.

• Range: 0–15 seconds

K. AC Frequency
Adjusts arc cone width and stability in AC TIG mode.

• Range: 40–200 Hz

L. AC Balance
Controls the balance between cleaning (positive half) and penetration (negative half) when welding aluminum or magnesium.
