TIG 500PULSE Welding Machine

escription:

This is a professional-grade AC/DC TIG and MMA welding machine designed for precision welding of a wide range of metals including aluminum, steel, and stainless steel. With extensive control features, it supports everything from thin sheet TIG welding to heavy-duty tasks. It also includes multiple welding modes and programmable arc control for maximum flexibility.

⚙️ Welding Modes Supported:

• TIG AC/DC:

  • AC Mode: For aluminum and magnesium welding (cleans surface oxides).

  • DC Mode: For steel, stainless steel, and other metals.

• MMA (Manual Metal Arc):
  Covered electrode welding for general-purpose applications.

---

🔄 Operation Modes:

• 2T Mode (Two-Touch):
  Arc starts and stops with pressing and releasing the torch trigger — for short welds.

• 4T Mode (Four-Touch):
  Press once to start arc, release to continue welding, press again to stop — ideal for long welds.

• Special 4T Mode (S.4T):
  Advanced version of 4T allowing dynamic current adjustments during welding.

• Spot Welding Mode:
  Time-controlled spot welds for precision work on thin materials.

⚙️ Adjustable Welding Parameters:

• Pre-Gas Flow:
  Protects tungsten and weld pool by flowing shielding gas before arc ignition.

• Hot Arc Start:
  Momentary high current at arc start for improved ignition.

• Arc Start Settings:
  Adjustable arc initiation for smooth, controlled starts.

• Slope Up / Down:
  Gradual increase/decrease of current to prevent thermal shock and crater cracks.

• Welding Current (Main):
  Set desired welding amperage.

• Pulse Frequency:
  Adjust number of pulses per second — useful for thin materials.

• Spot Welding Time:
  Controls duration of spot welds precisely.

• AC Balance:
  Controls cleaning vs. penetration ratio during AC TIG welding.

• AC Amplitude & Frequency:
  Fine-tunes arc shape and penetration.

• End Arc Control & Gas Delay:
  For clean arc termination and weld pool protection after arc stops.
