Why AC/DC TIG Technology Changes Everything
AC TIG — Professional Aluminium Welding Capability
Aluminium fabrication requires more than standard TIG output.
The natural oxide layer on aluminium has a significantly higher melting point than the parent metal itself, making conventional DC TIG welding ineffective for achieving proper fusion.
The AC TIG mode on the TIG-315 solves this through controlled alternating current polarity reversal.
During the electrode-positive cycle:
✔ Oxide layer disruption occurs
✔ Surface contamination breakdown improves
✔ Cathodic cleaning action restores weldability
✔ Arc cleaning improves puddle stability
✔ Clean aluminium fusion becomes achievable
Result:
Cleaner weld beads + improved penetration + reduced contamination + superior aluminium weld integrity
This makes the TIG-315 ideal for:
- Aluminium fabrication
- Aluminium tank welding
- Aluminium frame manufacturing
- Marine aluminium structures
- Automotive aluminium fabrication
- Heat exchanger manufacturing
DC TIG — Precision Metallurgical Control
For stainless steel, carbon steel, titanium, copper, and alloy fabrication, the machine delivers highly stable DC TIG arc performance with focused heat input and superior puddle precision.
The integrated Pulse TIG functionality enables alternating peak and background current modulation, allowing:
- Reduced thermal distortion
- Controlled heat input
- Improved thin material weldability
- Better root pass consistency
- Superior cosmetic weld appearance
- Improved metallurgical control
This is essential for code-quality fabrication work.
