TIG 250P AC DC DIGITAL ZELDA

TIG 250P AC DC DIGITAL ZELDA

Description

The ZELDA TIG AC/DC 250 PULSE DIGITAL is a portable welding machine with INVERTER IGBT technology, ideal for metallurgical work, maintenance, repairs, and light industry. It features automatic adaptive arc power for stable welding without increased spatter. The HOT-START function facilitates arc ignition, while the automatic reset safety protects against voltage fluctuations and overload.

Advantages:

• Reduced heat input and increased control with DC TIG function.
• Two types of AC waveforms:
  • Square: Fast cooling and deep penetration.
  • Sinewave: Low noise and good melting.
• Three AC waveform control options:
  • Balance for oxide removal adjustment.
  • Frequency control for arc width.
  • Range control for temperature.
• MIX TIG with AC/DC current for a concentrated arc and reduced temperature.
•  PRE-FLOW and POST-FLOW gas settings.
• It features 2T and 4T options.
