The advanced Sifweld Evolution Aerotech range of AC/DC TIG machines have features normally only
available on high end Aerospace specific TIG welding machines, including: Four power levels of HF ignition
strength, fully adjustable cleaning and welding current levels on both the positive and negative parts of
the AC Square Wave Cycle.
A professional, microprocessor-controlled inverter welding power source for AC TIG, DC TIG & MMA
applications. The use of IGBT technology providing a compact and lightweight machine including the
advanced Aerotech features, high speed pulse and the complete range fully adjustable parameters
normally expected on a professional TIG welding machine. Multimodal for TIG HF / TIG Lift / MMA process.
Features
• PFC Technology: Power factor more than 0.99. Multiple advantages such as energy saving and welder
input voltage. Input voltage, works with single-phase: 110V/230V.
• Fully adjustable Cleaning and Welding current levels on the Negative and Positive parts of the AC
Square Wave.
• Lift TIG and HF Start Modes
• Adjustable arc force, hot start & anti stick control for greater control and ease of use when MMA welding.
• Electronic HF TIG arc ignition system for contamination free and easy arc starting with low EMF
interference.
• Four levels of High performance HF Strength for use on ultrathin surfaces with no deformation.
• High Speed Pulse
• 2T/ 4T/ Spot trigger control.
• LCD screen for accurate setting & feedback of welding output.
• Intelligent protection: Over-voltage, over-current, over-heat, when the problems listed before occurred,
the alarm indicator on the front panel will be on and the output current will be cut off. It can self-protect
and prolong the using life.
• Designed to work with diesel generators and to avoid failures due to its voltage spikes.
• Wire/Wireless Foot Pedal available.
