IGBT ADVANCED TECHNOLOGY 3 OPTIONAL WAVE PATTERN WHEN WELDING ALUMINUM
1. Sin: The standard setting for a low noise and stable arc;
2. REc: with decreased edge steepness, for reducing noise levels compared to those that occur with the 100% rectangular waveform.
3. OFF: Stable but loud arc.
FEATURES-HF ARC IGNITION MANAGEMENT SYSTEM
FEATURES
1. Excellent arc ignition has a significant impact on TIG welding.
2. If any equipment not suitable in high frequency environment, the welder can control the highfrequency of ignition to be minimum 10Hz;
3. SHELLMAX Digital Welders can adjust optimum arc ignition current with micro computer control in any tungsten electrode (for example green pure electrode) or any arc ignition way (HF ignition or LIFT).
4. SHELLMAX Digital Welders are initially designed for radiation reduction and screen increment.
