Closed TIG Orbital Welding Heads represent the cutting edge of welding technology advancements.
These welding heads offer high-precision, reliable welding solutions. The closed design significantly enhances performance by shielding the welding arc from external disturbances such as air drafts and contaminants. This creates an immaculate and stable welding environment, resulting in superior weld quality with minimal defects.
With orbital welding capability, these heads ensure uniform and consistent welds around pipes and tubes, providing precise control over welding parameters. This guarantees each weld's uniform strength and flawless appearance.
Structural composition: Typically includes the power supply part (encompassing transformers, rectifiers, filters), the control circuit part (facilitating arc starting, arc stabilization, wire feeding, and current regulation), the welding circuit part (such as the conductive nozzle, welding wire, circuit ground wire), and the shell part (for support and protection).
