Closed TIG Orbital Welding Heads represent the pinnacle of welding technology advancements.
These welding heads offer high-precision, reliable welding solutions with their closed design providing remarkable benefits. The design shields the welding arc from external disruptions such as air drafts and contaminants, crafting a pristine and stable welding environment. This leads to superior weld quality with minimal defects.
The orbital welding capability ensures uniform and consistent welds around pipes and tubes, offering precise control over welding parameters. This guarantees uniform strength and appearance for each weld.
Structural composition: typically includes the power supply section (with transformers, rectifiers, filters, etc.), the control circuit section (for arc starting, arc stabilization, wire feeding, and current regulation), the welding circuit section (like conductive nozzle, welding wire, circuit ground wire), and the shell section (for support and protection).
