PNA Series Welding Liners are commonly used in:
Automotive workshops – ensuring smooth wire flow for body repairs and fabrication.
Heavy fabrication industries – ideal for steel structure production and large machinery welding.
Shipbuilding and offshore welding – continuous duty applications where reliability is critical.
General manufacturing and maintenance – providing consistent welds in routine industrial use.
Their key function is to reduce wire drag, prevent feeding issues, and maintain continuous arc performance, making them essential for productivity in welding operations.
PNA Series Liners are made from high-strength spring steel wire, with options available for specialized wires:
Steel liners → standard option for carbon steel and stainless steel wires.
Brass-coated liners → improved durability and reduced friction for heavy-duty use.
PTFE (Teflon) liners → recommended for aluminum and other soft wires to prevent shaving and feeding problems.
These materials are carefully chosen to balance strength, conductivity, and smoothness, ensuring maximum performance.
Optimized for PNA torches – designed to perfectly match PNA Series MIG welding systems.
Smooth wire feeding – minimizes interruptions and ensures stable weld arcs.
Durable construction – withstands continuous industrial usage.
Reduced friction – extends both liner and contact tip lifespan.
Multi-material compatibility – suitable for steel, stainless, and soft wires (aluminum with PTFE liner).
Easy to install and replace – allows quick maintenance and reduced downtime.
The PNA Series Welding Liner is engineered for long-lasting service. Its precision inner bore ensures smooth wire passage while reducing tip wear.
