The ESAB 598786 Spring Liner is a critical maintenance component for the ST-16 MIG welding gun series. In industrial welding applications, the liner acts as the spinal cord of the MIG gun cable assembly. Its primary function is to guide the electrode wire from the wire feeder to the contact tip with minimal friction and electrical resistance. This specific liner is constructed from high-tensile spring steel, designed to withstand the rigors of shop environments where cables are frequently bent, twisted, and dragged.
Wire feeding issues are often misdiagnosed as machine or drive roll problems when the root cause is actually a compromised liner. A liner that has accumulated debris or has been mechanically deformed will increase the drag coefficient on the wire. This forces the drive motor to work harder and can cause wire slippage or deformation. The ESAB 598786 is manufactured to precise tolerances to maintain the correct inner diameter, ensuring that the wire is supported without binding, while still allowing for the necessary flexibility of the gun cable.
Regular inspection and replacement of the gun liner are standard preventive maintenance procedures recommended for all MIG operations. When installing the 598786, it is crucial to ensure the liner is cut to the correct length according to the manufacturer's specifications to prevent gaps between the liner and the gas diffuser or power pin, which can lead to gas turbulence or wire shaving accumulation. This OEM part ensures that your ST-16 torch operates within its original design parameters.
