9ST9078-1 - Lincoln Electric T9078-1 Sub-Arc Thumb Screw (10 Pack)

Genuine Lincoln Electric Hardware for Sub-Arc Welding

Maintain the precision and reliability of your submerged arc welding operations with the Lincoln Electric Sub-Arc Thumb Screw (Part Number T9078-1). Sold in a convenient pack of 10, these thumb screws are essential small components that play a big role in the functionality of your welding head assembly. Designed to meet the exact specifications of Lincoln Electric equipment, they ensure a perfect fit and reliable performance in demanding industrial environments.

Tool-Free Adjustments

The defining feature of the T9078-1 is its knurled head, which allows operators to tighten or loosen the screw by hand. This is particularly advantageous in a welding environment where swapping out contact tips, nozzles, or adjusting wire guides needs to happen quickly. By eliminating the need for a screwdriver or hex key for this specific adjustment, these thumb screws streamline maintenance tasks and reduce downtime between welds. The textured grip ensures you can apply sufficient torque even while wearing light work gloves.

Importance of OEM Replacements

When dealing with high-amperage processes like Submerged Arc Welding (SAW), every connection matters. Using genuine Lincoln Electric parts guarantees that the threading matches your equipment perfectly, preventing stripped threads or loose components that could lead to arcing or wire feed issues. These screws are manufactured from durable materials capable of withstanding the heat and mechanical stress associated with heavy-duty welding operations.

Stock Up for Maintenance

Small hardware items are often the first things to get lost or damaged during routine maintenance. A dropped screw in a busy workshop can be impossible to find, halting production unnecessarily. By purchasing the T9078-1 in a 10-piece pack, you ensure that your maintenance team always has spares on hand. Whether you are running a single sub-arc station or a fleet of automated welding heads, keeping a stock of these essential fasteners helps maintain continuous productivity.

Applications

These thumb screws are typically used to secure contact assemblies, wire straighteners, or nozzle components within the sub-arc welding head. They are compatible with various Lincoln Electric SAW systems. Verify your equipment's parts manual to confirm T9078-1 is the correct fastener for your specific model.
