770088 - Hobart Flat Soapstone Refills - 7 Pack

Precision Marking for Professional Fabrication

The Hobart Flat Soapstone Refills (SKU: 770088) are an essential consumable for professional metalworkers and fabricators who demand accuracy and reliability in their layout work. Manufactured from pure, natural mined soapstone, these refills are specifically selected for their uniform texture and ability to produce clear, distinct white markings on a variety of metal surfaces. Whether you are working with mild steel, dark iron, or other industrial alloys, these soapstone markers provide the high contrast necessary for precise cutting, grinding, and welding operations.

One of the critical requirements for welding consumables is the ability to withstand extreme thermal cycling. Hobart's natural soapstone is inherently heat-resistant, ensuring that your layout lines do not burn off, fade, or discolor when exposed to the intense heat of an arc or an oxy-fuel flame. This permanence during the process—combined with easy removal afterward—makes soapstone the preferred choice for structural steel fabrication and pipe welding where weld contamination must be avoided. Unlike paint markers or wax crayons, natural soapstone does not introduce foreign chemicals into the weld pool, preserving the integrity of your work.

This package contains seven (7) flat refills, measuring standard dimensions of 3/16 inch by 1/2 inch. This specific flat profile is designed to fit securely into standard flat soapstone holders, allowing for adjustable length and protection against breakage. The flat shape also serves a practical safety and convenience function: unlike round markers, these flat stones will not roll off inclined worktables or vibrating machinery. For industrial MRO environments where efficiency is key, having a reliable stock of high-quality marking stones ensures that workflow is never interrupted by the lack of basic layout tools.

Key Technical Benefits:

• Natural Composition: Mined stone offers consistent hardness and markability.
• Thermal Stability: Remains visible near the heat affected zone (HAZ).
• Standard Fit: Compatible with most industry-standard flat holders.
• Non-Contaminating: Safe for use on surfaces prior to welding.
