90-Degree Heavy-Duty Cutting Attachment

The Miller-Smith MC509 is a nickel-plated steel cutting attachment built for heavy-duty welding and cutting tasks. Its 90-degree head angle suits operators who need precise torch positioning in confined workspaces. The unit pairs with WH100 torch handles and accepts MC-series tips for standard fuel-gas service.

WH100 Handle and MC-Series Tip Compatibility

Bundled compatibility with the WH100 torch handle and MC-series tips means the attachment fits directly into existing Miller-Smith torch systems without extra adapters. This integration reduces setup time and lets welders switch between cutting and welding tips using the same handle assembly.

Cuts Up to 6 Inches and Welds Up to 1/2 Inch

The attachment comfortably handles cutting thicknesses up to 6 inches and welding up to 1/2 inch, covering most medium fabrication jobs. Its 11 1/4-inch length provides reach without excessive leverage, though very thick plate or high-volume production may exceed its practical duty cycle.

Questions about this item

How often will the MC Series cutting tips need replacement during heavy use?

The MC Series tips are consumable parts; replacement frequency depends on material thickness and fuel-gas choice, so keep spares on hand for continuous cutting up to 6 in.

What limits continuous cutting depth on this attachment?

The head is rated to cut up to 6 in thick material; exceeding that depth will stall the cut and overheat the tip.

How hot does the 90-degree head get during all-day cutting?

The nickel-plated steel head absorbs intense radiant heat when cutting at full 6 in capacity; expect it to become too hot to touch without gloves.
