The ESAB 36468 is a specialized Spool Brake Assembly designed specifically for the MT-250SG Spool Gun (associated with part number 36779). This component plays a critical role in the wire feeding system of the spool gun. Its primary function is to apply controlled friction to the wire spool hub, thereby preventing the wire from coasting or unraveling—commonly known as "birdnesting"—when the welding trigger is released and the feed motor stops.
Proper tensioning of the wire spool is essential for consistent arc starting and smooth wire feeding. If the brake is worn or improperly adjusted, the spool may continue to spin due to inertia, causing loose loops of wire inside the canister. These loops can tangle, leading to feed stoppages, liner jams, and significant downtime. This assembly kit replaces the worn braking mechanism to restore factory-specification tension control.
As a genuine ESAB replacement part, this assembly ensures perfect dimensional fit and compatibility with the MT-250SG housing. It is engineered to withstand the thermal and mechanical stresses typical of industrial welding environments. Maintenance personnel should inspect the spool brake periodically for wear, particularly the friction pads or surfaces, and replace the assembly if proper tension cannot be maintained via adjustment.
