10231033 - ESAB Tweco Spray Master 250 MIG Gun - 15ft Miller Connection

Heavy-Duty ESAB Spray Master 250 MIG Gun

The ESAB Spray Master 250A MIG Gun (SKU: 10231033) is a legendary air-cooled torch designed for professional welders who demand reliability and comfort. Formerly known under the Tweco brand, the Spray Master series maintains its reputation for staying cool under pressure. This specific model features a Miller-style rear connection, making it a direct plug-and-play replacement for many Miller MIG welding machines.

With a 250 Amp rating at 80% duty cycle (using CO2), this gun is built to handle medium to heavy fabrication tasks without overheating. The 15-foot cable assembly provides ample reach, allowing welders to move freely around large workpieces. The gun is engineered with a unique conductor tube that rotates 360 degrees, offering flexibility in difficult-to-reach welding positions.

Maintenance is straightforward thanks to the use of standard Tweco consumables, including 11-series contact tips and 52-series gas diffusers. The simplified design means fewer parts to stock and easier troubleshooting on the shop floor. Whether you are welding mild steel, stainless, or aluminum (with the correct liner), the Spray Master 250 delivers a stable arc and consistent wire feeding.

Key Benefits

• High Duty Cycle: 80% at 250A ensures you can weld longer without stopping.
