The Tweco® Spray Master® Series 250 A MIG Gun is a high-quality tool designed to meet the needs of professional welders. It features a heavy-duty contact tip that can accommodate wire sizes ranging from 0.035 to 0.045 inches. The ergonomic handle design reduces fatigue, allowing for prolonged use without discomfort.
This air-cooled MIG gun is perfect for both spray and pulse welding applications. It has a simplified direct rear plug that makes installation quick and easy. The 25' cable MIG gun has a standard 60-degree conductor tube that can swivel 360 degrees around the handle. It can be rapidly replaced without removing the conduit.
With its rear Miller® connection and fully insulated Mig-Kwik connection, this MIG gun offers great flexibility. It has an 80% duty cycle when used with argon/CO2 gases and can deliver exceptional performance under pressure. Additionally, it is easy to repair and requires minimal maintenance.
The MIG gun has several features that enhance its performance. It includes a diffuser that improves its functionality in high heat applications. The thick-walled, three-layer conductor tube increases electrical conductivity and acts as a heat sink, ensuring durability.
The heavy-duty thick-walled contact tip and diffuser extend the life of the tip and reduce downtime associated with tip changes. The balanced design of the gun allows it to pivot at the center of the handle, making it easy to use in various welding positions and reducing operator fatigue. The extended trigger length keeps the hand away from the arc, minimizing radiated heat.
To ensure smooth wire feed, the MIG gun has a steel spring strain relief that supports the Cablehoz® coming out of the rear handle. It also features optional mechanical locking triggers identified with "LC" Part No. suffix. The front and rear spring strain reliefs and cable support further enhance its durability.
The compact and ergonomic handle design ensures comfortable handling during use. The durable metal jacketed conductor tube and patented extended life consumables contribute to its long-lasting performance. Additionally, it is field repairable, thanks to its split-half handle case that provides easy access for repairs. The mechanical cable connections for Cablehoz® spare trigger leads also make field repairs hassle-free.
The MIG gun is designed to operate with lower heat, thanks to its heavy-wall conductor tube and front Cablehoz® connection. This improves electrical conductivity and reduces heat in the front end. The heavy-duty contact tip and diffuser also enhance performance in high heat applications.
This MIG gun offers a range of gun configurations to suit different welding needs. It has a standard trigger on/off operation, but optional dual schedule and locking triggers are also available. Its wide welding applications include spray transfer mode and pulse welding with straight CO2 or mixed gases.
By using this MIG gun, welders can enjoy lower inventory carrying costs. The front end consumables of the Tweco® classic no. Series and Tweco® Spray Master Series are interchangeable, reducing the need for multiple sets of consumables.
In summary, the Tweco® Spray Master® Series 250 A MIG Gun is a reliable and versatile tool that meets the high standards of professional welders. Its durable construction, ergonomic design, and advanced features make it a valuable asset for any welding project.
