The Tweco® Spray Master® Series 450 A MIG Gun is a high-quality tool designed for professional welders. It features a heavy-duty contact tip that can accommodate wires ranging from 0.045 to 1/16 inch in size. The ergonomic handle design reduces fatigue, allowing for comfortable extended use.
This air-cooled MIG gun is ideal for both spray and pulse welding applications. It has a simplified direct rear plug for easy installation, making it convenient to use. The 20-foot power cable offers excellent wire feedability and features a Miller® style rear connection.
With an 80% duty cycle and compatibility with argon/CO2 gases, this MIG gun can perform under pressure. It is also easy to repair and requires minimal maintenance. The gun features a diffuser that enhances performance in high heat applications. Its thick-walled, three-layer conductor tube provides higher electrical conductivity, acts as a heat sink, and ensures durability.
The heavy-duty thick-walled contact tip and diffuser increase tip life and reduce downtime with tip changes. The gun is balanced 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 prevent wire feed issues, the gun has a steel spring strain relief that provides support to the Cablehoz® coming out of the rear of the handle. Additionally, there is an optional mechanical locking trigger available, identified with the "LC" Part No. suffix. The front and rear spring strain relief and cable support ensure stability during use.
The compact, ergonomic handle design enhances comfort and maneuverability. The durable metal jacketed conductor tube ensures longevity. The gun features patented, extended-life consumables. It is also field repairable thanks to a split-half handle case that provides easy access for repairs. The mechanical cable connections for Cablehoz® spare trigger leads in Cablehoz® can also be repaired in the field.
This MIG gun offers lower heat in the handle and conductor tube thanks to the heavy wall conductor tube and front Cablehoz® connection. This construction improves electrical conductivity and reduces heat in the front end. The heavy-duty contact tip and diffuser further enhance performance in high heat applications.
For versatile use, the gun offers standard trigger on/off operation, with optional dual schedule and locking trigger configurations available. It is suitable for a wide range of welding applications, including spray transfer mode and pulse welding with straight CO2 or mixed gases.
Finally, this MIG gun offers cost-saving benefits by allowing for interchangeable front end consumables between Tweco® classic no. Series and Tweco® spray master series, reducing inventory carrying costs.
