OVERVIEW

Reliability for Your Robotic Cell

Keep your automation running smoothly with the Magnum PRO Robotic 550 Welding Gun. Designed for welders and fabricators who demand uptime, this thru-arm torch takes the headache out of robotic maintenance. The air-cooled design handles a massive 550 amps, giving you the power needed for heavy structural welds without the complexity of water coolers and hoses. The 'Ready-Pak' means you get everything you need out of the box, including the liner, diffuser, nozzle, and contact tip.

One of the biggest frustrations in robotic welding is maintaining the Tool Center Point (TCP) when changing parts. The Magnum PRO 550 solves this with a unified geometry that lets you switch between standard and heavy-duty consumables (350A to 550A) without having to touch the robot's teach pendant. This means faster changeovers and more arc-on time. The Copper Plus® contact tips used in this system utilize a larger mass and diameter to dissipate heat better, lasting longer than standard tips and preventing wire burn-back.

The build quality is tough enough for the harshest shop environments. The cable assembly is reinforced to handle the constant twisting and turning of a 6-axis robot, lasting twice as long as standard cables in durability tests. With the HexConnect™ bushing, you get a solid, vibration-resistant power connection that keeps the arc stable. Whether you are welding automotive parts or heavy machinery, this gun provides the consistency and access you need to get the job done right.

FAQ

The Magnum PRO Robotic 550 is rated for 550 Amps.

This model (K3359-1520ID) is an air-cooled welding gun.

Thru-Arm means the cable assembly runs through the hollow center of the robot's arm, reducing cable interference and wear.

No, the Single Tool Center Point (TCP) feature allows you to switch between 350A and 550A expendables without altering the TCP.

It includes a Contact Tip (KP2745-040), Gas Nozzle (KP2743-1-62R), Diffuser (KP2747-1), Insulator (KP2773-1), Liner (KP45-3545-6), and Gun Tube (KP3355-45).

The HexConnect bushing provides full-face electrical contact, improving conductivity and durability compared to rotating connections.

Yes, the Magnum PRO series uses a simplified selection of expendable parts that are interchangeable across semi-automatic and robotic models.
