Miller Bobcat 265 Gas or LP Engine-Driven Welder

An engine-driven welder and generator for field maintenance

The Miller Bobcat 265 is a gas or LP engine-driven welder and generator for maintenance, repair, construction, farm and work-truck use. It delivers 265 A at 27 V at 100 % duty cycle for stick and DC TIG, and constant-voltage output of 14 to 30 V for MIG and flux-cored welding with a wire feeder. Air carbon arc gouging with 3/16 in carbons is listed, and air plasma cutting is possible with optional Spectrum plasma cutters powered from the machine.

The same machine supplies 11,000 W of peak and 9,500 W of continuous auxiliary power, with weld and auxiliary power independent, so tools can run while welding. Miller describes it as over 100 lb lighter and 13 percent smaller than the previous model. An LCD interface offers Auto-Set predefined weld settings, predictive maintenance information and productivity screens, and a 10-pin connection supports Spoolmate and Spoolmatic spool guns without an adapter.

Technical specifications

Which Bobcat 265 package to choose

The spec sheet notes that ArcReach is not available on the battery charge/crank assist model, that LP output is derated by up to five percent, and that remote start/stop applies to the Rehlko gas model. The Bobcat 230 is the smaller option in the same family, rated 20 to 230 A, if stick and flux-cored work is all that is needed.

What to confirm before ordering

Decide the fuel (gasoline or LP) and the engine brand, then the options: ArcReach remote control, battery charge/crank assist, electric fuel pump for work above 5,000 ft, and running gear or a protective cage for site moves. State the processes, electrode or wire type and the auxiliary loads so the 9,500 W continuous rating can be checked. The spec sheet lists dimensions and a mounting pattern for truck installation.

How the Miller Bobcat 265 works

The Bobcat 265 has a gas or LP engine that turns a generator. The generator makes the welding current, and a separate winding supplies single-phase auxiliary power at 120 and 240 V. The welding output is direct current of 20 to 265 A for stick and TIG, or constant voltage of 14 to 30 V for MIG and flux-cored work with a wire feeder. Weld power and auxiliary power are independent, so a tool can run while the operator welds.

Installation, commissioning and maintenance notes

Run the welder outdoors or where the exhaust leaves the area, and keep it level. Check the oil and fuel before each shift and use the fuel the engine needs. Connect the work and electrode leads, set the process on the LCD and use the Auto-Set function for a first setting. Service the engine as its maker requires and keep the air filter clean.
