Winterize Your Gas Engine Welder Generator

Tuesday, October 15th, 2013
If you live in a colder climate and use an engine-driven welder/generator, you need to take a few precautions to make sure you properly maintain the equipment during winter months. Whether you continue using it regularly or will pack it away for the winter, take note of the following:
  • Use a lighter weight oil for temps lower than 0 degrees F.
  • Avoid phase separation (ethanol and gasoline separate causing engine seizure) by using additives and keeping the fuel tank as full as possible at all times.
  • Drain the carburetor of fuel if you expect the engine to sit unused for a long period of time.
  • Prevent carburetor icing by adding isopropyl alcohol to your fuel supply and avoid extended periods of no-load idling.
  • Keep your battery fully charged to keep it from freezing.

Maintaining your welder/generator’s gas engine

Wednesday, May 15th, 2013

A little preventative maintenance goes a long way in keeping your welder/generator in top shape. The article below walks through best practices for maintaining the gas engine in your welder/generator, and the consequences of poor maintenance. Regular maintenance will:

  • Extend engine/welder life
  • Ensure peak performance at all times
  • Maintain reliability/avoiding costly breakdowns
  • Prevent voiding warranty coverage
  • Maximize resale value

Miller Reinvents Bobcat™ Engine-Driven Welder Generators

Monday, April 9th, 2012

Miller has re-engineered its class-leading Bobcat line of engine-driven welder/generators to reduce sound, reduce weight, offer a smaller footprint, reduce fuel use and simplify daily maintenance. Sound on the newly designed Bobcat models is reduced by as much as 33 percent, and the machine is up to 5 inches shorter and 55 pounds lighter (depending on the model). The Electronic Fuel Injection (EFI) option with the Bobcat 250 also reduces fuel use by as much as 27 percent compared to carbureted models.

Engine-driven welder/generators are ideal machines for service trucks and/or emergency power situations on farms and ranches, and are also often found in construction, MRO, and fabrication applications.

The EFI option (Bobcat 250 only) optimizes the air/fuel ratio for less emissions, longer runtimes and superior performance compared to carbureted models. It provides more reliable starting performance in cold climates, requires no choke, and is less prone to fuel deterioration due to infrequent use. Payback can be achieved in a matter of months with up to 27 percent fuel savings.

Each Bobcat engine-driven welder/generator has also been fully optimized for truck integration. The shorter and lighter design allows more room for other tools and equipment, and reduces the wear and strain of a heavier machine on the truck’s chassis. Daily maintenance has also been made easier with front panel displays to help users keep track of service intervals, as well as the intuitive placement of service points. Oil and air filter checks are performed from the top by the front panel, and fuel fill and oil drain/filter are easily accessible on the side. Tool-less panels allow for quick access.

The three new models are:
