Bulldog 5500 Welder Generator

This is an AC-only machine: a portable AC generator rated 4,000 watts continuous and 5,500 watts surge, paired with AC stick welding up to 1/8-inch electrode and no DC welding capability at all. A canvas cover ships with the unit for protection when it is not in use.

What it is built for

Because the generator section runs independently of welding, it covers grinding, work lights, pumps, motor starting, and emergency backup power alongside basic AC stick repairs, which suits a shop or ranch that needs one portable unit for several light-duty jobs rather than a dedicated welder. Low-lift grab bars are built in to give better leverage when loading it on or off a truck bed.

Specification and fit notes

• Frame is 1-1/4-inch diameter rugged tube construction for all-around protection on the job
• Rated output is up to 140 amps AC, with a duty cycle of 30 percent at 125 amps and 60 percent at 100 amps
• Shipping weight is 255 pounds, suited to beginner and weekend-warrior skill levels
• Rated single-phase, light-industrial duty; Lincoln covers this new unit for 3 years

Because there is no DC output, confirm this matches your welding needs before ordering if you expect to run DC stick, TIG, or MIG processes at any point.

Can this unit weld with DC current? No, it is AC only, with no DC welding capability.

What else can the generator power besides the welder? Lights, pumps, grinders, and motor-starting loads, per the listed generator rating.
