Background and Identification

The Lincoln Electric Welder Bulldog 550 model 550 K2708-2 is a gasoline-powered alternating-current stick welder and 5.5-kiloWatt peak generator. This welder/generator works for powering grinders, work lights, pumps, and emergency power. The 5500-Watt Surge AC Generator can be used for portable AC stick welding and AC generator power.

This Arc/Stick Welder includes low-grab bars that provide protection to the unit and additional leverage for lifting the machine on and off of truck beds. It provides up to 140 Amps of AC output for various applications. Users can stick weld with up to a 1/8 inch stick electrode with the welder’s 60% duty cycle. (Duty cycle is the amount of time a welder may be operated as a given output without exceeding the temperature limits of the machine’s components. Duty cycle is measured using a 10-minute cycle). Because this welder is gasoline-powered, it requires no input power. It outputs between 140 and 70 Amps with a material application thickness of 0.15 inches.

The Lincoln Electric Welder Bulldog 550 model 550 K2708-2 can be identified by its model number, which is printed on a sticker either on the top or the back of the welder. The welder includes a black frame with low-grab bars and a red engine cover with the name “Bulldog” printed on the side in white capital letters. The name “Lincoln Electric” is printed in capital letters on the side of the welder.
