- Large quiet muffler - Reduces noise / isolated from the engine to reduce vibration.
- Large fuel tank capacity - For long running times.
- Fuel Meter - Displays gas level in tank.
- Oil alert - Automatically shuts unit down when the oil drops below a safe operating level to prevent engine damage.
- Circuit Breakers - Automatically switches off if there is a short circuit or significant overload.
- DC Terminals - The DC terminals may ONLY be used for charging 12 volt automotive type batteries.
- DC Circuit Protector - The DC circuit protector automatically shuts off the DC
- Automatic Voltage Regulator (AVR) - An electronic device that ensures constant voltage output regardless of rated load for current sensitive devices. (i.e. computers)
- 2-wheel transport kit - For easy maneuvering

Welding Duty Cycle
The duty cycle is the percentage of time that the welder can be operated in a given 10 minute period.

For example, at a rated output of 130 amperes, the EW171's duty cycle is 50%. This means that at 130 amperes, welding can be performed for a total of 5 minutes out of every 10 minute period. The duty cycle is longer at lower operating currents, and shorter at higher currents.
