Introduction to The Ironhorse 300S 700V DC
The Ironhorse 300 700V DC is a portable welder using an inverter type power supply to
generate the output power.
The Ironhorse 300 700V DC is primarily designed for stick welding (SMAW). It can also be used
for TIG (GTAW) welding, using the Lift Start principle, as well as arc gouging and stud welding.
Use Range I when stickwelding, when possible. The first range produces a softer arc than that
of Range 2. (See Paragraph 3.1.3)
The Ironhorse operates on DC input voltage 500V to 800V DC. The DC input voltage is
connected to a circuit breaker. The output side of the breaker is connected to a diode, which
protects the welder from being connected to the wrong polarity.The DC voltage is converted to
AC by a DC to AC 60 HZ inverter. The 480V AC is connected to an auxiliary transformer which
transforms the voltage to 48V AC for the fan motor and the control board.
