Page 12: 230V Input
INSTALLATION 230V INPUT FIGURE A.1 The AUTOPRO™ 155S is provided with a 230V cable, 6.0ft.(1.8m) in length, with a 50 Amp (NEMA 6-50P) plug molded onto the cord. The rated output of the AUTOPRO™ 155S is available Electrode when connected to a 30A branch circuit. When con- Holder nected to a branch circuit with lower ampacity, lower welding current and duty cycle must be used.
Page 13: Operation
OPERATION WELDING CAPABILITY Read and understand this entire section before operating your machine. The AUTOPRO™ 155S is rated at 150 amps at 30% SAFETY INSTRUCTIONS duty cycle on a ten minute basis. It is capable of high- er duty cycles at lower output currents. If the duty WARNING cycle is exceeded, a thermal protector will shut off the output until the machine cools.

This normally occurs when the duty cycle FRONT CONTROL PANEL of the machine has been exceeded. Leave the (See Figure B.1) machine on to allow the internal components to 1.
Page 15: Stick-Welding Circuit
OPERATION STICK-WELDING CIRCUIT This figure closely resembles what is actually seen during welding. The “arc streamʼʼ is seen in the middle (See Figure B.3) of the figure. This is the electric arc created by the electric current flowing through the space between the FIGURE B.3 end of the electrode and the work.
