SMAW
THE CIRCUIT BREAKER SUPPLYING ELECTRICITY TO YOUR WELDING SHOULD BE SHOT OFF
before disconnecting the welding machine
THE CAPACITY OF AN ARC WELDING MACHINE IS DETERMINED BY ITS RATED AMPERAGE AND
DUTY CYCLE
CHIPPING SLAG AND OTHER COATING FROM FINISHED WELDS REQUIRES
EYE PROTECTION, INCLUDING GOGGLES OR FACE SHIELDS
SMAW POWER SUPPLIES ARE DESIGNED TO PRODUCE AN OUTPUT CURRENT THAT
IS NEARLY CONSTANT
THE CIRCUIT BREAKER SUPPLYING ELECTRICITY TO YOUR WELDING MACHINE SHOULD BE SHUT OFF
before disconnecting the welding machine
YOU SHOULD INSPECT YOUR FALL PROTECTION EQUIPMENT
BEFORE EACH USE
A DINSE STYLE CONNECTOR IS
A QUICK-DISCONNECT STYLE FOR WELDING LEADS
WELD SLAG CHIPPERS AND NEEDLE SCALERS ARE TYPICALLY
PNEUMATICALLY POWERED TOOLS
A STEP DOWN TRANSFORMER CONVERTS
A HIGHER VOLTAGE TO A LOWER VOLTAGE
WELDING MACHING CAN ALSO BE POWER BY
GASOLINE OR DIESEL
SMAW POWER SUPPLIES ARE DESIGNED TO PRODUCE AN OUTPUT CURRENT THAT
IS NEARLY CONSTANT
WHEN SELECTING A WORKPIECE CLAMP, BE SURE THAT IT IS RATED
AT LEAST AS HIGH AS THE RATED CAPACITY OF THE WELDING MACHING
THE PREVENTIVE MAINTENANCE SCHEDULE FOR AN ENGINE -DRIVEN WELDING MACHINE IS USUALLY BASED ON
THE NUMBER OF HOURS THE THE ENGINE OPERATES
CHIPPING SLAG AND OTHER COATINGS FROM FINISHED WELDS REQUIRES
EYE PROTECTION
THE DUTY CYCLE OF A WELDING MACHINE IS BASED ON A
TEN -MINUTE PERIOD OF TIME
MOST ENGINE-POWER WELDING MACHINES TURN A GENERATOR THAT PRODUCES
DC CURRENT
TRANSFORMERS, TRASFORMER-RECTIFIERS, AND ELECTRIC MOTOR-GENERATORS ALL REQUIRE
ELECTRICAL POWER FROM COMMERCIAL POWER LINES TO OPERATE
A TRANSFORMER WELDER HAS AN
ON/OFF SWITCH, AN AMPERAGE CONTROL, AND TERMINALS FOR CONNECTING THE ELECTRODE
A DENSE-STYLE CONNECTOR IS
A QUICK DISCONECT
MACHINE REQUING SINGLE-PHASE POWER WILL HAVE A
THREE-PRONG PLUG
A STEP DOWN TRANSFORMER CONVERTS
A HIGHERE VOLTAGE TO A LOWER VOLTAGE
A RECTIFIER IS A DIVICE THAT CONVERTS
AC CURRENT TO DC CURRENT
SMAW WELDING MACHINES ARE CLASSIFIED BY THE TYPE OF WELDING CURRENT THEY PRODUCE
AC,DC, AC/DC
WHEN SELECTING A WORKPIECE CLAMP, BE SURE THAT IT IS RATED
AT LEAST AS HIGH AS THE RATED CAPICITY
THE BEST TIME TO CHECK ENGINE COOLANT IS
BEFORE THE ENGINE HAS BEEN USED
