| A | B |
|---|
| Voltage | measurement of electrical PRESSURE |
| Amperage | measurement of electron FLOW |
| Wattage | measurement of amount of POWER in the arc |
| Arc Stabilizers | reduces RESISTANCE, easier to HOLD ARC |
| Step down transformer | takes high voltage, low amp current CHANGES TO low voltage, high amp. current |
| rectifier | used to change AC to DC |
| open circuit voltage | voltage at the ELECTRODE BEFORE striking an arc |
| operating voltage | voltage at the ARC DURING welding |
| duty cycle | PERCENTAGE of time welding machine can be used CONTINUOUSLY |
| tap type | TYPE of welding MACHINE that allows the selection of higher current settings by TAPPING into the secondary coil |
| loose connection | cause PROPERLY SIZED electrode holder to OVERHEAT |
| Maximum safe open circuit voltage | 80 volts |
| Temp of SMAW arc | 11,000 degress F, 6000 C |
| prevent bad connection | occasionally touch work clamp |
| maximum lenght of cable splice | 10 ft |
| reason for cable splice | comfort, ease of work |
