One of the procedures to prevent fires or explosions during A-CAC work is to make sure that _________________

• Carbon electrode to be used are completely wet

• Carbon electrode to be used are completely dry

• Are completely overheated

• Carbon electrode to be loosely

Washing is a process used to prepare the surface of the base metal by _____________

• compressed air

• removing objects & projections from the surface

• Gouging & carving objects

• removing objects & using water

The A-CAC process uses a high-current electric arc between the base metal and the end of a(n) __________

• Carbon graphite electrode to melt the base metal

• between the electrode and the base metal surface

• concentric cable system

When cutting and gouging with A-CAC equipment, the jet orifices of the torch head(s) should be located

• fire-watch in A-CAC work area

• size of the electrode

• between the electrode and the base metal surface

• between base metals

Light-duty gouging or cutting is typically done with a →

• 50cfm

• 200A welding machine

Compressed air is supplied to the torch through a hose attached to a fitting on the

• end of a nozzle

• by a welding machine

• DC voltage machine

• end of a torch cable

The most common style of A-CAC electrode used for manual cutting or gouging is the round electrode

• False

• True

Because A-CAC activities tend to blow molten metal considerable distances, it is important to station a(n)

• fire watch in the A-CAC work area

• fire alarm system

• glass window

Torches with a special washing heads in which the air jet orifices are located on only one side of the electrode are limited to cutting from

• five directions

• two directions

• one direction

• four directions
