Set up and use shielded metal arc welding (SMAW)

How is the output of a SMAW machine stated?

• amperage

• resistance

• ohms

• voltage

When setting up a SMAW welding machine, what two factors determine the amperage setting?

• electrode length and polarity

• thickness of the metal and any electrode size

• polarity and arc length

• type of machine and length of weld

What is the polarity when the electrode is POSITIVE?

• balanced

• straight

• reverse

• foward

What determines the size of an arc welding machine ?
