SMAW

For proper eye protection when arc welding the minimum shade number of the filter lens should be

• 4

• 6

• 10

• 12

The amperage setting should be set while the welding machine is

• running a bead
• not under load
• warmed up
• turned off

When working in an area with other people, what should be done before an arc is struck?

• Check the electrode holder
• Tell others you plan to strike an arc
• Check the cables for cuts and burned insulation
• All of these

do you always wear ear protection when welding 

• yes
• no

What is arc blow?

• a concentration of magnetic fields in the corners and deep grooves while welding.

• a concentration of magnetic fields in the corners and deep grooves while oxyfuel cutting.

• when the arc blows through your plate

• when you strike an arc

What are some adjustments you can make when arc blow is a occurs?

• change the position of the workpeice clamp, shorten the arc length.

• change the amperage

• adjust the voltage

• none of the above

What is the ideal arc length?

• the same as the diameter of the electrode

• 3 times the diameter of the electrode

• 1/8

• 3/32

What is the easiest method for striking an arc?

• tapping

• scratching

• top

• bottom

What should your drag angle be while welding in the 1f position?

• 10-15

• 15-20

• 20-25

• 30-40

For an E-7018 electrode the 70 stands for the?

• tensile strength times 1,000 lbs
