Welding 101

What is the primary advantage of AC/DC welding machines over others?

• They are less expensive.

• They are more portable.

• They offer additional features like hot start and dig.

• They require less maintenance.

What does the first two digits in the four-digit numbering system of steel rods indicate?

• The rod's length in inches.

• The flux composition.

• The welding positions.

• The tensile strength in psi.

What does a '1' in the third position of the rod's numbering system signify?

• It's suitable for all welding positions.

• It indicates a high tensile strength.

• It can only be used in flat positions.

• It's designed for overhead welding only.

What purpose does the flux serve in stick welding?

• It increases the tensile strength of the weld.

• It enhances the electrical conductivity.

• It cleans the metal surface being welded.

• It protects the weld as it solidifies.

Which rod size is not commonly used according to the video?

• 5/32 inch

• 3/32 inch

• 1/16 inch

• 1/8 inch

What is the recommended polarity setting for most welding tasks?

• AC

• DCEN

• DCEP

• Variable polarity

What is a common challenge when starting to stick weld?

• Striking an arc consistently.

• Choosing the right welding machine.

• Maintaining the weld pool.

• Selecting the appropriate rod size.

What is the correct approach to setting the welding machine's amperage?

• Set it to the maximum for all rod sizes.

• Adjust according to the thickness of the material.

• Keep it constant for consistency.

• Set it to the minimum to prevent overheating.

How can you improve the stability of your hand when welding?

• Apply more pressure on the rod.

• Use a shorter rod for tacking.

• Increase the welding machine's amperage.

• Weld in a vertical position.

Why is it recommended to practice welding on scrap metal?

• To save on material costs.

• To experiment with welding positions.

• To improve striking an arc.

• To test different rod sizes.
