Question

quiz
question 1 of 3
match each welding variable to the correct letter in the diagram.
contact tip-to-work distance
electrode extension
stickout
contact tip setback
standoff distance
d - wire length from electrode to tip
g - distance from nozzle to work
f - distance from end of electrode to end of nozzle
c - wire length from nozzle to wire tip
d - wire length from electrode to tip
h - distance from electrode to work

Explanation:

Identify the components in the diagram

Using the Electrode Extension and Contact Tip-to-Work Distance knowledge points, we label the physical parts of the GMAW torch shown in the diagram:

• A represents the gas nozzle.
• B represents the contact tip.
• The wire electrode extends from the contact tip B down toward the workpiece.

Define each welding variable

Using the Electrode Extension, Contact Tip-to-Work Distance, Contact Tip Setback, and Standoff Distance knowledge points:

• Contact tip-to-work distance (CTWD): The distance from the end of the contact tip to the work. In the diagram, this is represented by H.
• Electrode extension: The length of electrode extending beyond the end of the contact tip. In the diagram, this is represented by D (described as "wire length from electrode to tip" or more accurately, wire length from contact tip to wire tip).
• Stickout: The length of electrode extending beyond the end of the gas nozzle. In the diagram, this is represented by C (described as "wire length from nozzle to wire tip").
• Contact tip setback: The distance the contact tip is recessed inside the gas nozzle. In the diagram, this is represented by F (described as "distance from end of electrode to end of nozzle" where "electrode" refers to the contact tip).
• Standoff distance: The distance from the end of the gas nozzle to the workpiece. In the diagram, this is represented by G (described as "distance from nozzle to work").

Match variables to the dropdown options

We align our definitions with the visible dropdown options in the interface:

• Contact tip-to-work distance matches H - distance from electrode to work (where "electrode" refers to the contact tip).
• Electrode extension matches D - wire length from electrode to tip (where "electrode" refers to the contact tip).
• Stickout matches C - wire length from nozzle to wire tip.
• Contact tip setback matches F - distance from end of electrode to end of nozzle (where "electrode" refers to the contact tip).
• Standoff distance matches G - distance from nozzle to work.

Answer:

Welding Variable	Matching Diagram Letter & Description
Electrode extension	D - wire length from electrode to tip
Stickout	C - wire length from nozzle to wire tip
Contact tip setback	F - distance from end of electrode to end of nozzle
Standoff distance	G - distance from nozzle to work
