10 Questions
What does welding amperage refer to in a welding circuit?
The amount and speed of electricity flowing in a circuit
How does welding amperage affect weld penetration?
Higher amperage settings yield greater joint penetration
How does increasing the welding voltage affect stick-out and amperage?
Increasing the welding voltage decreases stick-out and increases amperage.
What happens to welding amperage when the wire feed speed (WFS) decreases?
Welding amperage decreases
What effect does a higher wire feed speed (WFS) have on welding transfer modes?
Higher WFS shifts the process into a spray transfer mode with small droplets of wire transfer.
Which welding variable has an inverse relationship with contact-tip-to-work distance (CTWD)?
Welding amperage
What does a low wire feed speed (WFS) and voltage keep the welding process in?
Short-circuit mode
What is meant by contact-tip-to-work distance (CTWD) in welding?
The distance from the end of the contact tip to the base material
How does too high of an amperage affect welding with metal-cored wire?
Results in a dull, flaky weld
What is the relationship between welding voltage and arc length?
Higher welding voltage equals a longer arc length
