Flux It
This machine feeds the welding wire automatically through a gun
What is a wire feeder?
This is the type of gas FCAW-S uses.
What is No GAS?
This welding process uses a tubular wire filled with flux.
What is flux-cored arc welding?
This gas mixture is commonly used with dual-shield flux-core welding.
What is 75% argon / 25% CO₂?
This is the minimum shade we use.
What is shade 10?
This is what the E in E71T-1 represents.
What is Electrode?
This is what happens when the wire breaks and backs up into the machine.
What is Birds nest/ Rats nest?
This unwanted metal residue forms on top of flux-core welds and must be removed.
What is slag?
This is what we call the electrode extension in FCAW.
What is Stick Out?
This is the number we must NEVER go over on Acetylene.
What is 15psi?
This is the type of drive rollers used in FCAW.
What is Knurled drive rollers?
This is the polarity for Dual Shield.
What is DCEP?
The duty cycle is measured by the amount of weld time in a _____ period.
What is 10min?
This is the part of the welding gun transfers current to the wire.
What is Contact Tip?
This gas hazard is created when welding in confined spaces without proper ventilation.
What is oxygen depletion / buildup of toxic gases?
This is the polarity for FCAW-S.
What is DCEN?
This weld defect occurs when the weld metal fails to fuse properly with the base metal.
What is lack of fusion?
Filler passes are made with what kind of bead?
Filler bead/ Stringer bead
This number should be facing you when changing the drive rollers.
What is the wire diameter size? (.045 or .035)
Before making adjustments or replacing wire, you must do this to prevent accidental arc contact.
What is turn off the welder / disconnect power?
This is the power supply FCAW requires.
What is CP constant potential/ CV constant voltage?
This adjustment controls how fast the wire is fed into the weld.
What is wire feed speed?
The book states that there are 3 reasons for porosity, give me one.
Moisture in the flux
Improper gun Manipulation
Surface Contamination
This welding parameter controls the heat input and penetration of the weld.
What is voltage?
This is the organization that sets welding codes and standards in the U.S.
What is AWS?
