volts? - correct-answer-15-48 V
To perform short circuit metal transfer when GMAW welding a voltage range of
what required? - correct-answer-15-22 V
What type of metal transfer when GMAW welding requires higher current
voltages? - correct-answer-Spray transfer
Insufficient current transfer between power source and filler wire is a direct result
of what when GMAW welding? - correct-answer-A badly worn contact tip on
welding gun
What part of the MIG welding gun is the contact tip fastened to? - correct-
answer-Tip adapter (gas diffuser)
, 2|Page
When GMAW welding, the travel angle of the welding gun varies from _____ to
_____ and should never exceed _____. - correct-answer-Varies from 5-15 degrees.
Shouldn't exceed 20 degrees.
What does the contact tip adapter or (gas diffuser) on a MIG welding gun do? -
correct-answer-Relays electricity to contact tip and diffuses gas flow to weld
puddle
What does the gas nozzle on a MIG welding gun do? - correct-answer-Directs gas
flow from gas diffuser to weld puddle and prevent contact tip from arcing out on
the work piece
When MIG welding, the flow meter on your botle gauge should be set at
approximately _____ to _____ cubic feet per hour. - correct-answer-20 to 25 cubic
feet per hour.
Maximum flow 35 cubic feet per hour, but can cause turbulence.
Spatter buildup on the gas nozzle and wind or drafts in the shop have a direct
effect on what? - correct-answer-Shielding gas flow and turbulence. NOTE: may
cause porosity in your weld
