The learner will understand and be able to apply the common welding variables of the GMAW process.
The learner will identify the advantages and disadvantages of the four modes of GMAW transfer.
In this animated and interactive object, learners follow steps that begin with choosing the correct drive roll and include feeding the electrode wire from the spool to the welding gun.
In this interactive object, learners read an explanation of the electrodes used for welding with the GMAW and FCAW processes. In two matching exercises, students test their knowledge of classification and specification numbers.
Learners view wire feed power sources ranging from 110-volt, single phase units to 460-volt, three-phase units. A description and photos of each are provided.
In this interactive object, learners follow steps to assemble a wire feed welding torch or gun.
