record of each weld, so that if quality questions arise, the process of trac-
ing the root cause of a problem is greatly simplified.
Statement of purpose: This manual is intended for use in an Arc
Machines, Inc. Model 307 Tube Welder Training class taught by a factory-
approved Arc Machines, Inc. Instructor. IT IS NOT A SUBSTITUTE FOR
THAT TRAINING. The purpose of such a class is to enable welding person-
nel to quickly and easily understand the basic functions and safe operation
of the Model 307 Power Supply and appropriate weld head(s) and to use this
equipment successfully in their application.
Students must be able to correctly set up the power supply and be able to
calibrate and install the weld head with correct tube-clamp inserts and the
correct tungsten type, diameter and length. They must understand the
basics of purging and know how to set the correct flow rates for the weld
head they are using.
Hands-On. Students are given sufficient hands-on training to enable them
to generate weld programs, to make welds, and to evaluate the welds.
Trainees should also be familiar with the end-preparation requirements for
orbital welding. They are expected to recognize an acceptable weld for
their industry or application and be able to make adjustments in the weld
program or procedures in order to produce welds that comply with the
standards of their industry.
Upon successful completion of this course, which is typically comprised of
two 8-hour days and, at the discretion of the instructor, students will
be awarded an Arc Machines, Inc. Certificate of Completion.
