Qualified welding instructor required.

The Welding Honor is perhaps of all the AY honors, the one with the greatest potential to cause injury. If done wrong you can also create unsafe equipment (see requirement note at end) Do not attempt to teach yourself how to weld. An experienced instructor is absolutely required for this honor.
