*Pickle=a liquid solution to clean metal after it has been heated.
*Annealing=a heat process used to soften work-hardened metal.
*Flux=a paste or liquid solution applied to cold metal to keep it clean while soldering.
*Solder=an alloy of silver and brass used to hold metal parts together.

Process Tips:
*Use solder in this order: 1. Hard (melts at 1475 degrees), 2. Medium (melts at 1390 degrees), 3. Easy (melts at 1325 degrees). |
*Reasons solder won't work: Not clean Poor fit Not hot enough. |
