Heat RuleFormula
Heat entire piece — solder flows to hottest point toward flux.
Never solder with closed containers of pickle nearby.Standard
Wear didymium glasses for torch work.
Measure Twice
Verify all calculator inputs against physical measurements before cutting or mixing.
Quality Check
Compare results to known good references in soldering before final assembly.
Stop If Unsafe
Pause immediately if tools malfunction, ventilation fails, or materials react unexpectedly.
