Best Practices
Neptune MIG should be used only on pre-cleaned aluminum to produce sound, porosity free welds.
Use stainless brush for cleaning.
Preheat 400ºF (204ºC) to 600ºF (315ºC) for sections over 1/4”.
We recommend Gemini Anti-Spatter spray for lasting protection of your contact tip and MIG nozzle (see chemical aids in Abrasives & Metal Working products section).
