After the reduction has been completed, the molten slag and lead are taken out of the furnace hearth at a temperature that is approximately equal to the melting point of the slag. The slag runs over the top into a granulation system and is water quenched, granulated, and discarded. Metal values in the slag include approximately 5% zinc and 0.5% ...

Pulsed MIG also enables in-the-flat, horizontal, vertical up, or overhead welding without a slag system. It can be used in hard automation, robotic, and high production semiautomatic applica-tions. Optimized GMAW-P waveforms are readily available to use on aluminum, carbon steel, high strength low alloy steel, stainless steel, and nickel alloys.

Tweet. #2. 01-12-2011, 05:13 AM. Stick stainless 309 or 316 is a pain in the arse, for one reason, it doesnt like to lay flat like a 7018 weld when welding vertical using stick. Make sure you have a die grinder with a burr bit on it (single cutt burr bit works best on stainless), and grind down the hump in the middle of the weld before you run ...
