A new high-tech membrane is made of high-quality steel and is more stable and more flexible than conventional filters, also more environmentally-compatible because only inert gas and electrical power are needed for its manufacture.
How to MIG weld 1 } Turn on the machine and adjust the settings. For my purpose the bottom two dials at the most important. They refer to the Voltage (how hot the wire is) and Meters per Minute (how quickly the spool of wire is fed through the welding gun) 2 } Attach the negative polarity clamp to the metal work table. The electricity passing through the wire must have a way of exiting the steel once it has entered. In this instance the electricity will flow through the steel into the table…
