Low-cost Open-Source Voltage and Current Monitor for Gas Metal Arc Weld 3-D Printing. Journal of Sensors Vol. 2015, Article ID 876714, 8 pages, 2015. doi:10.1155/2015/876714 open access

Arduino open-source microcontrollers are well known in sensor applications for scientific equipment and for controlling RepRap 3-D printers. Recently low-cost open-source gas metal arc weld (GMAW) RepRap 3-D printers have been developed. The entry-level welders used have minimal controls and therefore lack any real-time measurement of welder voltage or current. The preliminary work on process optimization of GMAW 3-D printers requires a low-cost sensor and data logger system to measure welder current and voltage. This paper reports on the development of a low-cost open-source power measurement sensor system based on Arduino architecture. The sensor system was designed, built and tested with two entry-level MIG welders. The full bill of materials and open source designs are provided. Voltage and current were measured while making step-wise adjustments to the manual voltage setting on the welder. Three conditions were tested while welding with steel and aluminum wire on steel substrates to assess the role of electrode material, shield gas and welding velocity. The results showed that the open source sensor circuit performed as designed and could be constructed for <$100 in components representing a significant potential value through lateral scaling and replication in the 3-D printing community.
