In this paper, a low-cost reverse-gliding arc three-dimensional reactor with local materials and a homemade voltage source was proposed. This system works by pumping out argon gas while mixing in atmospheric air. The spectral properties of the resulting arc were investigated, as well as the calculation of electron temperature and density. The process of mixing air with argon gas is a novel method for obtaining nitrogen gas at a low cost and with ease of access. Nitrogen gas has numerous applications, and the findings are promising for future applications.

A low-cost reverse flow plasma system powered by argon gas pumping was built using homemade materials in this paper. The length of the resulting arc change was directly proportional to the flow rate, while using the thermal camera to examine the thermal intensity distribution and demonstrating that it is concentrated in the centre, away from the walls at various flow rates, the resulting arc's spectra were also measured. The results show that as the gas flow rate increased, so did the ambient temperature. The results show that the medium containing the arc has a maximum temperature of 34.1 ˚C at a flow rate of 14 L/min and a minimum temperature of 22.6 ˚C at a flow rate of 6 L/min.
