Argon gas refill controls spatter and reduces post-weld slag
The low ionization potential of argon improves arc stability and reduces spatter accordingly. The recent new welding power technology controls the splash of CO2 welding. Under the same conditions, if the mixture gas is used, it can further reduce the spatter and expand the welding parameter window.
CO2 welds tend to protrude outwards, resulting in over-welding, which increases welding costs. Argon gas mixture is easy to control weld formation and avoid wire waste.
