When we use heavy currents to weld stainless steel, there is usually a brilliant weld pool. When we finish welding, there remains strong residual light. So, you can use “delay”(function) to extend the time of the changing screen regaining light.
Use TIG inverted welder, set 5 ampere stable current, and you can make ADF sense weak and stable arc by raising “sensibility”, thus achieving the goal of changing light.
When welding, if you hope to improve work efficiency, you can make the changing screen regain light quickly by reducing the delay time. So ,you can check the welding point as soon as possible and prepare for the next welding.
