Hitbox CT 520 - Attenuation and Gas Flow Settings; Indicator Lights and Panel Schematic

- 6 -
5.2.3 Attenuation parameter adjustment:When completing a section of welding and ending the
arc, in order to ensure good forming, the current is required to gradually decrease to stop. This
parameter is used to adjust the decay time of the current.
Note:When using the "foot pedal" control, this knob is turned counterclockwise to "0"
5.2.4 After flow gas time parameter adjustment:The workpiece after welding is oxidized by the
heat, so after the welding is stopped, the argo
n gas blown by the welding torch is used for a
certain period of time. This parameter is the time after the exhaust gas is adjusted, and the
maximum time can be 10 seconds.
5.2.5 In “MMA” mode,only the welding current, the hot start, arc force, and other functions do
not work.
5.3 Indicator light
Overheat protection indicator: When the welder is working continuously, for a long time or at a
high current, the overheat protection function is set to prevent damage to the device due to
internal heat. When the light is on, the digital display shows -E2, stop working, but not Shut
down, after about 2-3 minutes the device can be automatically restored.
