Shade selection
Set the darkness shade according to the welding job to be carried out as follows:
- Press the UP and DOWN buttons to select the required shade level.
- To select the suitable shade number, follow the instructions contained in Table 1:
Sensor sensitivity
Depending on the welding process and the ambient light, select the minimum amount of light required for the front sensors to
enable the protective screen guard as follows:
- : For high current welding in a bright welding environment or in an environment with other sources of interference.
- : For low current welding or in a low light environment, especially in case of low current argon arc welding.
- : For most indoor and outdoor welding operations.
Delay time
Depending on the welding process, set the amount of time required by the mask to switch back from full dark to full light.
The delay time ranges from 0.1s to 2.0s. Set the delay time as follows:
- The delay time set between 0.1s and 0.3s is suitable for spot welding, short welding or seam welding.
- The delay time set between 0.8s and 2.0s is suitable for high current welding or preventing eye fatigue from electric arcs or
close viewing of incandescent pieces.
- The medium value is suitable for most indoor or outdoor welding jobs.
