Grizzly DD7542 Operation, Variable Shade, Sensitivity Dial, Welding App Current Amp Shade No

Operation

"ON" Switch

Push the "ON" button on the side of the helmet. The auto darkening feature will activate and stay active for 15 minutes after the last bright light. You will need to push the button again when this occurs. Before welding raise the helmet up to a bright light source and make sure the auto dark- ening feature activates. If it does not, push the button and check again. If it still does not work see the troubleshooting guide at the end of this instruction sheet.

Variable Shade

The shade chart below shows settings that can be used for various welding processes. We rec- ommend that you start ANY welding process at #12 or #13 and reduce the shade as needed for safety.

Welding App.	Current Amp.	Shade No.
	<40	#9
	40-80	#10
Stick Welding	80-175	#11
	175-300	#12

	250-400	#13
Plasma	<50	#9
Welding	50-200	#10
	200-400	#11

Sensitivity Dial

As previously mentioned, the auto darkening lense can be made more sensitive or less sensi- tive to bright light produced by welding. In most applications, the dial should be set to middle of its range. However, the setting should be changed when used in extreme conditions. Below is a list of applications and settings that you can use as a guide for making adjustments.

Stick Welding	Mid Sensitivity
MIG Welding	Low-Mid Sensitivity
(short circuit)
MIG Welding	Mid Sensitivity
(pulsed or spray)
TIG Welding	Mid-High Sensitivity
Plasma Cutting/	Low-Mid Sensitivity
