How can I test an auto darkening helmet.
I bought an auto darkening welding helmet at Harbor Freight.
How can I test it to make sure it works.
I took it outside yesterday evening and looked at the sun thru it.
I put my hand over the lense and could see thru the lense.
I moved my had and it went dark for a second then back to clear.
I don't think the sun was bright enough to keep it dark.
But how can I be sure it is working ok.
