There are a ton of youtube videos and websites about how to make a DIY battery tab welder - however none of them seem to have any information on what type of eye protection to use.
I know that some people making small tac welds with regular welders will line things up and then just look away or close their eyes while pulling the trigger - is that what's supposed to be done here as well?
I know that the big welding helmets have auto darkening adjustments but it takes a small period of time for the adjustment to happen - perhaps the battery weld would be so quick that it would not be worth using a helmet for this?
Below is an excerpt from Jim's Blog showing one of the upgrades he made to his version of the welder. It also shows him using the welder but he does not appear to be using any helmet or goggles.
