So Ive been trying to teach myself to weld with my new Oxy-Acetylene setup. While I am usually fairly autodidactic (self taught), there are some things you just need someone to show you or explain to you. I have hit a wall in my learning. I am dead consistent in what I do, so I do the exact same thing each time and end up with the same problems. While consistency is a good thing, I dont always know what to do to overcome the problems I have. I am a member of one of the welding forums, so I wanted to be able to show them what I am doing and ask questions.Ive got the taking pictures thing down, but its pretty hard to take pictures of yourself while welding and I think that a video of me welding would make it easier for the experienced welders to diagnose my problems. I didnt want this to be a huge expenditure, so I wanted most of this project to be things I already own. Here are the items I put together to build this project:- A Kodak play>full waterproof HD 720P video/still digital camera. This thing is about the size of a pack of cards, takes HD movies, and is waterproof to a few feet. We got it because the boys have constant video projects at school and I am not about to let them take the nice video camera to school.- A mini gripper-style tripod. I actually didnt end up using this. It occurred to me that rubber-encased tripod next to several thousand degrees of heat might not be a good idea.- I originally planned to just build a bracket to attach the camera to the tripod. I ended up also building a base for the bracket, instead of using the meltable tripod. Of course, there is plenty of scrap aluminum around The Aerodrome Studio, so that didnt cost a dime.- A piece of leather to protect the camera from the heat, sparks, and slag from welding. This came from a welding neck guard
which is essentially a square of leather you attach to the bottom of your welding helmet to protect your neck. I think it was all of $6 US at the LWS for this scrap of leather and 3 little metal clips.- While I was at the LWS, I picked up a glass, shade 5 welding lens and a plastic, clear protective lens. About $4 US at the LWS.- Misc. hardware bits. About $3 US at Ace Hardware.- Oh, and I convinced Mrs. Machine_Punk to let me have one of her elastic hair doolybobbies.Overall, that comes to about $13 US for new parts, plus a stack of stuff I already had, for the Machine_Punk Welding Cam.A picture of the back of the assembled rig. Notice the controls on the camera are easy to get to and there is at least one layer of protection (leather or welding lens or metal) all the way around the camera...A picture of the front of the assembled rig. It ain't pretty, but it meets all my design criteria. I was able to leave a tiny spot open so the microphone can pick up the sounds of welding too, which may be critical to diagnosing some of my issues...The camera rig...all set up in it's native environment, ready to make a video of me, welding on a steel coupon...Without the welding lens on...With the welding lens on...A link to a video of taking the welding lens off as the camera adjusts to different light levels...My major concerns were: - It needs to be inexpensive and use one of the cameras I already own.- There needs to be protection for the camera from heat and other welding dangers.- Be able to see the welders-eye-view (i.e. from under the hood, what I see as I am welding).- Needs to be able to handle glare from the sun (I usually weld outside and usually weld into the sun, so the items I am working on are well-lit (not in my shadow) ).- I would prefer to be able to hear the welding noises (in case that is important for diagnosing a problem)
but still want to make sure the camera is protected.I think I met all those requirements in this project. Ive been thinking about it for a few weeks and thought through a couple of designs for each camera I have. This is what I finally decided on. Id like to make a couple of design changes to this eventually, since it is difficult to get the camera in and out of the bracket, since it just uses an elastic band to hold it. Id like to make a holder which cradles the camera and makes it easy to get in and out.KevKevin / Machine_Punk from The Aerodrome Studio - Lincoln PowerMIG 210 MP - Meco N Midget w/custom welding station - Vintage Victor 100Current Projects: The Aerodrome Studio
Reply:so how do you hold a lens there too? good thinkin so farMiller thunderbolt 250Decastar 135ERecovering tool-o-holic ESAB OAI have been interested or involved in Electrical, Fire Alarm, Auto, Marine, Welding, Electronics ETC to name a just a few. So YES you can own too many tools.

Reply:Dump the green welding lens and get an actual ND filter made for photo work. You can buy them in rectangular pieces as well as screw on lens mount. The ND will knock down the light without altering color. Add a clear UV filter to help with outdoor and welding arc UV which can give a bluish, washed out look to your images.The rest of the set up is very cool!PapaLincoln Idealarc 250 (circa 1962)Lincoln Weldpak 155 w/Mig KitLincoln Squarewave TIG 175

Reply:Originally Posted by Machine_PunkThanks for the kind words. It didn't even occur to me that there might be some lens out there specifically for photographing welding. I'll have to look into that. For now, I just wanted something cheap and available, which would allow others to see what I see...so they can tell me how to fix the issues I have. Of course, once I get those issues resolved, I'd like to actually make a few 'how to' videos. I definitey appreciate the input...I have an older Sony still/video camera that can take filter lenses, I think 52mm, that I would like to set up for this project eventually.I appreciate you taking the time to post.PS: here is a great article on ND lenses in Wickipedia...http://en.wikipedia.org/wiki/Neutral_density_filterKev

Reply:Thanks again for more info! You have given me something to think about. I was thinking about going with the screw on filters because I have a camera with screw on filters, that I can more-or-less dedicate to the project of welding videos (or change quickly to something else, if needed).I appreciate the insight.Kev Originally Posted by papaharley03Kevin,The ND filters are like sunglasses for your camera. They come in different strengths. .3, .6, .9 and they aren't specifically for photographing welding. They are for knocking down the light coming to the film or sensor so that one can stay within the sweet spot of the lens or desired exposure settings. For optimal image quality, get the camera as close as possible and don't use zoom if your camera has it. You don't have to buy a screw on filter, they can be bought as I stated in rectangular glass or plastic. Those normally get put into a matte box but will work by using the same method you used for attaching the welding shade.Food for thought.Papa
Reply:Duuude...well done. I like your setup (even cheaper and easier than mine). Is there some place we can see videos you shot with that setup? Originally Posted by T E BI {GTAW} Tig this up for my ipod out of SS and i can take pix by remote control with this Dell bluetooth keyboard
