one small candle than to curse the darkness.
AND 500W OF HALOGEN IS EVEN BETTER.

Got tired of missing the joint with a bead so made this light fixture. If you look closely you can see it swivles in two joints and slides up and down.

Designed a standardized hinge joint for such thing a couple of years ago. 7/8" hole saw through a box tube. Weld in a 3" x1/2" NPT pipe nipple, clean out with a 5/8" bridge reamer, and use a 5/8" CR hinge pin. Fast, simple, strong and works good.

Turning on the 500W light would trigger my auto-darkening helmet to dark, making it useless. Solved that by adding a simple relay in the welder (Miller 225 MIG). Found a 24v line that opens the gas valve when the trigger is pressed. Used this to energize the new relay that closes and supplies the light. Pull the trigger - light comes on! (The light is plugged into the wall for the photo, otherwise it would be off.)

You are going to find that halogens are awfully hot work lights.

It sounds like you are only using the light when you're MIG welding? Try turning down the shade on your helmet http://bbs.homeshopmachinist.net//smile.gif Actually, I have the same problem too.. I've got my shade set to the lowest and I still have a hard time seeing the joint sometimes when using my MIG.. Does the halogen help out a lot?

They are excellent for setting up fiberglass or working on a vehicle outside in -20. I have a 500 watt unit in a square tube cage I built complete with a place to wrap up the cord.

Also good for warming your feet if your shop is cold (put one on the floor aimed at your standing spot)

An old welders trick is to run soapstone down the seam or lap,when the light is not good or your eyes are worse.
Try it.

Yes it can get hot, but only having it on while there is an arc reduces the duty cycle on my bald spot.

Ajustable hood down all the way. 9

Would like a lower wattage focused spot but don't know what. Low voltage needs a 6 to 10 amp transformer that they are quite proud of.

Have you considered useing a 12v halogen? A lot cheaper to run (and cooler) with plenty of illumination also.
That set up you have there looks good and sure beats mine; a piece of plywood on an old office swivel chair base -- my relocatable weld table http://bbs.homeshopmachinist.net//smile.gif

Try a theater supply place. I think a 3" lamp with a Fresnel lens would do quite nicely for you. Wouldn't be as hot--they run about 150-200 watts usually, and you can mount them to a chunk of unistrut, or actually to whatever you please. They're quite handy.

Thanks for the pic's. I like your angle grinder hanger, I'll have one this weekend for sure. What a pain trying to keep up with them!

Not all halogen lights are designed to be turned down due to heat. We do that with the lights in my business and it ruins the housings, sockets, wireing !! The small display bulbs others have mentioned are designed for that service and far less heat.

I built the design similar to what Frank Ford uses for my welding table as it will double as a portrait light. The slopes will have crinkled tin-foil flatend out and stapeled as reflectors. For 460 watts expended I get 1800 watts of soft light(no shadows). Watts not to like about that?

Here it is without all the HomeDepot $7.00 apiece bulbs. ( later found the bulbs at Target at 2 for $7.00)
