Do these cut 2mm of magnesium metal, or will it cause it to ignite on high speed setting? Should I set speed lower, i.e. 10,000rpm? Thanks.

I only use the wheels to cut very thin metal cans at the top speed of my Dremel tool. It works very well for me. I do notice that some wheels last longer than others even though I cut the same thickness material at the same speed.Wally

I am far from an expert on this . I use them for jewelry making and cut thru stainless and silver plated silverware with no problem. Sorry I couldn't be more of a help.

I've been meaning to update my review with that info. The A/C function works fine. I am able to get decent looking beads when I tig, but this isn't a Miller dynasty. You have very few function controls. The pedal also doesn't allow for fine amperage control (since it's not a true high frequency pedal). With all that being said, if you have the patience to experiment with the amperage that best suits the thickness of your material, you should be fine. Just remember one important thing: speed. You have to move quickly once that aluminum starts to go molten. I've had some good results with this welder on A/C, but you get what you pay for, and that means operating this cheap machine can be quirky. For what it's worth, I've found that ceriated tungsten works the best with this machine.

This is an emergency type fire starter. This is not meant for cigarettes or cigars. A lighter can run out of fuel or get broken. The magnesium fire starter will not run out of fuel.

I am a stone cutter and I have cut tile,Sparks are a normal part of cutting as you are really grinding a thin section of stone(tile).FIRST make sure you are using the proper diamond blade.it will have a smoother edge then the other cut-all blades.Also Most professional tile cutting saws are water cooled.I dont think the sparks are as damaging to plastic as metal but if there are enough of them maybe.Check the under side of the blade cover every once in a while to see if there is any molten build up.I would not suggest using water to cool with this saw.Go slow and take breaks every few seconds

It's DC only. Not recommended for aluminum & magnesium. You'll need high freq AC for that. You can also check their website for other models & additional info.

M. T., I thank you for this question, and for its synchonicity. I had wondered if others were having the same question, and part of my professional work is investigating esoteric information exactly like this. The Genuine Issue mag bar appears to be identical, except a bit darker in color. Striker is good on both DM's and GI's, nice spark. But caveat emptor as always, because there are rumors on YouTube that a counterfeit mag bar is out there, and its tiniest shavings require less than an acetylene torch but more than a spark to ignite... The GI bar I tested worked well enough, though. Perhaps the tiniest bit less well than the DM, but that may be subjective. Will study this further. -GDT

I don't know but it does get hot enough to melt se ur softer metals. It burns as hot at regular propane torch. Just smaller which means less gas. Run good butane tho. Or ur waisting ur time

This unit is a drag start. So you do have to touch the metal first but don't drag it the whole time or you will burn through the tips very fast.

I have fired these at up to 400 FPS with no problems. I have not fired them any faster than that. At 400 FPS, they don't really even break up when they hit concrete.

No I'm not getting any sparks, but I haven't cut metal yet. There should be no sparks with wood.

I am not a jeweler but I think the flame tip may produce a flame front too large for small jewelry. The flame does taper to a nice point in the center but it is still large enough to solder a piece of copper water pipe and to due some smaller brazing work. There is a torch called the "Micro Torch Power Probe" that I use for automotive wiring, heating frozen door locks and etc. that you might want to look at. I bought my Micro Torch from a Cornwell dealer (an automotive tool supplier) and it is a good high quality torch with a fine point (and adjustable). Hope this helps, sorry for the delay in replying (holidays). bw I am not a jeweler but I think the flame tip may produce a flame front too large for small jewelry.

Steve, I installed the Fiamm 72112 Freeway Blaster and the Fiamm 72102 12 V High Note horns (I really think that you need both) on my 1966 MGB that has a 20 Amp Fuse and a stated max Amp draw of 3 1/2 amps. I had planned on installing a relay, but horns worked so well that I never installed it. I would simply install one or both of these horns and if they blow a fuse, then install your relay. I hardly ever use my horn, but when I do they do get Semi drivers attention. Best $30+ dollars I ever spent. I hope this helps.

Yes, the black bar is the flint. Strike the metal striker/saw at an angle lightly & it should spark for you. Don't forget to have a fair size pile of magnesium for the spark to fall in. Works in light rain also.

Can't speak to the speed tip ones as I have never used them. I have used these to drill through: Metal (up to 1/4" steel, but mostly 12 GA aluminum) Wood (plywood, particle board, and 2xwhatever pine) Plastic (PVC and ABS) Drywall The bits cut a nice clean hole and did not wander. Hope this helps.

Yup. Just wipe off any water that's beaded on it and proceed as normal. The striker should still create sparks and the magnesium shavings should still ignite. What should be dry is the tinder and kindling that you're trying to burn.. use lint from bottom of jeans pocket and kindling etc...

Best thing is to call Makita. My guess is the smaller diameter blade and slower RPM is better for metal. The smaller blade reduces the surface speed of the tooth.

First off magnesium is a flammable metal .... Its used as a means of starting a fire if you don't have any matches , lighters or any other means for fire starting .... You scrape off the Magnesium (via provided hacksaw blade or knife)into a small pile about the volume of a half thimble full or more if needed then strike the flint rod towards the pile and the sparks ignite the magnesium .. Have plenty of tinder and kindling to immediately put on the ignited magnesium and some wood to start that fire with before attempting .... Do the best job you can the first time around ....
