Flap wheels Hello, I use a lot of the Walter enduroflex flap wheels in either 60 or 80 grit, they are a little more expensive than some , but they last longer and give very good surface finishing , have to be careful how hard you lean on the grinder cause they can take welds off faster than a regular grinding wheel. the plastic backing can be shaved or trimmed to get the maximum use out of the

I use the Walter 40 grit flap discs. I also have some 60, 80, 120 discs. They are great and last a long time. As it gets worn down you just have to take off the orange plastic. This gives the edge back and it continues work great. There are three arrows which allow you to refresh the disc.
I do not use many flap discs if I do it is for blending on stainless pipe sometimes steel, and even then I find myself using a three-inch Roloc disc in the Milwaukee high-speed right angle die grinder usually. But I do buy them and I use them in my 4 1/2″ Milwaukee right angle grinder, I get them from these guys, I get the zirconium discs.

I do have a miller syncrowave 200 TIG welder and did some of this welding with that (cutting perfect shaped patches to elliminate gap and be able to TIG from there is a whole nother subject and skill I need 2 master 2!!!)), but I had up to 5/16″ gap in some places on this tube, so most of it was MIG’ed with the Lincoln. Please help!!!
Just a quick point that’s likely already been mentioned – but with the number of people posting here with issues learning aluminum Tig it’s a common theme of using a flap wheel to clean the metal – my experience is that while a great tool for general post weld blending / removing burrs / taking off sharp corners etc they are not good for pre-weld use as it’s very easy to get the glue that
2275. For something like that I would use a 9″ grinder with a rubber backed sanding disk- 80 grit. If there are any bad high spots on the weld take it down first with the 4 1/2 or 5″ grinder. Hold the 9″ as flat as possible to the metal. I have 4 or 5. 9″ grinders and use them alot for this type of thing.
Home Depot, (Canada), has always had a pair of Bosch grinders for $99. I get a couple of these every few years – its nice to have different discs set up and ready to go instead of looking for and changing parts. get a good helemt – yes. Mine, (Miller), has a replaceable rechargeable battery and a function test button.
