I think we pushed some buttons, cool.
Still it's not a good idea to use these in the laundromat, especially dirty ones, I've been in plenty of hotels/apartment complexes, there's always that stupid lint under the washers and dryers and everywhere else when they don't clean the place well, even cleaning well is sometimes not easy under the machines. My personal dryer and washer have lint and money under them, so I would think that the throw off from welding would be a great way to set part of the building on fire. I actually save my dryer lint since nothing else makes such a great firestarter for a camp fire or fireplace, it burns great!
So that being said go outside, if you want to protect people from seeing it hang a tarp up. I actually don't even weld at home usually, I actually enjoy the company of my friends' place for welding, and I can even pawn it off one of them since he likes it and I'm useful enough that he's even willing to do it for FREE Aahahaahhhhahahahaaaa!
Back to the point even the cheapest hf welder will be good enough, this is rather thin stuff after all, if you get something too beefy it will eat through your bike tubing and vaporize thin wire doing the splattering everywhere too hot weld thing, don't forget you're cooking flux too, arc welding rules partly apply.
I might add that that's a neck pinching rent, if everyone around you is paying the same rate and still acting like a bunch of f***ing drugged out apes then MOVE!!
