I buy this fan, used

Here is an image of the details, on the top of my blower.



Should be all the electrical info on there!

The reason I want a dimmer, is the slide which I already have on my blower doesn't work too well. Especially when it comes to lighting the forge. The blower is just too powerful.
Another reason is that the blower itself is incredibly noisey and gets on my nerves a bit. I'd rather just have the fire 'ticking over' most of the time.

So 400W max rating on this is too low for my 450W blower?

Yes. Because start current several times bigger than working. 

Buy this module (4 kWt) and be happy.

May be it will be usefull idea. You need only hairfan, box, metal pipe 1" or little more, some clay. I forge outdoor because have not exhaust pipe, and dont want to broke roof.

My shop made in old shed (or barn) in Boyarka near Kyiv, Ukraine

Can I forge this, and forge weld the gear ?

Depends; if the hottest area is oxidizing then NO, if it's reducing then yes.  Make sure there is a good bed of hot coals below the piece and a good bed of hot coals above the piece as well.

Coals must be fresh? "old" coals (that fire some  minutes) can make oxidizing flame?

With my students the issues are generally by the 2's: too oxidizing, too cold, hitting too hard. Welding is really much much easier to lean with a teacher in person instructing you.

Mister Thomas! Do I  must put cable inside white colour glowing maximum heat coals? 10X10X10 cm to 15X15X15/ Maximum heat area? Or just put near it? I will try now.

I have no possibility to get lessons with teacher. ((((

how deep is your fire? 6", 8", more? What is your set up like?  Air Source?  Size of charcoal pieces? There is no one "relative position of tuyer,  thickness of coals layer, cable, coals from above cable" How the forge is designed and how the air is supplied can change things quite a lot. (As does the skill of the forge welder, the late Billy Merritt once  demo'd a weld at a temp I would think was a bit cool for forging! OK! So what is essential thing? What landmark I must find? Sometimes I have successful welding. But I dont know, why.

Can someone draw a sketch of relative position of tuyer,  thickness of coals layer, cable, coals from above cable? I read many posts about oxidizing/reducing flames but cant understand how steel can get hot enough to weld out of hottest part of fire. I use selfmade charcoal. Excuse my English. Thank You!

I weld a lot of cable, once you know how, it's pretty easy. The two big things are getting the cable clean, and getting it hot enough. You can clean the cable in the forge, with a lot of wire brushing, heating, and fluxing. You'll be able to tell when it's clean by when you stop getting a bunch of crud out when you brush it.

How deep must be tue iron in coals? And is I must too put cable in maximum heat place, white heat? Or little higher? My wire cable "dry", I cant get "wet, smoky" surface. Why so?

hey, I've got my eye on an electric forge blower, but the speed controller is missing, can anyone tell me where i can get a speed controller from or what the proper name for them is, and how much it's likely to cost...

Or is it better to just put a valve in the air way and have an on/off switch?

thanks all

What type of motor Your blower has?
