What is it :p

[Zephod]

Ok. Just piquing interest. What's this (I know but do you)?

Somebody practicing welding for the first time?

With flux core wire

It's a work of art! A masterpiece!

Actually, whatever it is, it's built to purpose and will probably do the job quite nicely, all jesting on this board aside.

Isn't that part of your ventilation system using muffin fans?

Geoff scores. It's part of my ventilation system using a CPU fan. Before I install this, I'll test it first. I might have to upgrade to a bilge vent fan. To be honest though, I see little to be gained from short powerful bursts of air over gentle continual ventilation.

Edited because I was cranky. :-/

FYI, I used to build computers in cases for a living and I can tell you that muffin fans aren't your best bet for ventilation in terms of CFM. Fantastic ceiling vent fans move a ton of air and are already 14"x14" and don't need a special welded heavy metal chute to install. I have bus friends that hardly even have to use their A/C because these fans move so much air.

No offence but hope you can grind better than weld.


Just kidding. As long as it works.

I made a heat exchanger for my hydronic heating system to put in my plumbing bay out of a large muffin fan and the heater core from a Ranger pu. I built the enclosure out of plywood. it works quite well to keep the bay warm when needed.

I've never quite understood heat exchangers. They're probably like Schlieren photography - hard to describe and master but ultimately very simple.

I'd love to see photos.

My welding IS getting better. I'm finding the 6011 rods don't flow as well as I'd imagined. When I grind my welds, I do find slag enclosures but the welds seem pretty strong. The more I weld, the more I feel I should have gone for gas rather than arc.

I don't know. It brought up heat exchangers which is worth talking about.

You should have brought the flux core wire welder for the same price as the stick welder.  A 6011 rod is for penetration welds with little flux.  A 6011 is for thicker metal than you are working with.  You would have better welds with a 7014 stick.

if you can flat pass everything...7024 makes pretty passes...easy peasy. can't flip over/around a battle ship

i used to break in first timers with it and then have them move on from there...

[Zephod]

The rods I can get easily are 6011, 6013, 7014, 7018. I've got some 312 for welding stainless to mild steel. I can use 1/16, 3/32 but 1/8 is a challenge for my welder.

all my kozy heat exchanger have 1 or 2 muffin fans and work really good . yes they do not move lots of air but they use very little power and are quiet . nice slow movement of warm air and they take up very little room . it is better to pull the air then push it with this type of fan

are these kozy heat exchanger's still available for sale I need 2

You can find them at hydronicheaterrepair.com also check out suremarineservice.com I buy all my parts from them.
