Tips/Techniques fume extractor MIG gun

[CWret]

While looking at the "Buy Canadian" thread in the "off-topic discussions" section - I noticed @quitereal suggested a Kent fume extractor MIG gun.

- Does anyone have experience with Kent? (and this gun?)
- Does anyone have experience with any fume extractor MIG gun?
- I see Tweco has one called their Centrovac - any experience with that one?
I have not chased down pricing - but am guessing this is an expensive upgrade.

I have a homemade ceiling-mounted fume extractor that works pretty well. On my to-do lists is to improve the adjustability of the control arm for the extractor hose. Kent’s short demo video looks like their extractor gun is very effective and always extracting right where you need it. (pictures - the 400cfm extractor fan is in the attic and exhaust outside, the wood box, hanging on the ceiling, houses a 1200 cfm repurposed furnace fan that sucks through a couple of filters and recirculates air within the garage.

I've used a regular kent mig gun before, they're well built, solid, can take abuse, skookum as frig son of a guns. Can't speak to the fume extractor one. I wonder about shield gas getting sucked away when the extractor is integrated into the nozzle.

from my little research into fume extractor MIG guns - they don't suck out shielding gas, are not heavy or cumbersome, and work very well, but they are expensive
