On Saturday I practiced with my new Senco Fusion 18 ga. Nail Gun (FN55AX) for the first time.
I’ve never used a nail gun before, but I found the Senco extremely easy to use.
This is a cordless gun with a permanently-sealed nitrogen gas cylinder. The battery is an 18 volt Li-ion which charges 80% in 15 Minutes and 100% in 45 Minutes. The gun has a solid feel and is very well balanced.
The selector switch has 3 options – Off, Contact-Actuation (Bump Fire), or Sequential (Trigger Pull).
There is a mechanical Depth Adjustment dial with a guide.
I attached a scrap piece of 3/4” plywood to a 2×4 scrap in Sequential mode. The nails went through the plywood with no trouble. The gun recycles in about 3 seconds after firing.
Then I attached a piece of molding to a scrap piece of 3/4” fir by bump-firing 3 nails. No problem!
I’d been looking at nail guns for a while, but I didn’t want to buy a compressor.
Paslode has cordless guns, but the gas cylinder needs to be replaced. I’ve also seen comments about the odor of the gas used.
The Senco gun comes with 1 battery and a charger in a large tool bag. The bag is zipper and has plenty of pockets and compartments both inside and out. There is a velcro strap inside to secure the gun and a moveable pad to cushion it.
First Impression – This is a quality tool that will work for years.

Nice review will file it for future use

I haven't looked at the Senco, but I do have a couple of questions, to wit:
3 seconds between charges is extremely slow. With a cheap compressor and my PC 18g nailer, I can put in nails as fast as I can pull the trigger or pick up the gun and put it down against the wood with the trigger pulled. (Think 6' with nails ever 4-6" in those three seconds). Why is this so slow?

Why not a compressor and a decent DeWalt or PC or other major brand, including Senco? For $200 you could be in business... $400 for the Senco is a bit high in my opinion.

Paslodes are built for the commercial trade, and don't need to smell pretty... they do the job.

You mention that your gun has a nitrogen tank, doesn't it need replacement or refilling?

Please don't get me wrong, but the nitrogen needs to come from somewhere, and I kind of doubt that the gun is self supplying in that endeavor.

I just did a quick Google search for the unit, and didn't see anything that hinted about nitrogen replacement.

Maybe you can give us a more thorough review after a few project uses?

My impression was that the nitrogen cylinder was a sealed cylinder (non-replaceable) and that the 3 seconds was the maximum time to repressurise it using the on board motor. The nitrogen is supposed to hold enouigh stored pressure (energy) to drive several pins. I don't know how well this would work in practice, but the tool is being sold as a commercial tool (hence the price tag), so my guess is that it isn't a significant issue.

Says the man who's pretty obviously never had to install skirting (baseboard) in confined spaces like under stairs cupboards, cellars and the like. That stink is really disgusting, not to mention toxic and bad for the environment. And why is it that many of the gas naiklers (i.e. passlode-type nailers) I've used steadfastly refuse to fire in the upside down position? Give me my cast iron (in weight terms) deWalts any day

So your saying the unit has a nitrogen generator run by a motor that can build enough pressure with an 18VDC motor to charge said non-replaceable cylinder? That's a good little generator! (Edit: I've been doing some reading and it does seem as though the cylinder is self filling by re-compressing the released nitrogen. I wonder how long it will take before the inevitable leak will develop and the gun will need to be sent back to a service center to be repaired/replaced. I think I'll stand my my assertion that I would like to see more information and a further review. Senco has definitely not been forthcoming with information about these guns and their reliability or rebuildability).

Actually, I have used the Paslodes in all kinds of tight situations. It was never a problem for me, but then mine isn't as delicate or as frilly as others. Upside down use could be a problem, but then I do try to stay on my feet instead of standing on my head.:blink:

Oh, and if you think a Paslode is toxic, consider what will happen with a gas in an enclosed area when it starts to replace the low oxygen level there in the first place. Isn't there about 78% nitrogen (20% oxygen), in the atmosphere to begin with? Adding a few more percent nitrogen and at the same time adding carbon dioxide from breathing while depleting the oxygen content sure ain't (American Colloquialism) conducive to a long and productive life. This is why the odorous chemical (ethyl mercaptan) was added to LPG and natural gas after the 1937 explosion of a school in the State of Texas, (BTW, that's in the United States).

With respect,

Dal F.

PS: I just looked up the MSDS for the Paslode gas and it seems that it's no more toxic than the air you breathe in a downtown street area.

This is from the original SENCO press release:

“A gear box and lifter force the piston and driver blade against self-contained air within the cylinder, compressing it so that when the trigger is pulled, it drives nails powerfully and consistently even into hardwoods,” adds Joe Knueven, Product Manager. “The air pressure is pre-set at the factory, permanently sealed and never needs recharging.”

I got the 3 seconds between charges from a review of the tool. Senco specifications state "3 nails per second".

I don't have the space or perceived need for a compressor. The Fusion fits my needs.
Yes, it is a professional tool, but I've learned that extra money for a professional tool is usually worth it.
