Watch The Set-up and Performance


20-40 Amp Cutting Range

The ForceCut® 42i only weighs 36lbs. and runs off 110/220v 1 phase voltage making this unit the most portable plasma cutters on the market for its power. The ForceCut® 42i offers quality cutting of up to .78” (20mm) and rough cuts of up to .98”(25mm)!

Digital meters

 The ForceCut 42i uses digital meters to allow customers to adjust the unit to any amperage quickly, accurately, and easily.

Built In Air Filter And Regulator

Built in gas/air filter and regulator provides air filtration of airborne particles to keep the ForceCut 42i cutting clean and efficiently.

Thermal Overload Protection

LONGEVITY has included thermal overload protection which informs the user when the duty cycle has been exceeded shutting down the unit in a safe matter until ithas been cooled to adequate temperatures to proceed cutting.

Pilot Arc Technology

With the ForceCut® 42i plasma cutter, the Pilot Arc system automatically senses loss of voltage, auto-ignites the Pilot Arc allowing for the torch head to maintain an arc when cutting.

Blowback Arc Start/ CNC Ready

The ForceCut® 42i starts the arc by creating an internal spark to ignite the plasma arc. By using air pressure to move the electrode against the nozzle, the ForceCut® 42i creates the arc without any need for high frequency. This allows for easier CNC table integration without the worry of interference.

Efficient IGBT Inverter Technology

IGBT technology has taken the welding industry to newlevels. It gives us the ability to offer smaller units that weigh less while increasing efficiency.

42i Review by Steve
I had always wanted a plasma cutter to compliment my welder. Having a cutting torch I could cut metal but wanted to be able to do more.

After some research into plasma cutters I knew I wanted something that would cut thicker metal than some of the smaller name brand machines and found this site. I liked the 42i more than the rest both for it's size and the ability to use 110 or 220 power.

I've had mine for over 2 years now and while I don't use it a lot, it works great every time. I've cut metal over 1/2" with very smooth cuts. It's got a learning curve, but only because I tend to learn as I go. Follow the directions and you'll be cutting like a pro.

The price for what you get was another plus and makes this machine pretty affordable for what you get. Since purchasing this machine, I only use my cutting torch to heat and bend metal now.

I do suggest purchasing extra consumables to have on hand.

Overall a great machine, reasonable price and well worth having in the shop. (Posted on Dec 22,2015)

endless frustration at start... Review by Michael
Well after waiting for my new cutter to come in it finally came, and me being me I wanted to try it out right away. When speaking to the sales rep over the phone he told me that the unit has had the issue with the air fitting corrected, that is half true, it is a new connector from what are seen on the videos but it is not a standard NTP fitting... (at the time of this review I am still unsure of what it is.)

Also a few of the items that were suppose to be included with the item were missing. The main part being the 110v adapter, thankfully I have one from another piece of equipment in my shop but still need to get another one for this machine.

And finally to top this all off, I try to call customer support to get this all figured out and I get the run around going on nearly an hour now to just get to talk to someone.

All I want is to use this machine, but it seems as if something is not letting me. (Posted on Mar 24,2014)

Great Buy Review by Brent
I got my 42i about a month ago and I love it.Reaching for the 42i for a quick cut verses draging out my torches is no contest.I still use my torches on my mobile welding truck but that will change as soon as I get a gas compressor.In my opinion you wont go wrong with this dual voltage powerhouse. AND yes it will cut an inch thick. (Posted on Mar 17,2014)

"Butter Knife" Review by Toby
this machine is a hot butter knife cutting frozen butter. Awesome machine. would recommend buying extra scrap you will need it from all the fun you will have cutting. (Posted on Oct 18,2013)

Super portable and powerful cutter Review by Frank
This machine that I acquired two months ago helps me to do a lot of cutting job in a shop. No any complaint! It is very portable and at the same time powerful plasma cutter. I note that Longevity customer service is on the high level.

Powerful portable plasma cutter Review by Andrew
I bought this plasma cutter because I often have to cut some metal parts. Its portability and dual voltage allow me to use the machine in different sites. With this cutter my cutting job turns out more accurate and clean. Pilot Arc provides longer life of consumables. (Posted on Apr 24,2013)
