If you’re always on the move, getting a portable plasma cutter is the right move for you. Having a light-weight, hand-held machine just allows you to get more done than having something massive that is just a pain to deal with.
Since you came to this page specifically looking for a portable option, you may also be interested in checking out our comparison chart. It allows you to easily say “okay, this is how much I want it to weigh at the very most, and these are the dimensions I don’t want it to be bigger than.” That saves you a bunch of trouble if you know that you are either mainly comfortable carrying a certain amount, or if you know that you want your plasma cutter to be fitting in a specific space on your truck, where there is just a limited amount of space.
A lot of people are extremely happy with the Hypertherm Powermax 45, which stands at 36 lbs, but the Powermax 30 is an even lighter option at 21.4 lbs. Then it very much comes down to your personal preferences, or if you have some types of metal, or thicknesses that you know you will be dealing with a lot.
There are also a bunch of both Hobart, Everlast, Thermal Dynamics and Miller Electric models that the pros are using out there. From Miller Electric, you will find that the Spectrum 625 X-TREME is a strong contender at 21 lbs.
