Hypertherm Powermax 1250 G3 New Plasma Cutter

4x4 Shop By: Add comments

My current hypertherm powermax 600 has served me well, and any issue I had Hypertherm tech support was AWESOME in helping me fix the problem. Thus why I new my next plasma cutter would be another hypertherm unit. I’ve decided to go with the Hypertherm Powermax 1250 G3 for increased cutting capacity and updated technology.


I sold my PlasmaCam CNC plasma cutting unit because I was moving and would not have a place to use it for at least two years and in this sale I also sold my plasma cutter the Hypertherm 600 unit. A couple weeks after I had the unit sold I decided to grab a Hypertherm Powermax 1250 G3. I had to re-wire it because it was setup for a 4 prong 220v outlet and I only utilize the 3 prong “old school” welder plug outlets.

This is the original / old plug that was on the unit prior to me swapping it for a standard 3 prong welder plug.


Once I swapped it over, and got it working on my power I tested it out and let me tell you the 1250 G3 series cut “smoother” feeling than my Hypertherm 600. I`m not sure if it was due to the increased power because I was running it at the power of my 600 or if it was due to the newer G3 technology in this Hypertherm unit.  So, for whatever reason it DID cut smoother than my hypertherm 600, and boy did it cut smooth! I was REALLY impressed! Here I thought I was only replacing my 600 with a more powerful unit and it turns out the 1250 G3 actually cuts “smoother” too. I was amazed the first time I used it, and it’s continued to make me happy ever sense. I have not yet gotten a new CNC Plasma table but when I do you can be sure that the Hypertherm 1250 will find it’s home on my CNC plasma table. I`ll probably get a machine torch this time too!

Enjoy these pictures of my Hypertherm 1250 G3 Plasma Cutter 🙂

This is a picture of the wires and air coming in from the front of the plasma cutting unit.


This shows the incoming power distribution area as well as other electronics inside the hypertherm 1250.


Close up of the incoming power and distribution inside the unit.


Bottom electronics on the back side of the circuit board for the hypertherm 1250 plasma.


Front panel and controls on the hypertherm 1250 g3 plasma cutter.


Cooling fan on the inside of the unit on the back side of circuit board and cooling fins.

Air lines and circuit board inside the hypertherm 1250. Looks like big-rig truck brake lines used internally for air control.


This is the back of the Hypertherm 1250. You will notice electronic inputs for controlling the unit from a computer as well as the on/off lever and air input. The air input has the optional hypertherm water/air filter on it. It should be noted that this is NOT the only air/water filter used, and should not be the only source of seperating the air from the water when using a plasma cutter. Plasmas rely on clean, dry air and these units while making the air slightly less moist do NOT do a good enough job. Sure the air will work but you will go through consumables MUCH FASTER than if you had an electric air dryer or a much nicer drying system setup.


The top of the Hypertherm 1250 is similiar to the top of the Hypertherm 600 that I used to have! It’s got great drawings of the torch head as well as consumable part #s so you know what you need to order when it comes time to replace worn out consumables.  Also it includes warning information as well as contact information for Hypertherm.

  3. What are the air consumption (l/s or gpm) and pressure (psi or bar) specifications on this unit?
    This info will much be appreciated!
