Machine torch maximum cutting capacity

[Normsthename]

I have a Hypertherm 1000 with a machine torch that I will be using with my CNC setup in s few days time!
The manual lists a recommended cutting capacity of 3/8" (10mm) and a maximum of 1/2" (12mm) with 3/4" (19mm) available if I do an edge start.

But with a Hand torch it will do a a recommended 3/4" (19mm) and a maximum of 1" (25mm) with 1 1/4" (32mm) Severence cut.

Why the big differences with the machine torch, has anyone cut thicker with the machine Torch.

Thanks in advance

With a hand torch you can tilt the torch when starting the cut, and a machine torch can't tilt. This keeps the slag out of the tip. I've done 1/2" with mine in auto. I've gone 1.125 in aluminum with an edge start when I needed to rip up a sheet.

The Hypertherm Powermax machine torch and the hand torch are based on the same design and internal physics. In reality...they have exactly the same capacity...however machine torches are meant to be mounted on a machine...and typically have to pierce perpendicular to the plate....somewhat limiting the pierce capability as compared to a hand torch that can easily be tipped to pierce at an angle...allowing molten metal blowback to miss the nozzle and shield. Also....mechanized cutting applications can easily have higher duty cycles...as machines do not normally have to rest.

Hypertherm has a full line of industrial mechanized systems that are rated at 100% duty cycle, use a variety of different gases to fine tune the cut quality on different materials, cost less to operate due to higher cut speeds and longer consumable life, produce better cut part accuracies....these machines are not available with hand torches.
