Can you have too much plasma cutter?

[TMGT]

The problem I found with the bigger units is the torch size becomes a bit bulky for smaller work. I've seen multiple torches available for the larger hypertherms.
They can be turned down but the fine cut consumables give a narrower/cleaner cut on thinner material as apposed to the higher amp consumables.
I have to disagree about 5/8 being the max clean cut for 220v machines though, I've seen the Hypertherm pm65 or 85 cut 1.25in+ cleanly off 208-230v.

I totally agree. My old Miller 30 amp Spectrum plasma cutter was WAY nicer for (hand held) cutting 10 gauge and lighter.

This was partially due to the smaller torch and tip but MOSTLY because of the better quality flexible hose/cable assembly. Current models have extremely poor quality stiff lead assemblies.

Picky person that I am, I also hate the light gauge work (ground) cable they provide. Almost impossible to coil up neatly. I upgraded mine to 6 gauge for under $1 CDN /foot.

Terry, looks like your stand swivels... I assume you like that feature? Also where did you get the spiral wrap? That looks nice and heavy duty.

Hi Mark. I was feeling creative and recycled the swivel base from an old office chair. I like the swivel feature but it's not necessary (IMO).



The spiral cable wrap came from the local shop that supplies all my hydraulic hoses and fittings.

Aha! I will visit my local hose shop... thanks for the tip. I recently found a hole in the wall place that built me a custom air line for my blast cabinet.

I forgot to mention.... I used 14 feet of wrap for my 20 foot torch lead, leaving the first foot and the last five feet UNwrapped.

Reading my mind again... I saw the first foot but was kind of wondering what you found to be optimum on the torch end. :thumbsup:

I have Hypertherm 85 single phase 240VAC and 4x8 CNC table. The 85 should cut at least 1.25" with edge start. It will pierce .75".

I think the only way a plasma cutter/MIG/whatever would be too large is if it will not physically fit in its allotted space somewhere or can't be moved if portable. I subscribe to the "Tim the tool man Taylor" philosophy of most things in my life

Yes. Like having Pam Anderson for an "assistant".
