Razorcut 45 cut chart

Those are some really great looking cuts!!

Great cuts!! but .111" hot rolled? it seems more 11 gauge than 14. or am i missing something?

Could be 12ga - or 11ga - that’s in in 0.111" range.

Yea, ordered 14 Ga. sheet.
But it was thicker then the typical 14Ga. Range
I always measure anyway with a micrometer every sheet
So I can get my cut set right on my machine.

Ran 5 test cuts on .105” cold rolled steel for a project I have to do.

.105” cold rolled steel
.070” torch height
.9 Pierce Delay
.8mm Nozzle
30 Amps
Water table

Pick your poison!!
All cut really Good!
50 ipm is only one that had visible dross on the back. Rest we’re nearly dross free.
None had any dross on the front at all!
All the cuts were straight with no bevel and super clean!

Only real difference was the finished cut Kerf width.

See photos.
Looks to me like 70 ipm is maybe the winner
Why? Because there was almost no dross and the kerf width was only 0.031” & a perfect cut through with nearly non existent bevel.
Although any would be acceptable for what I do.:wink:

Looks to me like 70 ipm was the winner with a .040” measured KERF WIDTH…
Cut quality is very good with barely any bevel!
WINNER for me was 70 ipm
Although none were all that bad.

Here is the cut chart that Razorweld sent me for the 45.

Crossfire only goes 300ipm max

So I still make my own, no choice but to test cut all material first and note my own settings.
That give me the best cut results
I just made a cut with my results on my post above on .120” cold rolled, and it came out perfect, just as my test cut showed at 70 ipm

It’s the only way to dial it in for max result,

Woohoo. I’ll update the online spreadsheet with these values. Only took us a year to get this far :slightly_smiling_face:

Did they give a torch height? Or did I miss it in the picture, it is late so it’s possible I missed it

So, while the cut chart is a great aid to folks like me, I’ve yet to figure out why the pierce delay is listed at 0.01, 0.02, etc. But it actually needs to be 1 second.

PD Is what ever you need it to be.
1.0 sec is way too long on 16 18 20 22 gauge
14 12 11 10 8 Etc could most likely use 1.0 or longer to get through.
If I cut on the line, I have PD @ 0
So I don’t get a round burn hole and the line in clean

Which cut chart are you referring too?
The one from RAZORWELD. (Which isn’t much use as the ipm speeds are not compatible with the crossfire)

Or the one we started on our own in the forum?

They’re not? Why is that? I’ve found my IPM speed settings different too, but I just thought it was my cheapo Plasma cutter.

The Google docs one from the forum.

All these cutting charts are made in a lab with a $30K or more setup, not a crossfire and a back room of a garage.

Same - It looks like there was one at some point but the page no longer exists.

A little help?
