Low budget plasma setup, what do I need?

depending on Y length i thik the wrong Side of the Y bar used will bend as it is made for Wx WY use and in this setup i see it is the Force in Wz of the bar so not the best way to go
is it a 45x90mm bar we taking in Y or smaller and what is the max width between the X fix rails

to get a calculation on

if a Mechanical touch off is used i think it wil ltroubel

Profiles are thick wall 80 x 40 1400mm long + 800mm so the opening is 1240 by 800
This will give me plenty space to cut 1000 x 500 plates

Linear rails are 35mm for R1651 linear guides

The *arm* is 800mm long and supported with ball bearing so X is only with one rail.



So you are worried about torsion force on this arm, I can make the open arm to ride on two bearing well apart to counteract this if needed. I am not particularly worried about this as the load is not so high.

A secondary linear rail is easily fixed if needed on the other side but for now it will have to do with only one side.

I have a question regarding consumables to P80 torch.

On Aliexpress there is 3 varieties of consumables = pro / std / diy
What is the difference on these, need only 1.1mm and 1.3mm

Anybody out there that can give me some advice on the consumables?

Maybe ask the seller? Sorry I do not have any experience with those, only Hypertherm,

Maybe buy a small amount of all three and test each on the material you are going to be using.

Asking seller? Most likely as good as asking my wall at home

I think I will go for the premium type.

Those prices are not to bad,

My hypertherm consumables cost me $7.58 AUD for a single 45amp nozzle and you have to buy them in packs of 5. I mostly use the 125 amp nozzles and they are $14.85 each.

Ouch that is costly.
Just ordered one pack each 1.1 + 1.3mm (20 nozzles total) Premium for ~50AUD

We pay HT and TD (ESAB) for all their R&D spending every time we buy equipment/supplies. What we get in return are good cut tables and relatively reliable equipment. With a Chinacom plasma you have to be your own R&D department.

Yes you pay more in Oz than we do here for HT consumables, about 33% more without factoring in exchange rates. I find that the HT consumable life is so good that their cost per cut unit distance is quite low. I also buy the 25 packs of nozzles and electrodes because a big part of my cost is shipping because there is no welding shop here.
