Laser Cut Parts for the hobby shop! 2kw Laser 4 in 1 Welder & Cutter machine cutting parts! Part 1

[@diyfiberlaser]

Very cool! For 1/4" plate, I use Oxygen at about 9 psi. You can probably find a cut settings chart for your laser source online to help dial in speeds, height, gas type and pressure. A component distributor told me that the water chillers used in welding units only cool the laser source line, while the cutting head line just circulated room temperature water, whereas the chillers for cutting machines cool both lines. You might keep an eye on it when doing longer cuts, to make sure the nozzle isn't overheating. I'm looking forward to seeing it with height control!

Oxygen is definitely on the to do list. The cooling system is routed to the welding head per the supplied documentation with chilled water. I also know this to be true because I could feel the welding head getting cold when I was dialing in the chiller temp. Thanks for the tips!

What an awesome idea!

[@kwrigg]

Thank you!

[@ClayFRocker]

This is a cool idea but 90% of the benefit of fiber vs plasma is speed. Those heavy fiber frames + servos make them incredibly fast. Still really cool though, not trying to shit on your idea. I'm jealous of the laser welding specifically, it just looks so satisfying.

The welder makes anyone look like a pro!

[@TimWelds]

That’s an awesome integration, nice work!

[@trebronikum]

Nice man. I also thought of this. Bought a 2kW 4 in1 laser a month ago, will do the same conversion. My only concern is i think these welder heads won't tolerate well if the laser reflects back itself.

[@kwrigg]

Thought of the reflection being an issue too but I make sure I’m not pausing on the pierce and have the machine moving instantly to keep the laser beam from reflecting back. Just make sure the lead in is long enough to let the laser get all the way through before you get to the profile lines.

your a clever guy, well done

[@kwrigg]

Thank you!

with 2kW fiber laser to have clean cut with Air you can cut maximum 1,2mm thick plate. Maybe 1.5mm. Over this thickness you you use Oxygen. 2mm like 0.9Bar, 2,5mm-10mm use 0.5-0,7 Bar! When you have rough edges it means the Oxygen is too much! And big problem is that rust! Laser doesn't like when plate is rusty. You must prengrave the countur first before cut if plate is rusty like that!

[@kwrigg]

Thanks for the tips! I will try Oxygen in the future.

[@AUMINER1]

impressive conversion :)

[@kwrigg]

Thank you!

Muito bom... Como vc fez para diminuir o delay. Tenho uma hand laser de 1500w, mas tem um delay de 1.2 segundos entre apertar o gatilho e abrir o laser... e as vezes dá uma pequena variação nesse tempo... +- 0.5sec Vou cortar chapas de aço inox de 1.2mm. Sobre a pressão do ar comprimido... abaixo de 100psi cria muita escória na borda. Obrigado. Penso em usar O2 puro.

English Translation: "Very good... How did you do to reduce the delay? I have a 1500w hand laser, but there is a 1.2 second delay between pressing the trigger and opening the laser... and sometimes there is a small variation in this time... +- 0.5sec I will cut 1.2mm stainless steel sheets. About compressed air pressure... below 100psi creates a lot of slag on the edge. Thanks. I'm thinking about using pure O2." On the Laser unit control screen, there is a setting for delay of cutting from flow of gas to start of laser. I didn't mess with it and just made sure my lead in was long enough. If you have variation in start time, it might be in the safety clamp not getting a good connection between your cut piece and gun. I'm running right around 100 psi but might be dropping under 100 psi while the laser is cutting so my next step is upping the psi. Im planing on using oxygen when i try cutting thick steel as I have read this will increase the thickness available to cut.

Can give the link where you bought the machine laser? 😊

[@kwrigg]

www.noualaser.com/ this is the company, I bought it on Amazon.

[@normansteinkemper1024]

Which Controller do you use on your plasma table?

[@kwrigg]

Mach3

[@normansteinkemper1024]

Thanx, are you happy with ?

[@kwrigg]

@ yes! I think these laser machines are the future with all the things they can do!

[@normansteinkemper1024]

You are right , i am in the Situation that my old Controller is broken, so i will modernize it with mach 3 or myplasm. Can you describe the connection to the laser? Is it only 5 v dc from the Controller?

[@kwrigg]

@ I went to a 5v relay from your pin out of the breakout board for your spindle. Than the trigger input for laser goes to the relay.

[@Chauvin-r9u]

Somehow I don't think I would use that thing with my hand anywhere in front of it nor would I ever point it towards myself I don't care if the damn things unplugged unhooked or just plain broken. I worked for a big company that was using a laser system and they guaranteed us that it would never be on with the laser pointing at us so much for their software we set a blueprint on fire and after that we were out of there

[@kwrigg]

You definitely have to be careful with it, and it will start heating up anything you are pointing it at quickly 3 feet away when you are pulling the trigger.
