HI EVERYONE. I HAVE A BROBLEM WITH MY AMADA LCG 3015 3.5 KW CO2 LASER. IT CAN'T CREATE A LASER BEAM. I HAVE ALARM MESSAGE LASER GAS OR PSU. OUR ELECTRONIC GUY INSPECTED PSU'S AND LOOKS OK. WE CHECKED LASER GAS BOTTLE, PUT NEW ONE AND NOTHING.
WE NOTISED THAT THERE IS A BIG LASER GAS PRESSURE...
How thick is material you would like to cut with foil? I can check tomorow my parameters buth one thing is important for youre fiber laser, foil must be intended for fiber laser cutting.
Does your cutting head standing firmly? Thry pushing it by hand in all sides (one side at the time) and see if allarm clears. Can you move cutting head?
If the material is not pierced all the way and it starts to cut, this could happen for thick material. Your gas pressure for pierce is too big. Reduce it to 0.08 and thry.
Sorry for late responce.
If you have another cone you can replace it and see what happens. Does this happens on all materials and thickneses?
Once, l had problem with material while piercing. One pierce good, next half inch above. Waterial was a problem in my case.
