    Slats cleaning

    Does someone have a special machine to clean the slats on the table or you just do it with the zipgun? Those machine are very expensive. Does it worth the price? Did you eared about brass slats?

    Hi i recently did some marking on half inch stainless steel and it work fine. Now they think to give me some marking to do on mild steel. I have a 4kw fiberlaser and the lowest power i can go is 400 watts. Is that possible to do it and what gas will be best nitrogen or oxygen? Is there kind of...

    Nitrogene tank

    We have a 2000 liters tank. Twice in a short time we completely empty it. So we had to switch to the emergency bottle by the time they came to refill. In the same time the quality of the piece we cut were so so. Would like to known if emptying the tank can produce some humidity or bad quality...

    Focal lens and gas pressure

    I am using a fiberlaser and I often cut stainless steel.From what I read the focal lens can take hight pressure gas. Nitrogene is used for that. The guys who sold that machine told me always used high pressure with fiberlaser. Example: 11ga at 18bar, 12ga he put 20bar, .250 at 22bar. I have...

    Focal lens

    I would like to know what to expect between a focal lens 125mm and a focal lens 250mm? Is there a difference in focal lenghts I should use. I mean for example if I use -3.3 for focal lenght on ss with the 125, do I have to use, let say -4.3 with the 250. Is the power increase?

    Rusted steel and focal .250

    Hi How rust affect the cut on mild steel? For the same parameters on others sheets no problems but today try a really rusty one and man I regretted putting that sheet on the table and start (on top of it) a full program (60X120 in). I understand pretty good the focal on SS but a lot less the...

    Problem solve

    Good news. The sensing problem I had was the calibration. Yes RPosty I check the connector and it was ok. Thamks for the tip anyway. The tech guy arrive early and check that. He actually show me how to do it. The emgeneer from Ermaksan said it might happen after they change the head...

    No good news for Ermaksan fiber 2kw

    Since January this year I had problems to cut pieces with no dross and been worst and worst to the point can't go throught the materiel. They came last Friday and it seem to be the collimator. They are going to change all the head. Can't wait to see the difference, if there is. My question is...

    Always dross on fiber laser ermaksan 2kw

    I'm an old operator of a plasma machine and I just changed my seat for the seat of our newest machine. A fiber laser 2kw ermaksan. Well I'm a newbie on the laser. What a world of difference. First I love laser way to think, I feel useful and use my brain to obtain the result. I'm crazy about...
