    150 w RECI LASER TUBE burns a circle not a dot

    Hi there,
    It hasn't engraved right for a week. So i went to realign it. I taped the second mirror, nothing was visible on the tape. So i taped the first mirror, this is what i get.
    what do you think the issue is?
    Ps: When i first got it, it burned a hole out of the tape and cardboard.
    Thank you.

    I had the same pattern and replaced the tube. I had a low cost tube and assumed it couldn’t be repaired. Problem is that it won’t focus properly
    I believed it was from lack of coolant.

    I contacted RECI on this 150 watt tube's burn and their response was that the gas was consumed and that a replacement tube was needed.

    You could also use a CO2 laser power meter probe (like Mahoney brand) and measure the output power.

    Also, I would visually inspect my RECI 150 watt tube's visible light illuminated in the tube during operation to see if anything else was going on (I had two of its power supplies fail on me), and also at lunch time my AC voltage varied from regular working hours (as my neighbor's were all machine shops and powered down at lunch)--I lost 5-10 volts and the output power fluctuated wildly due to the power supply's circuitry.
