Reci 100watt Laser Beam is Ring Shaped

Hey folks.

Just received a laser cutter Reci W2 and noticed that the beam coming out of the tube (before the 1st mirror) is ring shaped. The focused beam is not ring shaped though, but I presume lens would focus the ring to a point anyway. Question is though does the unfocused ring mean the tube is faulty somehow?

Power supply is underpowered at 80watt. Could this be the cause? Also can under powered PSU cause any damage in the future to the Tube or PSU?

Amazingly the lens in the laserhead was installed upside down. Is it also possibly that lens at the end of the tube could be the wrong way around? Does this come off does anyone know? I have cleaned but not attempted to remove it.

thanks in advance for any answers
