QDLASER HY-T150 CO2 Laser Power Supply 150W for Co2 Laser Engraving and Cutting Machine3. Operation Instruction (1) Laser Tube connection: (Referring to Power supply and laser device's connection diagram figure1) High voltage terminal(HV+) of HY T150 power supply should be connected to the positive pole of CO2 laser device. Current circuit of the power supply shall be connected to negative pole(laser output terminal) of laser device, through an ampere meter or directly.

3. Operation Instruction
(1) Laser Tube connection: (Referring to Power supply and laser device's connection diagram- figure1) High voltage terminal(HV+) of HY-T150 power supply should be connected to the positive pole of CO2 laser device. Current circuit of the power supply shall be
connected to negative pole(laser output terminal) of laser device, through an ampere meter or directly.
(2) Connection of control signal: The control signal shall be reliably connected to control terminal of the power supply HY-T150, after connecting the DAC output signal and TTL signal of external computer with the power supply, the laser device shall work as
expected. If the laser lamp can not work properly, should check the control signal is correct or not(include check the voltage specification and logic), if use PWM control as power control, make sure f≥20KHz, Amplitude (peak value) ≤5V, check and make sure protection switch WP connection is correct at same time.
(3) Voltage of power input: HY-T150 's power input of the power supply shall be 220VAC/50Hz. If 110VAC is needed, please specify when placing order.
(4) Others: A group of protection switches are also reserved for detection of water switch, fan switch, open-enclosure protection and so on.

4. Caution
(1) Water cooling system should be working properly when switching on laser device.
(2) Circuit of high voltage output should not be open! (High voltage output terminals(positive and negative poles) shall be properly connected to positive and negative poles of laser device, respectively.
(3) Attentions should be given to avoid any electric shock after the power supply being switched off (The insulation safety requirements should be 40KV between the terminal of output and "G").
(4) Well-grounded three-pole receptacle should be used to supply power to HY-T150 power supply. The enclosure should be well grounded to avoid electric shock.

Sturdy paper plates
I ordered "too" heavy paper plates. A paper plate is used daily to zap my bacon in folded over paper towel. I use them daily for various kitchen tasks.

Less expensive than local grocery stores
This pack of paper plates works out to be a lot less expensive than my local grocery, and unlike the grocery store, Amazon always seems to have it in stock.
These are your basic, thin paper plate. We use them with plastic paper plate holders to add support. I think it's a good deal.

Cheap, very thin, and weak
They are very cheap and very weak. You need to double and triple up to use them, so it isn't worth it.
