Prepare for installation

Note: For detailed instructions on the preparation work, refer to Preparation Work Before You Use xTool MetalFab Laser Welder.

Power supply

xTool MetalFab Laser Welder 1200W requires a 220 V – 240 V AC power supply, and works at a rated power of 4200 W. An individual branch circuit with a current-carrying capacity of 25 A or above is recommended.
Requirements on electrical facilities vary with power cables. Please consult a qualified electrician before installing the device to ensure that the device is installed in accordance with local electrical codes.

Note:
■ Ensure that the current-carrying capacity of your circuit meets the requirements. Do not connect the product to a standard household circuit, as it may damage both the product and the circuit.
■ Ensure that the welder is powered separately. Do not use it with other high power equipment on the same circuit.
■ To ensure safety, it is recommended that you install a 25 A air circuit breaker between the power supply and xTool MetalFab Laser Welder 1200W.

Workroom

Ensure that the workroom is well-ventilated.

Shielding gas

xTool MetalFab Laser Welder 1200W requires the use of shielding gas. Supported gas types include nitrogen and argon, and the gas purity must be over 99.99%. Please prepare gas cylinders or gas generators (not provided) that meet requirements.

Laser welding, cleaning, and cutting have different requirements on the supply of shielding gas.

Note: 
■ To perform laser welding or cleaning, please prepare a gas flow meter in addition:

■ To perform laser cutting, please prepare a gas pressure reducing valve in addition:

Cabling diagram

The following picture shows the cabling diagram of xTool MetalFab Laser Welder 1200W. Please follow the detailed step-by-step instructions to complete the installation.

Installation

1.     Place the main unit

Place the main unit in a proper place, leaving a gap of no less than 10 cm at the front and back to ensure good ventilation and heat dissipation. Step on the pedals of the four caster wheels to lock the main unit in position.

2.     Connect the shielding gas cylinder

(1) Insert one end of the tube into the shielding gas inlet on the main unit.

Note: 
■ After inserting the tube, attempt to pull it out. If the tube remains securely in place, it is connected properly.
■ To remove the tube, push and hold the collet of the shielding gas inlet and pull out the tube.

(2) Install a gas regulator on the shielding gas cylinder (or gas generator).

(Installing a gas flow meter on a cylinder is used as an example.)

Note: Tighten the nut to prevent gas leakage.

(3) Connect the other end of the tube to the cylinder (or gas generator).

Note: Do not open the gas cylinder valve yet. Open it only before laser processing.

3.     Place the welding head

(1) Assemble the welding head cradle.

(2) Place the welding head on the cradle.

4.     Connect the workpiece sensing cable

Insert the connector end into the port for the workpiece sensing cable, and attach the clamp on the other end to the workpiece to be processed or a conductive worktable connected with the workpiece.

Note: It is strictly prohibited to attach the clamp to the graduated tube of the welding head.

Safety interlock loop
A safety interlock loop exists between the welding head, the workpiece, and the main unit. Only when the welding head is in contact with the workpiece can the safety interlock loop be closed and allow the welding head to emit laser beams.

5.     Connect to a power supply

Cautions:
■ Ensure that the current-carrying capacity of your circuit meets the requirements. Do not connect the product to a standard household circuit, as it may damage both the product and the circuit.
■ To ensure safety, it is recommended that you install a 25 A air circuit breaker between the power supply and xTool MetalFab Laser Welder 1200W.

Note: The connection of power cables varies with their standards. The following instructions are for US standard power cable only. Power cables of other standards should be connected by a professional electrician in accordance with local electrical codes.

Attach the round connector of the power cable to the main unit, and the other end to the power supply.

US standard:

Note: If the power cable you receive has a PUSH button at the connector, directly push the connector into the power port. To remove the connector, press and hold the PUSH button and pull the connector out.

Caution: Ensure that the device is grounded. If the power supply is not grounded, please use an earth cable (not provided) to connect the device to a grounded object.

6.     Check the emergency stop button

Ensure that the emergency stop button is released. If it is pressed, rotate it to release it.

Emergency stop button
If an emergency occurs, press the emergency stop button to shut off the machine.

After dealing with the emergency, rotate the emergency stop button to release it.

7.     Insert the key

Insert the key into its designated port.

Note: You can use the key either as an access-control key or a remote interlock connector.
Access-control key
Removing the key can disable the machine's processing and related functions.
Remote interlock connector

8.     Power on

On the back panel of the main unit, turn on the power switch to power on the device.

Unlock the device

(1) The first time you turn on the device, you will see a QR code displayed on the touchscreen. Scan the QR code or visit s.xtool.com/doc/hj/si to watch the safety training videos.

(2) After watching the video, input the serial number (SN) shown on the touchscreen to the web to generate an unlock password for your device.

(3) On the touchscreen of your device, tap Enter the password. Then, enter the password generated to unlock your device.

Note: Ensure that all users watch the safety training videos before using the device. You can access the videos by visiting s.xtool.com/doc/hj/si.

Calibrate the focus for the welding head

(1) On the home page of the touchscreen, tap System settings and check whether the Focus scale reference is the same as the actual value on the graduated tube. If the values are the same, no calibration is needed; if they are not, go to step (2).

(2) Open the fastener, push or pull the graduated tube to adjust it to the reference value shown on the touchscreen.

Note: If you need to connect the wire feeder, refer to “How to Install and Set the Wire Feeder?” for detailed instructions.
