# ESAB Edge R

This page describes how to integrate and set up communication between the ESAB Edge R power source and SmoothTool X.

## Hardware Configuration

SmoothTool X supports ESAB Edge R power sources via the *EtherNet/IP* protocol.

**Requirements before starting:**

- **ESAB Edge R** power source equipped with an *EtherNet/IP module*
- Ethernet cable
- PC for configuration and job creation

### Connecting to the Web Interface

Connect an Ethernet cable between your computer and the **Ethernet (cloud) port** (port 1).

![ESAB Edge R front-side Ethernet (cloud) port](https://hub.smooth-robotics.com/wp-content/uploads/2026/09/manual-power-sources-esab-front-ports.webp)

Open a web browser and navigate to: **edge.local**

Log in using the following default credentials:

| Field | Value |
| --- | --- |
| Username | admin |
| Password | gateway |

Enter a new password (at least 6 characters) and select **Save new password**.

### Setting the IP Address

Navigate to **System configuration → Robot setup** and open **EtherNet/IP settings**.

![ESAB web interface — EtherNet/IP settings](https://hub.smooth-robotics.com/wp-content/uploads/2026/09/manual-power-sources-esab-web-interface-ip.webp)

Enter a suitable **IP address** for the machine's EtherNet/IP interface according to your network setup.

Connect the **EtherNet/IP module port** (port 2) to the robot using another Ethernet cable (or reuse the cable from the previous step).

## Software Configuration

Once the hardware is configured, add and connect the ESAB Edge R in SmoothTool X.

### Add the ESAB Edge R

Tap **SmoothTool X Settings** from the Application view. In the sidebar, under **Components**, tap **Power Sources**, then tap **Add new power source**.

 ![Power Sources page with the Add new power source button](https://hub.smooth-robotics.com/wp-content/uploads/2026/09/manual-power-sources-esab-edge-r-power-sources-tab.webp)

In the **Add power source** dialog, select the **ESAB** tile and choose the **ESAB Edge** model, then tap **Add power source**.

### Configure the ESAB Edge R

Fill in the configuration fields:

| Field | Description |
| --- | --- |
| Custom name | A name to identify this power source. |
| Power source IP address | The EtherNet/IP address you set under **EtherNet/IP settings** in the ESAB web interface. The robot uses this address to communicate with the power source. |
| Signals | The device map the power source uses — **Standard PLUS 16 Bytes** or **Standard PLUS 40 Bytes**. The 40 bytes map enables fine tuning on the Power Source Parameters node. |
| Equipped with wire break | Enables the wire-break option. |
| Compressed air connected | Enables the blow-out-air option. Only enable if an external device is connected. |
| Configure parameters in the software | Controls whether program nodes override the power source parameters at runtime — see [Configure parameters in the software](#configure-parameters-in-the-software) below. |

Caution

Determine whether your power source uses the **16 or 40 bytes** device map and select the matching **Signals** option. If the wrong option is selected, the connection will fail.

When done, tap **Done** to save the power source.

#### Configure parameters in the software

The **Configure parameters in the software** toggle controls how welding parameters are applied:

- **Disabled** (default) — the power source keeps the parameters set on the machine; program nodes do not override them.
- **Enabled** — program nodes override the power source parameters at runtime, letting you set welding parameters per node from the Power Source Parameters node.

### Connect to the ESAB Edge R

Back on the **Power Sources** page, expand the new entry, tap **Selected** to make it the active power source, then tap **Connect**. When the connection is established, a connection status tag is shown on the entry.

Note

If unsure about the IP address configuration, set the EtherNet/IP interface IP to **192.168.0.1** and subnet mask **255.255.255.0**, connecting the module directly to the robot (not through a router). Then on the teach pendant go to **Settings → System → Network**, select **Static address**, and enter IP address **192.168.0.2** with subnet mask **255.255.255.0**.

## Programming with SmoothTool X and ESAB Edge R

When **Configure parameters in the software** is enabled, you can adjust the welding parameters per node from the program tree.

Select a weld node (e.g. Weld Seam) in the program tree and open its **Power source** (General) tab to set the parameters. The parameters apply when the program reaches that node.

| Identifier | Description |
| --- | --- |
| Job number | The library job saved on the ESAB Edge R that the power source should run. |
| Fine tuning | Enable to override the job's parameters below. |
| Wire feed speed | Desired wire feed speed. |
| Voltage/Arc length offset | Voltage or arc length offset relative to the library job. |
| Voltage | Sets the welding voltage directly. Applies as an absolute value when fine tuning is enabled. |
| Transfer parameters | Sends the current parameters to the power source. Available once connected. |

Note

**Fine tuning**, **Wire feed speed**, **Voltage/Arc length offset** and **Voltage** need the **Standard PLUS 40 Bytes** signal set. On a machine running **Standard PLUS 16 Bytes**, the node shows only **Job number** and **Transfer parameters**.

### Manual power source controls

The manual controls live in the **Power source** popover, opened from the button in the operator screen toolbar.

 ![Power source popover showing the manual wire-control and test functions](https://hub.smooth-robotics.com/wp-content/uploads/2026/09/manual-power-sources-esab-edge-r-manual-controls.webp)

When connected to the ESAB Edge R, the following manual controls are available:

| Control | Description |
| --- | --- |
| Forward | Feeds the welding wire forward. |
| Backward | Retracts the welding wire. |
| Error reset | Clears the current error on the power source. |
| Gas | Opens the gas valve for the duration of the press. |
| Cool | Runs the water-cooling function for the duration of the press. |

Two further buttons appear only when their configuration option is enabled: **Air** (blow-out air) when *Compressed air connected* is on, and **Wire Break** when *Equipped with wire break* is on.

Warning

Connected to a power source that provides the option to control the wire. Do not use these functions without ensuring no harm can come to people or material. Make sure the area around the welding torch is clear before use.

#### Simulation

The **Simulation** toggle at the top of the popover runs the program as a dry run: the robot executes the full program and motion path, but the power source does not weld (no arc, wire feed, or gas). Use it to test a program safely, then turn it off to weld for real.
