# Lorch S-Series/ROBO MICORMIG

This page describes how to integrate and set up communication between Lorch S-series and MICORMIG power sources and SmoothTool X.

## Hardware Configuration

SmoothTool X is compatible with the Lorch S-series and the robotic MICORMIG. To set up communication between the software and a power source, the following items are required:

- One of the compatible **Lorch** power source models:
  - Lorch S3 (MOBIL) PULSE XT
  - Lorch S5 PULSE XT
  - Lorch S8 PULSE XT
  - Lorch ROBO MICORMIG
  - *If in doubt, contact your local Lorch supplier or the Smooth Robotics team.*
- A **LorchNet Connector**, ordered in its **EtherNet/IP** version. It is an add-on: it does not come with the machine and has to be ordered separately. SmoothTool X talks to the machine through this connector, not to the power source directly.
- Ethernet **M12-to-RJ45** cable from the LorchNet Connector to the robot — NBC-MSD/2,0-93E/R4AC SCO (GTIN 4046356774895) or similar.

Note

All four models are driven through the same integration and share the same configuration fields, welding methods and value ranges. The model you pick does decide one thing: which synergic program table **Synergic mode** browses, since each machine ships its own set of weld programs. Pick the tile that matches the machine in your cell.

### Installing the LorchNet Connector

Install the LorchNet Connector by following its own instruction manual. For details about the connector, the cable or the power source itself, contact your local Lorch dealer.

### IP Address

SmoothTool X communicates with the Lorch power source over the **EtherNet/IP** protocol. Select a valid IP address for the LorchNet Connector. The address must be on the same subnet as the robot.

Set the address from the power source itself: the interface settings are reached from the machine's control panel, where the IP address can be specified. Follow the procedure in the LorchNet Connector's own documentation.

If that procedure is not available, the connector's address can also be set from a PC with the **HMS IPconfig** tool:

1. Download HMS IPconfig from the Anybus website and install it. If it does not start after installation, right-click it and choose **Run as administrator**.
2. Connect the LorchNet Connector to the PC with an Ethernet cable.
3. Open the tool and refresh the device list — the connector appears in it.
4. Select the connector and enter its **IP address** and a **Default Gateway** on the same subnet.
5. Click **Apply** to transfer the settings to the module.

![HMS IPconfig with the device's IP address and default gateway highlighted](https://hub.smooth-robotics.com/wp-content/uploads/2026/09/manual-power-sources-hms-ipconfig.webp)

Tip

Smooth Robotics suggests **192.168.102.8** for the power source, **192.168.102.3** for the robot, subnet mask **255.255.255.0** and default gateway **192.168.102.1**. If you prefer your own addresses, keep the same network ID — the first three octets — on every device, and give each a distinct host ID.

Note

There is no protocol to select on the connector itself. The LorchNet Connector is ordered as the EtherNet/IP version, and that choice fixes the protocol.

Note

The robot itself must also have an IP address on that subnet. If the robot network is not configured yet, SmoothTool X prompts you to set it up when you save the power source.

## Software Configuration

Once the hardware is configured, add and connect the Lorch power source in SmoothTool X.

### Add the Lorch power source

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-lorch-power-sources-tab.webp)

In the **Add power source** dialog, select the **Lorch** tile and choose your model — **Lorch S3 (MOBIL) PULSE XT**, **Lorch S5 PULSE XT**, **Lorch S8 PULSE XT**, or **Lorch ROBO MICORMIG** — then tap **Add power source**.

 ![Add power source dialog — Lorch model selected](https://hub.smooth-robotics.com/wp-content/uploads/2026/09/manual-power-sources-lorch-add-power-source.webp)

### Configure the Lorch power source

Fill in the configuration fields:

| Field | Description |
| --- | --- |
| Custom name | A name to identify this power source. Prefilled with the model name. |
| Power source IP address | The IP address you set for the power source interface. The robot uses this address to communicate with the power source. Ensure it is set correctly; otherwise the robot cannot connect. |
| 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. |

**Done** stays inactive until both the custom name and a valid IP address are filled in. When done, tap **Done** to save the power source.

 ![Lorch power source configuration page](https://hub.smooth-robotics.com/wp-content/uploads/2026/09/manual-power-sources-lorch-configuration.webp)

#### 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 weld node's Power source tab.

### Connect to the Lorch power source

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.

## Programming with SmoothTool X and Lorch

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** tab. The parameters apply when the program reaches that node.

The Lorch integration offers three ways of setting the weld, and the node opens on the chooser so you can pick one:

| Method | What it does |
| --- | --- |
| Job number mode | Runs a job stored on the power source. |
| Synergic mode | Picks a weld program from the machine's synergic table, through guided steps or by number. |
| Job parameter fine-tuning | Sets voltage and wire feed speed directly, in manual MIG/MAG. |

  ![Power source tab for Lorch showing the three welding methods](https://hub.smooth-robotics.com/wp-content/uploads/2026/09/manual-power-sources-lorch-weld-parameters.webp)

A method must be picked before the node counts as configured. Each method has its own page with a back arrow to the chooser, and each page carries its own **Transfer parameters** button.

Note

Only the values of the method you picked are sent to the power source. Switching methods switches what the node writes; the values you entered on the other pages stay stored on the node, but are not used.

### Job number mode

Tap **Job number mode** to run a job stored on the power source. The page is titled **Job**.

| Identifier | Description |
| --- | --- |
| Job number | The job stored on the power source that this node runs. Between **0** and **99**. |
| Transfer parameters | Sends the current parameters to the power source. Available once connected. |

  ![Lorch Job page with the job number field](https://hub.smooth-robotics.com/wp-content/uploads/2026/09/manual-power-sources-lorch-weld-parameters-job.webp)

Note

In Job number mode the power source uses the parameters stored under the selected job; arc length correction, dynamics and slope cannot be overridden. Use **Synergic mode** if you need to override those.

### Synergic mode

Tap **Synergic mode** to weld from the machine's synergic program table. The page is titled **Program**.

There are two ways to choose the program, side by side: type a known number into **Synergic line number**, or tap **Guided setup** next to it and step through **Process**, **Material**, **Gas** and **Wire diameter**. Once a program is selected, the picker shows a summary of what it is, and the pencil next to it reopens the steps.

 ![Lorch Program page with the synergic line number and its parameters](https://hub.smooth-robotics.com/wp-content/uploads/2026/09/manual-power-sources-lorch-weld-parameters-program.webp)

| Identifier | Description |
| --- | --- |
| Synergic line number | The weld program the power source runs. Between **0** and **1023**. |
| Arc length correction | Corrects the arc length of the selected program, in percent. Between **60** and **140**, default **100**. |
| Dynamics | Corrects the arc dynamics of the selected program, in percent. Between **50** and **140**, default **100**. |
| Current *or* Wire feed speed | Selects which of the two drives the arc, then sets its value — **Current** in amps (A), **Wire feed speed** in m/min. Only the selected one is sent; the other is sent as zero. |
| Slope | Enables or disables slope. |
| Transfer parameters | Sends the current parameters to the power source. Available once connected. |

Note

The limits on **Current** and **Wire feed speed** follow the selected program: when you pick a synergic line, its own minimum and maximum replace the defaults. Until a program is selected, the fallback ranges are 0–500 A and 0–25 m/min.

Caution

Some processes can only be driven by wire feed speed — **SpeedArc**, **SpeedArcXT** and **Synergic**. Selecting a program that uses one of them locks the **Current** option out, and the node sends wire feed speed regardless of what was selected before.

### Job parameter fine-tuning

Tap **Job parameter fine-tuning** to set the weld values directly, without a job or a synergic program. The page is titled **Manual MIG/MAG**.

| Identifier | Description |
| --- | --- |
| Voltage | Welding voltage, in volts (V). Between **10** and **40**. |
| Wire feed speed | Welding wire feed speed, in m/min. Between **0** and **25**. |
| Slope | Enables or disables slope. |
| Transfer parameters | Sends the current parameters to the power source. Available once connected. |

### 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-lorch-manual-controls.webp)

When connected to the Lorch power source, the following manual controls are available:

| Control | Description |
| --- | --- |
| Forward | Feeds the welding wire forward. |
| Backward | Retracts the welding wire. |
| Gas | Opens the gas valve for the duration of the press. |
| Air | Runs the power source's air-clean function for the duration of the press. |
| Error reset | Sends a reset-error signal to the power source. |

All five are press-and-hold buttons, and they stay inactive until the power source is connected.

The popover also shows two status readouts from the machine under **Parameters**: **Communication ready** and **Power source ready**.

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.
