Wireless instability, operator safety, and long-distance machine control are major challenges in heavy-duty welding environments. This month, discover how the HT4P IDEC Safety Commander™ helped a custom metal fabrication customer deploy a reliable 20-meter wired control solution while preserving the flexibility of their Android-based welding interface.
The customer’s challenge:
A customer developing a heavy-duty welding cell for custom metal fabrication required a portable, tablet-based primary control system. The operator needed to move around and due to the possible hight of the unit, 20 meters in cable was require by the welding controller to avoid intense heat, UV radiation, and spatter. However, the metal-rich environment created significant wireless interference, making Bluetooth and Wi-Fi connections unreliable. In addition, they needed the freedom to run their own custom program/interface on a commercial tablet while meeting strict safety standards (hardwired E-stop + enabling switch). Most off-the-shelf pendants offered neither tablet flexibility nor long-range wired reliability.
The initial system in place:
Our initial consultation focused on three core challenges:
1) Overcoming wireless interference with a guaranteed reliable, wired connection over 20 meters of cable.
2) Enabling the use of the customer’s custom welding interface (developed on an Android tablet) without locking them into a proprietary system.
3) Safely allowing the operator to stand away from the controller while maintaining full machine control and safety functions.
The solution we provided:
The HT4P IDEC Safety Commander proved the ideal solution. It overcame possible wireless interference by providing a stable, wired LAN communication via its built-in USB/LAN, no dropouts, no latency. It fully supported the customer’s custom program/interface by acting as a rugged, safety-rated holder for most commercial tablet, allowing the customer’s own welding control app to run seamlessly. And crucially, it enabled safe operation from the controller, with the hardwired emergency stop and three-position enabling switch meeting ISO 10218 robot safety standards even at that distance.
The customer now runs three welding cells in one of its many locations with HT4P units, eliminating wireless reliability issues, preserving their software investment, and keeping welders safely at a distance.
