Detailed Answer
Yes, heavily. Welding fumes (metal particles + smoke) cause: 1. Sticky keys (particles getting in); 2. PCB contamination (conductive); 3. Housing corrosion (acidic smoke). Countermeasures: IP6X dust protection, regular air-blow cleaning, storage away from welding areas. The LDER LD series has an IP67 dust-proof design; XINGJIA likewise. Shipyard remotes need more frequent cleaning.

| Countermeasure | IP6X + cleaning |
| Storage | Away from welding |
Note:Add a dust cover to remotes near welding areas.
