Q: Can I use the BLW 280 SSW for TIG welding? A: Yes, but you require a high-frequency arc starter box and a DC TIG torch. The manual warns that scratch-start TIG is possible, but tungsten contamination is likely due to the open-circuit voltage (OCV) range of 65-85V.
Q: What is the fuel consumption at 280A? A: The manual quotes approximately 3.2 L/hour at rated load. At idle, consumption drops to 1.1 L/hour.
Q: Why does my BLW 280 SSW have a voltage selector plug? A: The SSW model allows you to switch between 110V and 220V AC output by physically rotating a Camlok plug inside the output panel. Changing voltage while the engine is running can destroy the windings—shut down first.
Q: How do I interpret the warning lights? A: The panel has three LEDs:
| Code | Description | First‑step check | Typical remedy | |------|-------------|------------------|----------------| | F01 | Flame failure | Verify fuel pressure, check spark electrode gap (≤ 1.5 mm) | Clean or replace electrode; clear fuel filter. | | F02 | Over‑temperature | Check water pressure, verify flow sensor | Bleed air, clean pump impeller, ensure correct water flow. | | F03 | Low water level | Inspect level sensor, water circuit pressure | Re‑fill system, replace sensor if faulty. | | F04 | Over‑pressure | Look at pressure‑relief valve, check expansion tank | Reset valve, replace if stuck, verify correct set‑point. | | F05 | Fuel pump failure | Listen for pump motor, measure voltage | Replace pump motor or check wiring. | | F06 | Electrical fault (IEC‑bus) | Check control‑panel connectors, ground continuity | Re‑seat connectors, tighten ground strap. | denyo blw 280 ssw manual
