Fumes & Gases
Duty Cycle: It has a 20% duty cycle, meaning for every 10 minutes, you should only weld for 2 minutes to avoid overheating. 2. Manual Highlights: Setup & Settings Ventilation: The transformer relies on convection cooling
The Good News: The manual for the Century 117-051 is functionally identical to the Marquette 70 and the Dayton 70 units. I finally found a clean PDF.
- Ventilation: The transformer relies on convection cooling. Never set the welder on a carpet or cover it while running.
- Arc Flash: Even at 70 amps, this machine produces UV radiation. Use at least a shade #10 auto-darkening helmet.
- Flux-Cored Fumes: Self-shielded wire produces heavy fumes. Manual states: Operate only in well-ventilated areas or use an approved fume extractor. Do not weld on galvanized metal without proper respirator.
- Capacitor Discharge: Before touching any internal component, the manual instructs: Short the two large capacitor terminals with an insulated screwdriver for 10 seconds. Residual charge can deliver a nasty shock.
- Input: L1 (black) → Power switch → Transformer primary
- Transformer secondary → Rectifier diodes → Output to gun (positive) & work clamp (negative)
- Control circuit: Switch → Wire speed PCB → Drive motor (24V DC)
- Thermal switch (NC, opens at 150°C) in series with primary
