The Lee 90947 Pro 4-20 Electric Melter is a workhorse for serious bullet casters who want speed, capacity, and reliability at the bench. This 110V melter holds roughly 20 pounds of lead—enough to keep you casting for hours without constant top-ups—and its 700-watt tubular heating element delivers fast melt times and quick recovery between pours. Whether you're loading pistol or rifle rounds, the Pro 4-20 is built to handle volume without the fuss of stovetop casting or constant temperature babysitting.
Built around Lee's proven high-efficiency design, this second-generation melter features a dependable remote-sensing thermostat housed in a dust-tight enclosure, so you're not fighting shop debris or environmental swings. The adjustable mold guide lets you position any mold quickly and accurately, and a generous 3¾ inches of clearance under the spout accepts all standard bullet molds plus most sinker molds. The new micro-adjustable flow control valve responds instantly to a screwdriver turn, giving you fine-grained control over pour speed and consistency—critical when you're chasing tight groups or uniform bullet weight.
Temperature range is 450 to 900 degrees Fahrenheit; most casters start around 650 degrees and adjust from there. The front-mounted, replaceable valve spout reseats with a simple screwdriver turn, keeping maintenance simple and downtime minimal. If you're casting in volume and want a compact, efficient electric melter that doesn't demand constant attention, the Lee Pro 4-20 earns its place in any serious reloading room.
| Model | Lee 90947 Pro 4-20 |
| Lead Capacity | Approximately 20 pounds |
| Voltage | 110V |
| Heating Element | 700-watt tubular |
| Temperature Range | 450–900°F |
| Clearance Under Spout | 3¾ inches |

The Pro 4-20 provides 3¾ inches of clearance under the spout and accepts all brands of standard bullet molds plus most sinker molds. If you have an unusual or oversized mold, measure its width and check it against that clearance dimension.
The melter ranges from 450 to 900 degrees Fahrenheit. Most casters find 650 degrees a good starting point, then adjust up or down depending on fill-out quality and your specific alloy. Aim for the lowest temperature that gives you consistent, well-filled bullets.
The 700-watt element provides fast melt times and quick recovery between pours, though exact timing depends on starting temperature and ambient conditions. With 20 pounds of capacity, you can cast for extended sessions before needing to top up.
Yes. The front-mounted, replaceable valve spout reseats with a simple screwdriver turn, and the flow control valve adjusts with a screwdriver as well. The dust-tight housing protects the thermostat and heating element from shop debris.
