Tooltos PM260A Plating Rectifier | 30A 20V Dual-Dial, Gold Silver Copper Nickel Plating

Inconsistent plating current causes uneven coating thickness, poor adhesion, and wasted plating solution. The Tooltos PM260A Plating Rectifier gives jewelry studios and plating workshops precise, stable DC output from 0 to 30A and 0 to 20V — with dual digital dials for independent current and voltage control so you can dial in the exact parameters each metal and plating type requires.

Key Selling Points

• Dual-dial digital display with independent voltage and current controls — set and read both parameters simultaneously without switching modes or estimating from a single dial
• 30A maximum current and 0-20V adjustable output — covers the full range of jewelry plating applications from delicate gold flash plating to heavier copper and nickel base layers
• Multiple built-in protections: automatic voltage regulation, over-voltage, over-current, and under-voltage protection — safeguards both the rectifier and the workpiece during operation
• Large-area top heat dissipation design keeps the unit running at stable temperature during extended plating sessions
• Supports gold, silver, copper, nickel, chromium, and electrophoresis plating — one rectifier covers all common jewelry surface treatment types
• Available in 110V and 220V to match your workshop power supply

About This Rectifier

A plating rectifier converts AC mains power to the stable, adjustable DC current that electroplating requires. The quality of the rectifier directly affects plating consistency — unstable output causes current fluctuations that produce uneven coating thickness, rough surface texture, and poor adhesion. The PM260A uses a dual-dial digital display so you can set voltage and current independently and read both values at a glance during the plating process, rather than estimating from a single analog dial.

The 30A maximum current rating makes this rectifier suitable for both small jewelry plating tanks used in repair shops and larger production tanks used in jewelry manufacturing. The multiple protection circuits — over-voltage, over-current, under-voltage, and automatic voltage regulation — protect the unit and the workpiece if operating conditions go outside the set parameters. The compact 305×195×180mm footprint fits on a standard bench without taking up significant workspace.

Pro Tips

• Start with a lower current setting and increase gradually — too high a current density causes burning, rough deposits, and poor adhesion. Find the correct current density for each metal by consulting the plating solution manufacturer's specifications.
• Some base metals require a strike layer before the final plating metal — for example, apply a thin copper or nickel layer on steel before gold plating, as gold does not adhere reliably directly to ferrous metals.
• Clean and degrease the workpiece thoroughly before plating — oil, oxidation, and surface contamination prevent proper adhesion and cause the plating to peel or blister.
• Monitor the digital display during plating and adjust current if it drifts — as the plating solution temperature changes during a session, solution conductivity changes and current may need minor adjustment to maintain the target current density.
• Always work in a well-ventilated area and wear appropriate protective equipment when handling plating solutions — many plating chemicals are hazardous and require proper handling and disposal.

Frequently Asked Questions

What is the difference between this rectifier and a pen-type plating machine?
This PM260A is a tank plating rectifier — it powers a plating tank where the workpiece is fully immersed in plating solution for uniform, full-coverage plating. A pen-type plating machine applies solution locally with a handheld pen tip, suited for spot repairs and selective plating. Choose this rectifier for production plating and full-piece coverage; choose a pen-type machine for localized repair work.

Are plating solutions included?
No. Plating solutions (gold, silver, copper, nickel, etc.) are not included and must be purchased separately from a plating supply store. The rectifier, alligator clip, and user manual are included.

What current setting should I use for gold plating?
The correct current density depends on your plating solution, tank size, and workpiece surface area. Consult the plating solution manufacturer's specifications for the recommended current density (typically expressed in A/dm²), then calculate the required current based on your workpiece surface area.

Can I use this for both small jewelry tanks and larger production tanks?
Yes. The 30A maximum current rating covers both small jewelry plating tanks used in repair shops and larger production tanks. Adjust the current output to match the tank size and workpiece surface area.

What does the over-current protection do?
If the output current exceeds the set limit — due to a short circuit, solution conductivity change, or other fault — the over-current protection circuit reduces or cuts the output to prevent damage to the rectifier and the workpiece.
