Welding Plugs & Receptacles from MELTRIC

MELTRIC Switch-Rated plugs and receptacles are ideal for connecting power to welding machines and other portable equipment.

Worker safety is assured at all times because an integral switch mechanism on the receptacle safely deenergizes the plug before it can be withdrawn. Once removed, a safety shutter ensures that workers are protected from live parts.

Compliance to electrical codes and safety standards is simplified because MELTRIC Switch-Rated plugs and receptacles are UL and CSA listed as a branch circuit disconnect switch. They eliminate the need for costly mechanical interlocks or non-fused disconnect switches.

MELTRIC plugs and receptacles feature spring-loaded, silver-nickel, butt-style contacts that maintain a consistent, durable electrical connection which resists corrosion, cold welding, and overheating.

In contrast when competitors pin and sleeve devices are used: Long-term performance is a problem because brass pin and sleeve contacts are susceptible to wear, oxidation, overheating, and other factors that reduce the usable product life. As a result, facilities are often faced with product replacement costs or having to deal with dangerous, difficult-to-operate electrical connections. And safety is a concern because arc flash may result when workers neglect to deenergize before unplugging equipment.

Pin and sleeve devices are not intended for connection or disconnection of live equipment. Even if interlocked receptacles are used to prevent live disconnection, they are easily defeated when workers use extension cords.

Facilities can avoid problems associated with pin and sleeve plugs and receptacles by specifying Switch-Rated plugs and receptacles from MELTRIC.

And for retrofits of older welding receptacles, adapter plates make it easy to mount MELTRIC devices on existing back boxes.
