Solder: What You Need to Know

Solder products, also referred to as soldering materials or bonding agents, are essential for creating strong, conductive joints in electrical, plumbing, and metalwork applications. This collection includes flux pens, solder wires, pastes, and kits in both lead-free and silver-safe formulas. Options range in size from 0.25 lb. spools to 1 lb. solid cores, with refillable pens and tip-safe pastes for precise application.

Type:

  • Flux Pen: Refillable flux pens are used to apply a controlled amount of flux directly to solder points. Ideal for electronics and fine-detail work, they ensure clean joins without excess residue.
  • Polishing Paste: Used for tip maintenance and surface preparation, polishing paste extends the life of soldering tools and improves performance. It’s effective for removing oxidation and buildup.
  • Solder: This general label covers both solid and rosin-core solder types used in standard bonding jobs. Suitable for electrical wiring, pipe sealing, and repair work.
  • Solder Flux Paste: Flux paste cleans and preps metal surfaces to enhance solder flow and adhesion. Available in multiple sizes and styles, including lead-free and tinning formulations.
  • Solder Wire: Coiled wire solder in 0.25 lb. to 8 oz. sizes offers consistent feed and melt performance. Used in both residential and industrial settings, including circuit boards and metal seams.
  • Soldering Kit: All-in-one kits include essential tools and materials for basic soldering work. Designed for DIY users or light-duty shop applications.

Solder FAQ

What types of solder are available in Los Angeles?

The types of solder available in Los Angeles include leaded solder wire, lead-free solder wire, rosin-core solder, flux paste, flux pens, and complete soldering kits. These products cover a range of applications, from electronics repair to plumbing work. Supply Ontime delivers solder and accessories across LA, with both small-quantity and bulk-order options available.

Can solder be delivered the same day in Los Angeles, and does delivery cover all areas of the county?

Yes, solder can be delivered the same day in Los Angeles, often within four hours when in stock, or by scheduling a two-hour delivery window. Supply Ontime serves all of Los Angeles County—including downtown LA, Pasadena, Long Beach, and surrounding neighborhoods—with delivery options that include Truck Bed Delivery, Curbside Delivery, and White Gloves Delivery. Whether it’s a single spool for a quick repair or bulk shipments for ongoing contractor work, Supply Ontime ensures reliable supply drops to keep projects running smoothly.

What is the difference between leaded and lead-free solder?

The difference between leaded and lead-free solder is in their melting temperature and safety profile. Leaded solder melts at lower temperatures, making it easier to handle and producing smooth joints. Lead-free solder is safer for health and required for compliance with environmental standards such as RoHS. In Los Angeles, contractors often choose lead-free for compliance and safety, while leaded solder is still used for repairs on older systems.
