Welding and Soldering Tools and Supplies

Soldering or welding? Decide by the work

Soldering joins parts with a filler that melts below the parts themselves, which is why an iron of roughly 15 to 90 W handles electronics, jewelry and small repairs. Welding melts the base metals together and needs a torch or machine far beyond that power range. Pick the process by the work: fine electronics want a controlled low-power iron and rosin-core solder, while repairing steel frames calls for welding gear. Lead-free solder melts hotter than leaded and needs an iron that holds its heat. Start with Soldering Irons & Stations or Welding Equipment & Positioners.

Why consumables rarely cross between torches and irons

Torch and iron parts are rarely universal. Nozzles, contact tips, swirl rings and electrodes belong to a particular torch or plasma-cutter series, so match the part number or the model named in the listing. For wire-fed welding, the wire diameter must match the contact tip and drive roll, and the wire type must suit the metal: mild steel, stainless or aluminum. Soldering tips come in shapes and series for specific irons. Welding protection should carry a shade number for your process, and gloves and sleeves should be rated for heat and spatter.

Questions about Welding and Soldering Tools and Supplies

What wattage soldering iron do I need?

For circuit boards, an iron of roughly 25 to 60 W with temperature control is typical. Heavier wires and large connectors draw heat away, so they need more power or a bigger tip. A weak iron on a heavy joint heats slowly and makes poor joints.

Does leaded or lead-free solder matter?

Lead-free solder melts at a higher temperature and flows less readily, so it needs better heat control. Leaded solder is easier to work but is restricted in many electronics products and regions. Use electronics-grade rosin-core solder, never plumbing acid flux, on circuit boards.

Can MIG welding wire go in any machine?

No. The wire diameter must match the machine's contact tip and drive roll, and the wire type must suit the metal and shielding gas. Spool size matters too, since small machines take small spools. The manual lists the supported wire sizes and types.
