Contact Tip Holder (M6)	5 pcs	142.0003 (M6)
Total Pieces	32 pcs	Complete kit for 24KD MB24 torch

You’ll see that the kit’s composition gives you many more tips than nozzles, which matches real-world wear patterns where tips wear faster. The ceramic diffusers and M6 holders are included to help with stable gas flow and secure tip attachment.

Package Breakdown

You’ll notice the kit favors contact tips numerically because those are the small consumables you’ll replace most frequently. You’ll also get multiple diffusers and holders so your full tip assembly can be renewed as needed. The conical nozzles are fewer because they tend to last longer than tips under normal use.

Part Numbers and Quantities

You’ll want to note the part numbers if you plan to reorder individual pieces later. The listed numbers correspond to the parts in the kit: contact tip 140.0051, gas nozzle 145.0080, holder 142.0003, and diffuser 012.0183. Keep that list handy for reordering the exact replacements.

Compatibility and Fit

You’ll want to confirm that this kit fits your torch before ordering. It’s specifically made for the 24KD MB24 style MIG/MAG torches, which are common on many hand-held MIG setups used with CO₂ (CO₂) or mixed shielding gases.

Torch Models Supported

You’ll typically use these parts with MB24/MB24S/24KD style torches found on many DC MIG machines and MIG welders that use M6 threaded consumables. If your torch uses a different thread or different nozzle seating, these parts may not fit correctly.

Threading and Size Details

You’ll find the contact tips use an M6 thread and the included tips are 0.8 mm in diameter for the welding wire contact point. The M6 standard threading means the tips and holders are compatible with many euro-style connections, but you should double-check your torch’s thread pitch and holder type to avoid mismatches.

Materials and Build Quality

You’ll notice the parts are made from typical consumable materials aimed at balancing conductivity, durability, and cost. Contact tips are generally brass or copper alloys for good conductivity, while diffusers use ceramic for thermal and electrical insulation.

Contact Tips: Material and Performance

You’ll get 20 M6 contact tips in 0.8 mm, which are usually made from high-conductivity copper alloy or similar materials. That helps reduce voltage drop and prevents excessive heating at the tip. You’ll also notice that the tips are bulk-packed, so you’ll want to inspect each one for burrs before use, but most will be ready to install.

Gas Nozzles/Conical Cups: Design and Durability

You’ll see two conical cup-style gas nozzles, which are shaped to stabilize shielding gas coverage and control turbulence. These nozzles are typically plated or made from brass and are built to resist moderate spatter; however, you’ll still need to clean them regularly to maintain gas flow.

Gas Diffuser Ceramic: Why Ceramic Matters

You’ll benefit from ceramic diffusers because they help direct gas evenly and insulate the contact tip electrically. The 5 ceramic diffusers included will give you replacements for when diffusers crack or become clogged. Ceramic resists heat well but can chip if handled roughly.

Performance and Welding Results

You’ll get predictable arc behavior from a fresh set of consumables when you maintain correct alignment and gas flow. Fresh contact tips and clean nozzles reduce erratic wire feeding and inconsistent arcs, which means fewer weld defects and less time spent troubleshooting.

Wire Feed and Contact Tip Life

You’ll experience smoother wire feeding with a correctly sized and undamaged 0.8 mm contact tip. The tip life depends on your welding amperage, wire type (solid vs flux-cored), and cleanliness; heavier use and more abrasive wires will shorten tip life. By keeping spare 20 tips on hand, you’ll avoid downtime when tips wear.

Shielding Gas Performance and Nozzle Influence

You’ll find coverage effectiveness improves with clean nozzles and a matching diffuser. Conical cups help shape the gas plume, which is especially helpful if you’re using the torch in tight spaces or around drafts. If gas flow is unstable, you’ll see porosity and poor bead shape, so nozzle and diffuser condition directly affect results.

Installation and Replacement Guide

You’ll be able to swap parts quickly with basic hand tools and by following a few steps to ensure safety. Replacing tips, holders, diffusers, or nozzles is routine maintenance you can do in minutes once you know the sequence.

Replacing Contact Tips

You’ll first power down and unthread the nozzle. You’ll then unscrew the worn tip from the holder and screw in the new M6 tip by hand until snug, then give a small additional quarter-turn with a suitable driver to secure it without over-tightening. You’ll want to verify the wire passes freely and is centered through the new tip before welding.

Replacing Gas Nozzle and Diffuser

You’ll remove the old nozzle by unscrewing or pulling it off (depending on design), then pull the old diffuser out. You’ll seat the new ceramic diffuser so it aligns with the internal gas channel and thread or press the new nozzle back into place. Make sure the nozzle is clean and free from spatter before reassembly for optimal gas coverage.

Contact Tip Holder Installation

You’ll replace the tip holder if it’s damaged or if the thread is worn. You’ll unscrew the old holder and replace it with the new M6 holder, ensuring it seats firmly into the torch head. You’ll then install the contact tip into the holder and confirm the assembly is straight and secure.

Maintenance and Care Tips

You’ll extend the life of your consumables by keeping them clean, checking alignment, and using the right gas and wire. Regular preventive maintenance reduces the frequency of replacements and improves weld quality.

Cleaning Nozzles and Diffusers

You’ll want to remove spatter buildup from nozzles after each session. You’ll use a nozzle brush or dedicated spatter remover and occasionally a flux remover spray for sticky residues. You’ll avoid using tools that can deform the nozzle shape, as that will alter gas flow.

Extending Tip Life: Wire Feed, Alignment, Gas Flow

You’ll get longer tip life when the wire is properly aligned and the drive rolls are correctly tensioned. You’ll also minimize tip overheating by using appropriate welding parameters and ensuring adequate shielding gas flow; blocked diffusers and nozzles create back pressure that increases tip wear.

Troubleshooting Common Issues

You’ll find most arc and feed problems traceable to worn or misaligned consumables. Rather than guessing, you’ll check tip condition, seating, and gas flow first.

Common Symptoms and What They Mean

You’ll see bird-nesting or poor feed when the contact tip bore is worn or the tip is loose. You’ll see unstable arc and porosity when gas coverage is compromised by dirty nozzles or cracked diffusers. You’ll hear a buzzing or see erratic arc when tip contact is intermittent, which usually points to a damaged tip or holder.

When to Replace Consumables

You’ll replace the contact tip when the wire starts to wobble inside the bore or when you notice excessive heating. You’ll consider new nozzles when spatter reduces gas coverage or when the nozzle opening is significantly deformed. You’ll swap diffusers if they crack or if you detect uneven gas flow that affects bead appearance.

Comparison with Other Kits

You’ll want to compare piece counts, material quality, and price when choosing a consumables kit. This RIVERWELD kit offers a high tip-to-nozzle ratio, which matches typical wear patterns, and includes ceramic diffusers that some cheaper kits omit.

Similar Kits and Alternatives

You’ll find alternatives with different tip diameters or thread types; some kits focus on flux-cored welding and provide different nozzle geometries. You’ll compare whether those kits include more nozzles or fewer tips, and whether their tips are copper, copper-plated, or made from a higher-end alloy for longer life.

Value for Money

You’ll often see good value when a kit covers the fast-wearing parts you need most, and this 32-piece kit targets that need. You’ll save time and shipping cost compared with buying parts individually, and you’ll likely pay less per tip than buying single replacements.
