10-Pack M8×30 MIG Contact Tips for 36KD & 501D Welding Torches
10-Pack M8×30 MIG Contact Tips for 36KD & 501D Welding Torches
10-Pack MIG Welding Contact Tips – M8×30 | CuCrZr & E-Cu | 36KD / 501D Torch Compatible
Keep your MIG welding torch performing at its peak with this 10-piece set of premium contact tips. Engineered for precision fit and extended service life, these tips are manufactured from either high-purity Electrolytic Copper (E-Cu 99.90%) or CuCrZr alloy — materials chosen for their outstanding electrical conductivity, heat resistance, and durability under continuous welding cycles. Made in Mainland China.

Why Choose These Contact Tips?
- Precision-machined fit — tight dimensional tolerances ensure secure, consistent wire-to-tip contact every pass
- Excellent heat & corrosion resistance — CuCrZr alloy maintains hardness at elevated temperatures, minimising premature wear
- Smooth bore finish — reduced burrs and rough selvedge for smooth wire feed and stable arc performance
- Long service life — high-quality copper alloy construction reduces replacement frequency and downtime
- Value pack — 10 tips per order means you always have spares on hand for uninterrupted production
Tips to Maximise Consumable Life
Always operate within the rated current and duty cycle limits (340 A CO2 / 300 A M21, 60% duty cycle). Ensure your wire feeder is properly calibrated to avoid excessive friction wear. Inspect and replace contact tips at the first sign of enlargement or wear in the bore to maintain arc quality.

Frequently Asked Questions
Q: Which welding torches are these M8×30 contact tips compatible with?
A: These contact tips are designed for Binzel-style 36KD Series, MB36, MB501, and 501D MIG/CO2 welding torches with an M8 threaded connection. Always verify your torch model and thread size before ordering to ensure a proper fit.
Q: What is the difference between E-Cu and CuCrZr contact tips?
A: E-Cu (Electrolytic Copper, 99.90% purity) offers excellent electrical conductivity, making it ideal for standard MIG welding applications. CuCrZr (copper-chromium-zirconium alloy) provides superior heat resistance and hardness at high temperatures, making it better suited for high-duty-cycle or high-amperage welding where tip longevity is a priority.
Q: What wire diameters are compatible with these contact tips?
A: These M8×30 MIG contact tips support welding wire sizes from 0.8 mm to 1.6 mm. Ensure you match the bore diameter of the tip to your specific wire size for optimal arc stability and wire feed performance.
Q: How many contact tips are included in the pack?
A: Each order includes 10 contact tips, giving you a ready supply of replacements to minimise downtime during extended welding jobs or production runs.
