Spawlab.pl
We are the manufacturer, a guarantee of the highest quality
We offer professional welding cables from our own production. For that reason, when you buy at Spawlab.pl you have full certainty that every part, from the cable to the holder, has been selected with care. What is more, everything is assembled with attention to the smallest detail. As a result, we guarantee quality without compromise and full technical support.
The ultimate electrode cable 500A / 10m, when there is no room for compromise
This is the peak of the technology among welding cables, made for the hardest tasks in shipyards, mines and on large building sites. In fact, it puts together the extreme power of 500A and a reach of 10 metres. Of course, it is based on the thickest cable in our offer, 120 mm², and an armoured 600A electrode holder. That is exactly why it is the only choice when full power is needed at maximum distance.

Key features and benefits, an advantage in every detail
Flagship 120 mm² cable: conductivity without equal over distance
This is the thickest and the strongest cable in our offer. Namely, the 120 mm² cross section of pure copper was chosen to meet a double task: an enormous current of 500A and a long distance of 10 metres. In practice this means that its ability to dissipate heat and its low resistance are decisive for stable work. Thanks to that, you can carry out heavy welding and gouging far from the power source without worrying about a loss of power.
600A holder: made for extreme power
Work at 500A, and gouging above all, creates extreme temperatures and loads. That is exactly why we fitted this cable with a top class 600A holder. First of all, its massive, heat resistant body and powerful jaws grip carbon and covered electrodes of the largest diameters firmly. As a result, you gain maximum safety and performance in the hardest conditions.
Armoured hydraulic connection
The quality of a cable is defined by its weakest point. For this reason, we join the cable to the plug by hydraulic crimping. In the end, this creates a monolithic connection, mechanically very strong and with excellent conductivity. So you can be sure that this part will never let you down, even in the heaviest work.
Confirmed quality: the calculation for 500A / 10m
We do not ask you to take our word for it. Instead, we show a transparent calculation that proves the class of this product.
Step 1: the input data
- Welding current (I): 500 A
- Total circuit length (L): 20 m (10m electrode cable + 10m earth cable)
- Cross section (A): 120 mm²
- Resistivity of copper (ρ): ≈ 0.0175 Ω, mm²/m
Step 2: the resistance (R)
R = (ρ × L) / A = (0.0175 × 20) / 120 ≈ 0.0029 Ω
Step 3: the voltage drop (ΔU)
ΔU = I × R = 500 A × 0.0029 Ω ≈ 1.46 V
Conclusion
As you can see, the result of 1.46 V proves that even with an extreme combination of power and distance the voltage losses stay under full control. This means that the cable was designed without any compromise.
In summary, with this electrode cable you gain:
- A maximum reach of 10 metres at a powerful current of 500A.
- The highest performance thanks to the powerful 120 mm² cable that keeps losses down.
- Full certainty of contact, given by the top class 600A electrode holder.
- Build quality without compromise, ready for years of the heaviest work.
