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.
Electrode cable 500A / 3m, extreme power for gouging and special tasks
When the current reaches 500A, the equipment has to be of armoured class, made for the heaviest industrial tasks. In fact, this cable is a tool dedicated to air carbon arc gouging and to welding thick plate in continuous work. Of course, its heart is a massive 95 mm² cable and an armoured 600A electrode holder. Thanks to that, you get stability and safety where power matters most.

Key features and benefits, an advantage in every detail
600A holder and 95 mm² cable: a pair for special tasks
Work at 500A, and gouging above all, creates extreme temperatures and loads. That is exactly why this cable brings together two uncompromising parts. First, the massive 95 mm² cable carries the high current without trouble and dissipates heat very well. Second, the armoured 600A holder with reinforced insulation and strong jaws grips carbon and covered electrodes of the largest diameters firmly. As a result, you gain maximum safety and performance.
Remarkably low voltage drop
In demanding processes every volt counts. Thanks to the use of such a thick conductor, the voltage drop is reduced to an absolute minimum. This means that almost 100% of the power set on the machine reaches the work. In consequence, gouging is faster and more effective, and the arc is very stable and carries high energy.
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 / 3m
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): 6 m (3m electrode cable + 3m earth cable)
- Cross section (A): 95 mm²
- Resistivity of copper (ρ): ≈ 0.0175 Ω, mm²/m
Step 2: the resistance (R)
R = (ρ × L) / A = (0.0175 × 6) / 95 ≈ 0.0011 Ω
Step 3: the voltage drop (ΔU)
ΔU = I × R = 500 A × 0.0011 Ω ≈ 0.56 V
Conclusion
As you can see, a voltage drop of only 0.56 V at a current of 500A is an outstanding result. This means that practically 100% of the power of your machine is delivered to the work, which is decisive in demanding processes.
In summary, with this electrode cable you gain:
- Readiness for work at 500A, right for gouging and heavy welding.
- Maximum safety thanks to the 95 mm² cable and the armoured 600A holder.
- A very low voltage drop (0.56V), which means maximum efficiency.
- Industrial build quality, ready for years of the heaviest work.
