EASY Series 5m 500A: Mobility in the Service of Output
The SpawLab EASY series earth cable with a 70 mm2 cross section is a professional solution designed for intensive assembly work where very high welding currents are needed from time to time. The engineering of the EASY series concentrates on delivering a maximum output of 500A in a light and flexible form, achieved by tuning the copper density for intermittent duty. Over a length of 5 metres the Delta U voltage drop is only 1.88V, which preserves the dynamics of the power source and gives steady arc striking in typical workshop conditions. This accessory protects the inverter section of your welder against thermal overload and keeps the machine fully covered as long as the 20% duty cycle is respected.
Analysis of Energy Losses and Voltage Drops (500A EASY 5m)
The analysis below shows the calculated Delta U voltage drops for the complete working circuit at 500A with a SpawLab EASY 5m earth cable of 70 mm2 cross section.
| Welding Process | Accessory Configuration | Delta U Voltage Drop | Operating Characteristics |
|---|---|---|---|
| MIG/MAG | Earth 5m (70 mm2) + Torch 5m (50 mm2) | 1.88 V | Standard heavy welding; intermittent duty. |
| TIG | Earth 5m (70 mm2) + Torch 8m (40 mm2) | 2.98 V | A steady power source is required; high torch load. |
| MMA | Earth 5m (70 mm2) + Electrode holder 5m (70 mm2) | 0.78 V | Ideal balance for tacking structures. |
Who is this equipment for?
The SpawLab EASY 5m 500A cable is aimed at fabrication shops, assembly companies and hobby users who expect professional transfer quality when welding parts with large cross sections. It is a sound choice for assembly work where light accessories matter and currents of around 500 Amps are needed only for short periods. Because of the character of the EASY series, this accessory works best in tack and move tasks and on short welds, where the duty cycle of the machine does not call for a continuous linear load. It is a solution for those who value an economical balance between price and what electrolytic copper can really do.
Detailed Analysis of Technology and Features
Copper Density of 70 mm2 in the EASY Series
Using a 70 mm2 cross section at 500A over a run of 5 metres is a precise engineering choice for the EASY series, meant to keep the accessories light without a sharp rise in resistance. The physics of the welding process in this variant assumes that the mass of copper is enough to carry heat away effectively at a 20% duty cycle, which prevents thermal degradation of the insulation. Thanks to high-purity electrolytic copper, electrons flow without a bottleneck, which is decisive for arc stability in pulsed processes. Such a cross section also keeps the cable highly flexible, which makes work in awkward positions on a building site or in tight workshop spaces much easier. It is an optimal support solution for mid-range inverter machines that do not require a continuous industrial load.
H01N2-D Chloroprene Insulation
The H01N2-D insulating sheath made of chloroprene rubber offers the highest resistance to the mechanical and chemical damage met in a harsh welding environment. This material resists oils, greases and direct contact with hot welding spatter, which gives the cable a long life. The physical properties of chloroprene stop the insulation from turning brittle under UV radiation and ozone, which is decisive for keeping the welder electronics protected against accidental short circuits to the structure. The outer jacket stays flexible even at sub-zero temperatures, which allows trouble-free assembly work in the field. Choosing this class of insulation is a deliberate decision by the manufacturer to secure operator safety and steady electrical parameters throughout the service life.
Brass Spring Clamp 600A
The EASY series cable is fitted with a solid earth clamp made from cast brass, which sharply raises the point conductivity at the contact with the welded material. Brass has far better thermal properties than copper-plated steel, which removes the risk of the earth point overheating during short loads at 500A. A strong spring with a high clamping force secures a reliable mechanical connection, which is needed to avoid stray arcing that damages the surface of the part and destabilises the arc. The cable is joined to the clamp through a thick-walled copper ferrule, which stops the copper strands from working loose and keeps energy flowing steadily without losses. A solid earth contact is the foundation of safety for the IGBT section inside the machine and prevents failures caused by sudden resistance jumps in the secondary circuit.
The Logic of Intermittent Duty (EASY Standard)
The EASY series was designed around a 20% duty cycle, which means that at the full current of 500A the welding time is a maximum of 2 minutes in every 10 minutes of the cycle. That behaviour suits tacking of structures, spot assembly and short welds made in fabrication shops. Optimising the cycle allows a lighter 70 mm2 cross section, which lowers the purchase cost while keeping full function at high amperage. Keeping to the recommended welding time makes sure the cable does not overheat, which is decisive for retaining full technical support from the manufacturer and for the life of the accessories. Choosing the EASY series is a deliberate decision to match the capacity of the accessories to the real character of assembly work, where mobility and speed come before continuous production.

Technical FAQ
Is this cable suitable for continuous welding?
No. The EASY series with a 70 mm2 cross section at 500A is intended for intermittent duty at a 20% cycle. For production and continuous welding at this amperage, choose the PRO series with a 95 mm2 cross section.
How does a brass clamp differ from a steel one?
Brass has far higher electrical conductivity and gives off heat faster, which removes the risk of melting the material at high currents and keeps the arc steadier.
