The inverter welding machine is equipped with two cables. One of them supplies current to the electrode, and the other (mass) is connected to the part being welded.
To get a strong and durable seam, a powerful and serviceable device is not enough. High-quality wires are also needed for a welding inverter of a suitable cross-section, type and length.
Copper from the available metals serves as the best conductor. Combined with its flexibility, this makes it an ideal material for making the basis of welding wire - conductive cores.
With household and semi-professional class inverters, the most common in home workshops, single-core wires of the KG brand are mainly used.
Most of the inverter wires are single-core.
One wire connects the terminals of the device to the electrode holder, the other to the mass clamp on the workpiece.
In order to connect portable inverters operating from a 220V network, light and flexible wires with a cross section of 16 mm2 are used.
Increasing the length, you need to understand that the longer the cable for connecting the welding inverter, the greater the loss and lower the current.
Any welding machine cable must meet four requirements:
1) Conduct current to the surfaces to be welded with minimal losses (for this it is made either entirely of copper or based on copper. In this case, aluminum wire is added to it)
2) Be of the required length, thickness and weight (these requirements ensure the possibility of convenient operation without unnecessary movement of the device itself and minimal heating of the cable itself when a high frequency and strength current passes through it)
3) Reliably isolate the conductive part from contact with the environment (here we are talking not only about obvious moisture, but also about metal surfaces on which welding work is often carried out)
4) Have high wear resistance (for an inverter welding machine, it must minimally change its properties under the influence of high or low temperatures, chemical reagents, mechanical stress).
