The companyTolerance of diameter and surface purity
According to the standard DIN EN ISO 544 the maximum tolerance of a 1.2 mm wire electrode of GMAW welding must not exceed +0.01/-0.04 mm from its nominal value.
| Diameter [mm] | Cross section [mm²] | ||
|---|---|---|---|
| Deviation | Deviation | ||
| 1,21 | 0,83% | 1,15 | 1,65% |
| 1,20 | 0,00% | 1,13 | 0,00% |
| 1,18 | -1,67% | 1,09 | -3,31% |
| 1,16 | -3,33% | 1,06 | -6,48% |
- Diamond drawn wire
- Highest precision
MIG WELD only uses drawing dies made from diamonds and this puts us in a position to keep the diameter tolerance constant within +0,0/-0,02 mm. Hence, the maximum deviation of the wire feed speed is limited to 3,31%.
Under practical conditions this means that the arc length correction doesn't require adjustment after changing to a new batch of wire. This is of utmost importance with all mechanized and robotic welding.

The surface cleaning at MIG WELD is done by a multiple, mechanical and cutting process, which is known by experts under the term “shaving”. In opposite to chemical cleaning processes this guarantees cleanest surfaces, nothing but pure metal!
