The device is a component of an automatic welding system. The built-in microprocessor facilitates complete control of all welding functions. The device is suitable for the following welding procedures/functions:
mX Standard DC | Standard welding procedures without pulses. From short arc with low energy input to high power spray arc. Suitable for all base materials, cored wires, and shielding gases. |
mX Pulse DC | Pulse welding process for different penetration profiles. Standard and high-performance settings for all base materials, flux cored wires, and shielding gases. |
mX Clean (not available for iROB 301) | Less spatter in the short arc due to modified bead separation. Higher welding speed for large tolerances, flat and uniform seam geometry. |
mX Move DC | Focus on CrNi and Al Controlled heat input by pulsing at two power levels.. TIG-like seam surface. |
Penetration Control | Controlled penetration. High welding speed with reduced risk of undercuts. |
All welding parameters can be saved to the integrated job memory. In synergy mode, the welding voltage is automatically adjusted to the set welding current. The parameter setting function can be used to finely adjust the automatically determined welding voltage. Use of the Penetration Control function makes it possible to automatically adjust the wire feed speed so that the welding current remains constant even if the free welding wire end varies.
The control elements may vary depending on the product type.
