PATON ProMIG DC MMA/TIG/MIG/MAG
After releasing the button on the MIG torch, the welding process is initiated by activating
the power source and the wire feed motor. At this time, the system triggers a function
responsible for the ramp-up of the welding voltage, as well as a function increasing the wire
feed speed, aiming to reach the predetermined parameters within a specific time [t.uP].
Optionally, additional functions, such as the pulsation mode, can be enabled, all in line with
the welding cycle described in section 5.2.
After the second press of the button on the MIG torch, the system activates a function
responsible for the ramp-down of welding voltage and a function that decreases the wire
feed speed over a specified period of time [t.dn]. This process has been designed to ensure a
smooth conclusion of the device's operation and prevent sudden changes that could affect
the weld quality.
When the button is released for the second time, the function involving the application of
final post-weld gas within the welding zone [t.Po] will be initiated. This entails the controlled
closure of the gas valve with a deliberate delay, ensuring the gradual conclusion of the
welding process and the protection of the weld integrity. Upon completion of this procedure,
the device automatically switches to standby mode, indicating that it is ready for further
tasks or can remain in a sleep state without excessive energy consumption.
In the alternate mode , when using the Alt 4T button, the second cycle is skipped, meaning
the first button release is omitted. This distinguishes this mode from the standard 4T mode.
To elaborate on this concept in greater detail: in this scenario, immediately after completing
the function of pre-weld gas purging [t.Pr], the system initiates the arc ignition phase,
gradual increase of welding voltage, and wire feed speed within a predetermined time [t.dn],
without waiting for the initial button release. This essentially implies that the welding
process continues similarly to the 4T mode, albeit with certain changes in the initial
sequence.
This mode is offered by the PATON company as an additional option that can be applied
according to individual preferences.
5.3 INDUCTANCE FUNCTION
Inductance adjustment allows for precise control of the current rise rate in response to
changes in arc voltage. By increasing the inductance value, a longer and milder arc can be
achieved. This results in reduced spatter, leading to a higher weld quality and also decreasing
the need for post-weld cleaning. However, it's important to note that increasing the
inductance value will affect the droplet transfer process - welding will proceed more slowly
at higher values, and the speed of droplet transfer will decrease.
Considering the diverse needs of our users, we have designed a feature that allows everyone
to tailor the welding process to their individual requirements. For materials with a thickness
exceeding 3 mm, it is recommended to select minimum values, while for thinner elements,
maximum settings should be utilized.
