PATON StandardTIG DC MMA/TIG/MIG/MAG
Caution! In the MMA welding mode, after the mains switch is switched to the "I" position,
the MMA is energized. Do not touch conductive or grounded objects such as, e.g., the
housing of the welding unit, etc. with the electrode, since the unit will perceive this condition
as a signal to start the welding process.
3.1 WELDING PROCESS CYCLE - MMA
See paragraph 6.1 for the procedure for switching the value of any function
3.2 “HOT - START” FUNCTION
Advantages:
- improved striking even when using poorly ignited electrodes;
- better penetration of the base material during striking, therefore, less lack of penetration;
- prevention of slag inclusions;
- manual setting: allows you to set the function level to the minimum value, which greatly
reduces power consumption at the initial moment of striking. This allows the source to start
at mains voltage values close to the minimum possible ones, but reduces the quality of the
moment of striking (the unit becomes similar to a transformer source, but it is the only
possible way in certain situations). You can also increase the function to the maximum value
to further improve the striking timing (when using good mains). However, do not forget that
the increased current of this function can burn through the workpiece when welding thin
metals, so we recommend reducing the "Hot start" in this case.
