AC/DC Inverter TIG/MMA Welding Machine With Pulse - YTIG-400PR

Exact digital current and voltage preset, it makes the machine easy operated.
Advanced IGBT inverter technology, high working frequency, high working efficiency and energy saving.
Independently adjustable of pre-flow and post-flow, easy operation.
Independently adjustable of upslope and downslope, effectively control welding process.
High frequency and low frequency of pulse frequency, which is suitable for manual and automatic welding.
With good protection of under voltage, over voltage and over current, it makes the machine safe and reliable.

2 to 10-pulses-per-second range, the arc is considered “soft”.
This is ideal for a broad bead, and deep penetration is not the goal.
An outside corner joint is one example where this may be desirable, Or a final “wash” pass that caps off multiple root passes.
This low frequency may also be beneficial when making a pass over a weld that has an uneven bead profile.
Try to avoid Pulsing between 10 and 30 cycles per second as it may not give a proper penetration.
Preferably weld above 50 cycles per second It makes a good choice to make the arc “stiffer” when TIG welding
This can help drive the penetration deeper into a narrow joint.
This may also allow faster travel speeds and give the arc better directional control.
