1. Adjusting function for the welding voltage and welding current

NB 500D supply the adjusting range at MIG/MAG as following,
Welding voltage : 14V±3V~44V±3V use the voltage adjusting knob
Welding current : 20A~500A use the current adjusting knob
1.2 NB 500Dsupply the adjusting range at MMA as following,
Welding current : 10A~500A use the welding current knob on the panel.

2 .Adjusting function of the Arc thrusting
It has the important function to select the proper Arc thrusting for improvement of the welding
line ,control the welding splash and the steady Arc. Normally,.
If the thrusting is low ,the arc is soft and splash .
If the thrusting is high, the arc is strong and high splash.
Use the arc thrusting continuously by the control knob on the front panel of NB 500D.

3. Function of arc drawing back
Reduce the welding criterion at the end of welding line in order to fill the short coming of
welding end.
Change the knob on the welding gun ,you may get two kinds of welding criterions to fit for
different position and different thickness. Turn on the switch of :"Arc drawing back". the power now has
the function of Arc drawing back. The voltage adjusting is used by the current knob on the front panel.
