Attention!

1

.

Generally only need to adjust (10) and (11). Do not need adjust other preset parameters.

2

.

According to actual situations, sometimes can fine tune (8) and (9) to achieve the best welding effect.

Restore factory default settings

   

Press (12), LCD panel (1) shows equipment information. Then press and hold (3) and (6) at the same time for 

about 10s. Turn off the machine then turn it on.

4

.

Regular and pulse switching: The machine is preset as regular mode as 

⑤ 

in the figure. Press (13) to switch 

the mode to pulse welding indicated by a highlighted black box over the program icon as 

④ 

in the figure. Then 

(9)  is  used  to  adjust  the  pulse  frequency  instead  of  wire  feeding  speed.  Press  (13)  again,  switch  to  regular 

welding mode again.

5.Spot welding time adjustment: The defualt setting is FFF -- manual mode. It will switch to aoto mode if adjust 

(6) and (7). For example spot welding time 0.1 means 0.1s, which means that when you press and release the 

trigger  once,  the  machine  will  stop  after  feeding  wire  0.1s  (welding  only  0.1s  even  if  you  press  and  hold  the 

trigger all the time).
