5.5 Changing anti-stick time 

Anti-stick  time  is  0.3~0.5  sec.  at  the  shipment  but  it 
becomes usable to adjust time by R15 on C0056P. 
Anti-stick time is changed by welding method, wire diameter 
and current setting. 

 

 
 
 
 
 
5.6 Changing anti-stick voltage   

Anti-stick  voltage  is  15~18V  at  the  shipment  but  it 
becomes usable to adjust time by R16 on C0056P. 

Anti-stick  voltage  is  changed  by  welding  method  and  wire 
diameter.   

 
 

 
 

 
 
5.7 Changing crater repetition period   

Crater  repetition  period  is  2  sec.  at  the  shipment  but  it 
becomes usable to adjust time by R18 on C0056P. 

 

 

 

 

 

 

 
5.8 Using AC100V heater receptacle 

Extra  heating  is  necessary  to  use  gas  regulator  with  heater,  turn  S1  No.4  to  “ON”  when  use 
AC100V heater receptacle. 
Turn S1 No.4 to “OFF” when not to use heater receptacle. An energy saving function is operating. 
 
Function of S1 No.4 

ON:    MS, AC100V and fan keep “ON” 
OFF: MS, AC100V turn off 5 seconds after the welding end and fan turn off 6 seconds after the 

welding end.
