RAZOR MULTI 250 

OPERATING MANUAL

24. 

Turn gas bottle on, and adjust gas flow to 8-12L/min. 

26. 

Run through your preferred setup using the front panel 
of the machine, after first ensuring that you have MIG 
mode selected using the 

WELD MODE

 button.  

25. 

Connect earth clamp to your workpiece. 

27. 

Line up the torch with your workpiece, then pull the 

trigger to initiate the weld. For gas-shielded MIG, the 

push method is recommended for optimum weld 

quality. Release trigger to end the weld.
