8.6 SPOT WELDING INSTRUCTIONS 

1.  Select  the  wire  diameter  and  heat  setting  recommended  above  for  the  method  of  spot welding 

you intend to use. 

2. Tune in the wire speed as if you were going to make a continuous weld. 

3. Hold the nozzle piece completely perpendicular to and about 1/4 inch off the work piece. 

4. Pull the trigger on the torch and release it when it appears that the desired penetration has been 

achieved. 

5. Make practice spot welds on scrap metal, varying the length of time you hold the trigger, until a 

desired spot weld is made. 

6. Make spot welds on the actual work piece at desired locations. 

 

 

 

MAINTENANCE

 

 

Maintain your FC125X. 

It is recommended that the general condition of any 

FC125X 

be 

examined before it is used. Keep your 

FC125X

 in good repair by adopting a program of 

conscientious repair and maintenance. Have necessary repairs made by qualified service 

personnel.

 

 

Periodically clean dust, dirt, grease, etc. from your welder. 

 

 

Every six months, or as necessary, remove the cover panel from the welder and air-blow any 

dust and dirt that may have accumulated inside the welder.

 

 

Replace power cord, ground cable, ground clamp, or electrode assembly when damaged or 

worn.
