A. Weld speed is too fast. 

B. Weld speed is too slow. 

C. Arc is too long. 

D. Ideal weld. 

 

A solid weld bead requires that the electrode be moved slowly and steadily along the weld seam. 

Moving the electrode rapidly or erratically will prevent proper fusion or create a lumpy, uneven bead. 

 

ELECTRIC  SHOCK  CAN  KILL!  To  prevent  ELECTRIC  SHOCK,  do  not  perform  any  welding 

while standing, kneeling, or lying directly on the grounded workpiece. 

 

9.6 Finish the bead 

As the coating on the outside of the electrode burns off, it forms an envelope of protective gases 

around the weld. This prevents air from reaching the molten metal and creating an undesirable 

chemical reaction. The burning coating, however, forms slag. The slag formation appears as an 

accumulation of dirty metal scale on the finished weld. Slag should be removed by using a chipping 

hammer. 

 

PEENING  THE  SLAG  FROM  A  WELD  JOINT  CUASES  SMALL  CHIPS  OF  METAL  TO  FLY 

THROUGH  THE  AIR!  Metallic  chips  flying  through  the  air  can  cause  eye  injury  or  injury  to 

other  parts  of  the  head,  hands  or  exposed  portions  of  the  body.  Wear  goggles  or  safety 

glasses  with  side  shields  and  protect  the  hands  and  other  exposed  parts  of  the  body  with 

protective garments, or if possible, work with a shield between the body and the work piece. 

 

The intense heat produced at the arc sets up strains in the metal joined by welding. Peening the 

weld not only removes the scale left behind in the welding but relieves the internal strains developed 

by the heating and cooling process. 

 

MAINTENANCE

 

 

Maintain your KLUTCH ST200i. 

It is recommended that the general condition of 

KLUTCH 

ST200i 

be examined before it is used. Keep 

KLUTCH ST200i

 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.
