Avoid  starting  unintentionally.

  Be  sure  the  switch  is  in  the  off  position  when  not  in  use  and 

before plugging in. Do not carry any tool with your finger on the trigger, whether it is plugged in or 
not. 
 

Stay alert.

 Watch what you are doing. Use common sense. Do not operate any tool when tired. 

 

Check  for  damaged  parts. 

Before  using  any  tool,  any  part  that  appears  damaged  should  be 

carefully  checked  to  determine  that  it  would  operate  properly  and  perform  its  intended  function. 
Check  for  alignment  and  binding  of  moving  parts;  any  broken  parts  or  mounting  fixtures;  and  any 
other condition that may affect proper operation. Any part that is damaged should be properly repaired 
or  replaced  by  a  qualified  technician.  Do  not  use  the  tool  if  any  switch  does  not  turn  on  and  off 
properly. 
 

Guard  against  electric  shock. 

Prevent  body  contact  with  grounded  surfaces  such  as  pipes, 

radiators, ranges, and refrigerator enclosures.

 

 

Replacement parts and accessories. 

When servicing, use only identical replacement parts. Use 

of  any  other  parts  will  void  warranty.  Only  use  accessories  intended  for  use  with  this  welder. 
Approved accessories are available from 

www.uwelding.com

 

Do  not  operate  tool  if  under  the  influence  of  alcohol  or  drugs.

  Read  warning  labels  on 

prescriptions to determine if your judgment or reflexes are impaired while taking drugs. If there is any 
doubt, do not operate the welder.   
 

Maintenance. 

For  your  safety,  service  and  maintenance  should  be  performed  regularly  by  a 

qualified technician.

 

 

Use  proper  size  and  type  extension  cord.

  If  an  extension  cord  is  required,  it  must  be  of  the 

proper  size  and  type  to  supply  the  correct  current  to  the  welder  without  heating  up.  Otherwise,  the 
extension  cord  could  melt  and  catch  fire,  or  cause  electrical  damage  to  the  welder.  This  welder 
requires use of an extension cord of 20 amps minimum capability up to 30 feet, with a wire size rated 
at 12 AWG. Longer extension cords require larger size wire. If you are using the welder outdoors, use 
an extension cord rated for outdoor use, signified by “WA” on the jacket. Performance of this welder 
may vary depending on condition in local line voltage. Extension cord usage may also affect welder 
performance. 
 

 

The  warnings,  cautions  and  instructions  discussed  in  this  instruction  manual  cannot  cover  all 
possible conditions and situations that may occur. It must be understood, by the operator, that 
common  sense  and  caution  are  factors,  which  cannot  be  built  into  this  product,  but  must  be 
supplied by the operator.
