Warning: 

Never connect live or neutral wires to the earth terminal of the 

plug.  Only  fit  an  approved  plug  with  the  correct rated  fuse.  If  in  doubt 

consult a qualified electrician.

 

Note: 

Always make sure the mains supply is of the correct voltage and the 

correct  fuse  protection  is  used.  In  the  event  of  replacing  the  fuse  always 

replace the fuse with the same value as the original.

 

Note: 

If  an  extension  lead  is  required  in  order  to reach  the  mains  supply; 

ensure that this too is rated for the correct voltage and fuse rating.

Guarantee: 

 

This SIP inverter welder is covered by a 24 month parts and labour warranty covering 

failure due to manufacturers defects. This does not cover failure due to misuse or op-

erating the welder outside the scope of this manual - any claims deemed to be out-

side the scope of the warranty may be subject to charges Including, but not limited to 

parts, labour and carriage costs.  

 

Failure  to  regularly  clean  your  welder  will  shorten  its  working  life  and  reduce  perfor-

mance. The warranty does not cover consumable items such as collets, ceramics & 

clamps etc.

  OPERATING INSTRUCTIONS….cont

 

Place the earth clamp onto a cleaned area of the workpiece. 
Fit the ground tungsten into the TIG torch head. 
Connect the regulator (not supplied) onto the gas bottle. 
Connect the gas pipe from the rear of the welder onto the regulator. 
Turn the regulator on. 
Connect the welder to the electrical supply but do not switch on. 

   WELDING 

Caution: 

Ensure all protective equipment is worn and bystanders are not in 

the vicinity. 

Switch the welder on.

 

Set the required welding parameters as explained on page 16, 17 & 18.

 

Place a face mask / helmet over your face (not supplied).  
Initiate the arc; How the arc is initiated will depend on which setting have been 

used when setting the welding parameters.

 

Once all work has been done, switch the machine and the gas off.

 

   ARC WELDING 

To connect  the earth lead simply line up the tab on  the dinse connector with the 

cut out on the negative dinse socket and turn clockwise to secure. 
Connect  the  electrode  holder  lead  in  the  same  way,  but  connect  to  the  positive 

socket.
