PREPARE TO WELD

Always wear protective clothing, gloves, face and eye shields suitable for welding. It is
NOTE!
recommended that you make practice welds before you commence welding your main work
piece. If when igniting the arc or during welding, the electrode sticks or freezes to the work piece,
note that it will quickly heat up, and may start to glow red hot. To release the electrode, twist the
electrode holder away from the work piece and start again. If this fails, switch of the machine at the
main switch and then release the electrode after it has cooled down. Note: the electrode and work
piece will be very hot.
You can start welding after you have made the necessary preparation described throughout
these instructions.
In addition to the welding machine, welding outcome is influenced by the work piece type,
welding position and the welding environment. Therefore, recommendations in this manual
must be followed.
During welding, an electric current is flowing through the cable, clamp and electrode to the
workpiece.
The earth return cable attached to the workpiece guides the current back to the machine,
forming the closed welding circuit. Unrestricted current flow is only possible when the earth
return clamp is properly attached to the workpiece and the fixing point of the clamp is clean,
free from paint and rust free.
