Setting Up The Work Piece - Klutch ST80i Owner's Manual

4. SETTING UP THE WORK PIECE

4.1 Welding positions
There are two basic positions, for welding: Flat and Horizontal. Flat welding is generally easier,
faster, and allows for better penetration. If possible, the work piece should be positioned so that the
bead will run on a flat surface.
4.2 Preparing the Joint
Before welding, the surface of work piece needs to be free of dirt, rust, scale, oil or paint or it will
create brittle and porous welds. If the base metal pieces to be joined are thick or heavy, it may be
necessary to bevel the edges with a metal grinder, the correct bevel should be around 60 degree.
See following picture:
Based on different welding position, there are different welding joint, see following images for more
information.
