DC STICK OPERATION
• High voltage danger from power source! Consult a qualified electrician for proper installation
of receptacle. This cutter must be Grounded while in use to protect the operator from electrical
shock.
• Do not remove grounding prong or alter the plug in any way. Use only the supplied adapter
between the welder's power cord and the power source receptacle. Make sure the POWER
switch is OFF when connecting your plasma cutter's power cord directly to a properly grounded
120 VAC, 60 Hz, single phase, 20-amp input power supply.
1. SETTING UP THE WORK PIECE
1.1 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.
1.2 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 degrees. See following picture:
Based on different welding positions, there are different welding joints. See following images for
more information.
