c. Hold the nozzle piece completely perpendicular to and about 1/4 inch off the work
piece.
d. Pull the trigger on the torch and release it when it appears that the desired
penetration has been achieved.
e. Make practice spot welds on scrap metal, varying the length of time you hold the
trigger, until a desired spot weld is made.
f. Make spot welds on the actual work piece at desired locations.
DC STICK OPERATION
WARNING
High voltage danger from power source!
Consult a qualified electrician for proper installation of receptacle at the power source. This welder
must be grounded while in use to protect the operator from electrical shock. If you are not sure if
your outlet is properly grounded, have it checked by a qualified electrician. Do not cut off the
grounding prong or alter the plug in any way and do not use any adapter, other than the supplied
adapter, between the welder's power cord and the power source receptacle. Make sure the power
switch is OFF then connect your welder's power cord to a properly grounded 230 VAC (220V -
240V), 60 HZ, single phase, 50 amp power source. If operating on 120V, attach the 120V Adapter
cord to the unit power cord and then connect the assembly to a properly grounded 120 VAC
(110V-130V), 60 Hz, single phase, 25 amp power source.
1. SETTING UP THE WORK PIECE
a. 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.
b. 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 the following
illustration:
Based on different welding positions, there are different welding joints. See the following illustration for
more information.
