Installation
1. Power requirement
AC single phase 220V/230V, 50/60 Hz mains supply fused with a 20 amp time delayed fuse or
circuit breaker is required.
WARNING
•
High voltage danger from power source!
Consult a qualified electrician for proper
installation of needed socket. This welder must be grounded while in use to protect the operator from
electric shock.
• Do not remove grounding prong or alter the plug in any way. Do not use any adapters between the
welder’s power cord and the power source socket. Make sure the POWER switch is in OFF position
when connecting your welder’s power cord to a properly grounded 220V/230V ac, 50/60 Hz,
single phase 20 amp mains power source.
2. Extension cord
During normal use, an extension cord should not be used. It is strongly recommended that an extension
cord should not be applied because of the voltage drop they produce. This voltage drop can affect the
performance of the welder. If you must use an extension cord it needs to be a #12 gauge cord at the
smallest. Do not use an extension cord over 7.5 m in length.
3. Setting up the work piece
3.1 Welding positions
There are two basic positions, for welding: Flat and Horizontal. Flat welding is generally easier, faster,
and allows better weld fusion. If possible, the work piece should be positioned so that the bead will run
on a flat surface.
3.2 Preparing the Joint
Before welding, ensure that the surface of workpiece is free of dirt, rust, lime scale, oil or paint.
Otherwise, it will create brittle and porous weld. If the base metal pieces to be joined are thick or heavy,
it may be necessary to bevel the edges with an angle grinder. The correct groove angle should be
around 60 degrees.
