Operation
• To assure the flowing of the electric circuit clean 0.7" to
1.2" around the zone where the grounding clamp will be
connected and around the zone to be welded to the work
pieces.
• Connect the grounding clamp to the work piece or to the
work table where the work piece will be supported.
• Connect the welder to the power supply.
• Once the welder is properly installed, connected and set
up and all the safety measures have been taken you may
start the welding job.
• Wear the welders' helmet to start welding.
• Hold the torch with your hand and point the contact
nozzle towards the slot to be welded. Use a 30° angle
approximately to be able to see the contact point between
the electrode and the work piece.
• Put the welder's helmet down.
• Make contact with the micro wire tip onto the work piece
while pressing the torch trigger. The current will generate
the electric arc (E) between the work piece and the micro
wire (F).
• With the FCAW soldering, while the micro wire is fed, the
gas (G) is released to protect the arc.
• To stop the job, release the torch trigger. The current will
stop passing, the micro wire will stop as well as the gas
flow.
Basic Weld Joint Types
1. Between thick sheets with a space between the joint to weld requiring more supply of material into the joint. Making a
circular movement with the nozzle is recommended.
2. Between thin sheets with no space between the joint to weld. A lineal and continuous movement with the nozzle is
recommended to prevent warping the material.
3. Between thin overlapping sheets with previously drilled orifices.

Start Up
Overload Protection
• The welder is built with a thermal protection to guard
against overload. When an overload strikes, the welder will
automatically turn off and the overload light (H) will light
up. Allow the unit to cool down. The thermal protector will
restart the unit when the temperature is back to safe limits.
