Start Up
Operation
• In order to assure the flow of the electric circuit you must clean the work pieces 0,78" to 1,18" around the zone where the
ground clamp will be connected and around the zone to be welded.
• Connect the ground clamp to the work piece or the work bench where the work piece is supported.
• Connect the welder to the power supply.
• Once the welder is duly installed, connected and configured, and all the safety measures are taken care of, you can start
working the welder.
• Use the welding mask.
MIG
• Select the MIG function (micro wire
screen.
• Hold the torch with your hand and point the contact
nozzle towards the slot to weld. Use a 30° angle
approximately. It should allow you to see the contact point
between the electrode and the work piece.
• Lower the welding mask.
• Make contact with the micro wire tip onto the work piece
while pressing the torch trigger (A). The current will
generate the electric arc (B) between the work piece and
E
the micro wire (C).
• With the GMAW weld, while the micro wire is fed, gas (D)
is expelled to protect the arc.
• To stop the job, release the torch trigger. Current will stop
passing, the micro wire will stop as well as the gas flow.
A
SMAW
• Select the SMAW function (covered electrode
the LCD screen.
• Aim the electrode tip towards the joint to be worked to
generate the electric arc and to start welding.
• Once the arc is lit start welding keeping always the
electrode tip at a distance of 0,078" away from the work
piece.
• When the electrode has consumed 0,39" to 0,78" from
the electrode colder, replace it with a new one to keep on
welding.
CAUTION • The electrode burns in a high
temperature. Do not try to manipulate the remains of the
electrode with your hand. Place the remains in a metal
container.

TIG
• Select the TIG function (tungsten electrode
LCD screen.
• To start the arc, place the nozzle in an angle onto the
work piece (1).
• Lift the torch but do not separate the nozzle from the
work piece to put the electrode near the work piece (2).
• When the arc is started lift the torch so that the electrode
tip stays at 0,078" from the work piece (3) and start welding.
• We recommend keeping the electrode at 90° in the
vertical while welding to guarantee the protection from the
gas.
• For this process, an AN-GRUPO1 torch
CAUTION
is required and a tank or can of protection gas not
included.
