• To start the arch, set the nozzle making an angle onto the
work piece (
1
).
• Lift the torch, not separating it from the work piece to
approach the electrode to the work piece (
2
).
• When starting the electric arc, lift the torch so that the
electrode tip is 0,08” away from the work piece (
3
) and start
welding.
• It is advisable to keep the
electrode 90° vertical during the
welding to guarantee the protection
of the gas.
TIG Connection
• This inverter welder can also be used for TIG welding, a high-quality welding process with non-consumable tungsten electrodes
and arch protected with inert gas like argon gas o helium.
• TIG welding is ideal to weld stainless steel, iron and copper.
• With this process, a AN-SOIN-250 torch and a can of protective gas are required (not included).
• Press the lower arrow in the process selector to set the welder into the TIG mode. (Tungsten electrode).
The LED facing down will turn ON.
• The connection shall be set in direct polarity:
• Connect the clamp cable to ground the positive outlet
terminal (
+
) of the welder and the grounding clamp to
the work piece.
• Connect the torch cable (
A
) to the negative outlet
terminal (
-
) of the welder.
• Connect the torch gas input (
B
) to the output
valve of the regulator (
C
) of the protection gas.
• Turn the torch valve (
D
) to open the gas flow
until generating an approximate flow in
L/min, 6 times the diameter of the
electrode.
