• 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-SI-12/16/20 torch and a can of protective gas are required (not included).
• Press the process selector to make the welder into the TIG mode. (Tungsten electrode).
The upper LED of the selector will light up.
• 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 torch valve (
D
) to open gas flow. Turn
the knob ( E ) of the regulator to adjust the
gas flow until obtaining an approximate
flow in L / min of 6 times the diameter
of the electrode.

• 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.
