I) Adjusts an overcurrent that may be inserted to aid in
striking the arc. This function is active in both MMA and TIG
modes (Art. 261).
L) Adjusts an overcurrent that makes it possible to maximize
transferring the electrode drop to the workpiece. This function
is not active in TIG welding (Art. 261).
3.2 MMA WELDING
• This welding machine is suitable for welding all types of
electrodes, with the exception of cellulosic (AWS 6010).
• Make sure that the switch (F) is in position 0, then connect
the welding cables, matching the polarity required by the
manufacturer of the electrodes you will be using.
VERY IMPORTANT: Connect the terminal of the grounding
cable to the workpiece, making sure that contact is good to
ensure smooth equipment operation and avoid voltage dips
with the workpiece.
• Do not touch the torch or electrode clamp simultaneously
with the mass terminal.
• Turn the machine on using the switch (F).
• Adjust the welding current using the knob (A), the hot start
using the knob (I), and the arc force using the knob (L).
Always remember to shut off the machine and remove
the electrode from the clamp after welding.
3.3 TIG WELDING
• This welding machine is suitable for welding the following
materials using the TIG procedure: stainless steel, iron, cop-
per.
• Make sure that the switch (F) is in position 0.

Art.257-261
• Connect the mass cable connector to the positive pole (+)
of the welding machine, and the clamp to the workpiece as
close as possible to the welding point.
• Use the torch type T150 and connect the power connector
to the negative pole (-) of the welding machine (Art. 261).
• Connect the gas hose to the outlet of the pressure regula-
tor, connected to an ARGON cylinder.
. Press the torch trigger and adjust the gas flow.
• Inside the torch is a valve that blocks the gas flow when the
trigger is released.
. Use a 2% thorium-covered tungsten electrode (red strip),
diameter 1.6 (1/16").
• Turn the machine on using the switch (F).
• Adjust the welding current using the knob (A) and the hot
start using the knob (I) (Art. 261).
• Strike the arc by contact using a firm, rapid stroke.
• Remember to shut off the machine and close the gas cylin-
der valve when you have finished welding.
Note: The machine will set itself for TIG welding only if the
required accessories are connected to the adapter H (Art.
261).
This machine is intended for use with the following accesso-
ries:
a) torch type T 150 Art. 1567-20 with gas valve and start trig
ger,
b) torch type T 150 Art. 1567-02 with gas valve, start trigger
and current setting potentiometer,
c) Art. 181 pedal with potentiometer for current adjustment,
d) Art. 1180 adapter to simultaneously attach the torch Art.
1567-20 or 1567-02 and the pedal Art. 181.
e) torch Art. 1567.01 (Art. 257).
