MMA welding

− Make sure that the switch (P) 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 (P).
− Press the selector switch E until the LED F lights.
− Adjust the current based on the electrode diameter, welding position and type of joint to be made.
− Also adjust the hot-start using the knob A (recommended setting 15) and the arc-force using the knob C (recom-
mended setting 30 for basic electrodes).
Always remember to shut off the machine and remove the electrode from the clamp after welding.

TIG welding

− This welding machine is suitable for welding the following materials using the TIG procedure: stainless steel, iron,
copper.
− Make sure that the switch (P) is in position 0.
− 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.
− Connect the power connector of the TIG torch to the negative pole (-) of the welding machine.
− Connect the gas hose to the outlet of the pressure regulator, connected to an ARGON cylinder.
− Use a tungsten electrode with 2% thorium (red stripe).
− Do not touch the electrode and mass terminal simultaneously.
− Turn the machine on using the switch (P).
− Use the selector switch E to set the type of TIG welding, continuous or pulsed.
− Strike the arc by contact using a firm, rapid stroke.
Remember to shut off the machine and close the gas cylinder valve when you have finished welding.

Preparing the electrode

Grind the electrode tip so that it has vertical grooves as shown in the figure.
− To profile the tungsten, use a hard, fine-grained abrasive grinding wheel used solely for this purpose.
− Be careful with metal particle.
