Tig Welding - Elettro CF COMBO HI-MIG 2010 Manual De Instrucciones

5.2 MIG WELDING WITHOUT GAS
The actions to prepare the welding machine for work are the
same as those described previously, but for this type of
welding proceed as follows:
Mount a coil of flux-cored wire for welding without gas.
Connect the power terminal of the torch coming out from
fairlead E to the negative pole socket G.
Connect the earth cable to the socket F and the earth clamp to
the workpiece.
Select the program suited for flux-cored wire. The program is
available only in MIG SHORT SYNERGIC and MIG MANUAL
processes.
5.3 WELDING WITH COATED ELECTRODES (MMA).
Before welding it is recommended to remove the MIG torch
and mount the electrode holder.
The electrode holder must (save for different indication by the
producer of the electrodes) be connected to the socket F
(positive polarity), and the earth cable to the negative polarity,
socket G.
VERY IMPORTANT: Connect the terminal of the earth cable
to the workpiece, making sure that contact is good to ensure
smooth equipment operation and avoid voltage dips with the
workpiece.
Turn on the welding machine.
To choose this process, just select it with the knob B and
press the latter.
From the process, using the knob B, it is possible to select
and set (with the knob C) the following functions:
- H. Start Time
- H. Start Curr.
- A. Force Curr.
- Factory
- Password
Keep the knob B pressed to go back to the previous page
(PROCESS PARAMETERS).
To go back to the main menu, press the knob B again for at
least 2 sec.
Do not touch the electrode clamp and the earth clamp
simultaneously.
Always remember to shut off the machine and remove the
electrode from the clamp after welding.

5.4 TIG WELDING

Before welding it is recommended to remove the MIG torch
and mount the TIG torch.
Connect the power terminal of the torch coming out from
fairlead E to the negative pole socket G.
Connect the earth cable connector to the positive pole socket
F, and the earth clamp to the workpiece as close as possible
to the welding point.
Connect the gas hose to the outlet of the pressure regulator of
an ARGON cylinder.
Use a 2% thorium-covered tungsten electrode (red strip),
diameter 1.6 ( 1/16" ).
Turn on the machine using the switch I.
To choose this process, just select it with the knob B and
press the latter.
From the process, using the knob B, it is possible to select
and set (with the knob C) the following functions:
- Start Mode
- Slope Up
- Slope Down
- Pulse
- Spot
- Pre Gas
- Post Gas
- Factory
- Password
Keep the knob B pressed to go back to the previous page
(PROCESS PARAMETERS).
To go back to the main menu, press the knob B again for at
least 2 sec.
Strike the arc by contact using a firm, rapid stroke.
Always remember to shut off the machine and close the
gas cylinder valve when you have finished welding.
6 MAINTENANCE
Periodically make sure that the welding machine and all
connections are in good condition to ensure operator safety.
After making a repair, be careful to arrange the wiring in such
a way that the parts connected to the power supply are safely
insulated from the parts connected to the welding circuit.
Do not allow wires to come into contact with moving parts or
those that heat up during operation.
Mount the clamps as on the original machine to prevent, if a
conductor accidentally breaks or becomes disconnected, a
connection from occurring between power supply and the
welding circuits.
