Resetting Parameters To Default Values; Mig-Mag Welding Operations - Solter aeroprocess 4200 DV Manual De Instrucciones

RESETTING PARAMETERS TO DEFAULT VALUES

All operating program data can be reset to the default value, which is useful for correcting problems caused by unin-
tentionally altered parameters.
To reset, enter the menu and select "ini". When you press the master control, you will be asked to confirm this action.
With the main control, select "YES" and all data of the current operating program will be reset.
ATTENTION
Programs stored in memory by the user will not be reset.

MIG-MAG WELDING OPERATIONS

Wire feeding system
The wire feeding system must be prepared with the suitable options for the material used. You must install the appro-
priate rollers for the material in use and set the roller pressure to minimum, so that the wire is pulled tightly, but can
slip if there is a blockage in the wire feed guide.
Follow the procedure below for set the roller pressure correctly:
1- Press the threading button until the welding wire emerges through the torch.
2- Lower the roller pressure to the minimum (position 1 of the tensor).
3- Place the torch at an angle of 45º with the nozzle about 5 cm from a wooden surface.
4- Press the threading button so that the wire emerges onto the wooden surface.
5- Increase the roller pressure until the wire stops skidding and can move forward. At that point, give one more half
turn to the slack adjuster.
6- If the wire always skids, even with the maximum pressure, this indicates that there is a problem in the wire feeding
system. You should check the wire guide (towline), brake setting, state of the contact tip and roller wear.
The torch should also be prepared with the right consumables for the material used. This includes using a specific tip
and guide for the section of the wire in use. For aluminium, Teflon or graphite guide is required. Torches of more than
three metres length are not recommended. If you want to use a longer torch, you should use a "PUSH-PULL" torch.
It's important to connect the torch firmly to the winder to avoid overheatings or brownouts.
For welding aluminium, the output guide should be removed from the SCART and torch's internal guide (teflon or gra-
phite guide), should reach the drive rollers.
Place the coil of wire in the support provided for this purpose, so that the coil rotates in a clockwise direction when in
operation. Make sure that no part protrudes from the coil of wire. Use the SOLTER 56125 adapter for 150mm diame-
ter coils. The end of the wire must be filed so that it slides correctly and does not get stuck or damage the guide. Ad-
just the brake so that the coil does not continue rotating when the motor stops. Excessive pressure from the brake
can make the drive engine skid, causing defects in the weld. This brake is located inside the wire coil holder. Finally,
screw in the bolt firmly to secure the coil to the coil holder. Pass the wire through the motor rollers so that it penetra-
tes 10cm into the torch towline and then close the roller clamps. During the welding process, the drive motor access
door and coil holder lid must remain closed.
ATTENTION
The wire feeding system components are subject to wear. For optimum welding quality, maintenance of the
wire feeding system is essential. See maintenance instructions in the Aerofeed manual.
Shielding gas
The appropriate shielding gas must be connected for each type of material. The wrong gas can cause incorrect wel-
ding or machine malfunction. It is important for the torch diffuser to be clean for optimal distribution of the shielding
gas. The equipment automatically detect if there is shelding gas, if the shelding gas in not connected, the welding
process will not start. Alarm number 11 will be displayed temporarily on the control panel.
Wire threading
Remove the contact tip of the torch to ensure smooth threading. Use the threading button on the Aerofeed control
panel to complete the process. Threading speed can be adjusted using the speed potentiometer on the Aerofeed
panel (if the remote control is activated), or with the main selector of the power unit panel (under local control).
