Electrode Welding - GYS MULTIWELD FV 220M Bedienungsanleitung

WELDING CURRENT SETTINGS
The following settings concern the current range that may be used depending on the electrode's type and diameter. These ranges are
quite large as they depend on the application and the welding position.

ELECTRODE WELDING

• The reverse polarity cable must be disconnected in MMA (stick welding) mode in order to connect the electrode holder and earth
clamp. Connect the electrode holder and earth clamp as indicated on the electrode packaging.
• Respect the basic rules of welding.
• This device has 1 feature specific to Inverter machines :
- Anti-Sticking: Enables easy removal of the electrode from the metal. The anti-sticking feature, after its start, requires approxima-
tely a 3 seconds delay before resuming normal welding operations.
PROTECTION AND RECOMMENDATIONS
1 - Overheating:
This unit is equipped with a ventilation system regulated by the temperature of the device. When the unit switches to thermal
protection, it no longer delivers any current. The orange LED (fig. VI-1) lights up until the temperature of the unit has returned to
normal.
• Ensure the ventilation holes of the unit are not blocked to allow adequate air circulation.
• Leave the unit switched on after welding and during thermal protection to allow cooling.
2 - Overcurrent:
This unit is equipped with a primary current measurement. In case of overcurrent, the orange LED (fig. VI-1) lights up. In this case
the unit must be switched off and restarted.
3 - P400 (FV 220M only) :
This unit is equipped with primary overvoltage protection. In this case, the orange LED (fig. VI-1) will flash once per second.
4 - Observations:
• Respect the basic rules of welding.
• Ensure that there is sufficient ventilation.
• Do not work on a damp surface. To prevent gas leaks, use the clamps supplied in the accessory box.
- Make sure that the gas cylinder is held in place with the fixing collar, see fig. V.
- Set the gas flow rate by adjusting the control dial on the pressure regulator.

REMEDIES
Wait for the indicator to turn off before
resuming welding operations.
Observe the operating factor and ensure
good ventilation
Have your electrical installation checked
by a qualified person.
Clean out the contact batch or change it
and replace the anti-adherence product.
• Control the roller pressure or replace it.
• Wire diameter non-compatible with
roller.
• Covering wire guide in the torch
non-compatible.
