OPTIONAL FLOWMETER KIT
The flow meter kit (ref. 073395) allows for precise adjustment and control of the gas flow from the torch,
when connected to a gas supply. The gas pressure in the system must be stable and between 2 and 7
bar. The flow rate can be set between 3 and 30 l/min.

DEFECTS: CAUSES & SOLUTIONS
SYMPTOMS
POSSIBLE CAUSES
SOLUTIONS
The flow rate of the welding wire is not
constant.
Clogs blocking the opening.
Clean the contact tube or replace it with non-
stick material.
The wire is slipping on the rollers.
Reapply the non-stick product.
One of the rollers is spinning.
Check the tightness of the roller screw.
The torch cable is twisted.
The torch cable should be as straight as
possible.
The unwinding mechanism is not working.
The spool’s brake or roller is too tight.
Loosen the brake and rollers.
Incorrect unwinding of the wire.
Dirty or damaged wire guide.
Clean or replace.
Roller pin key is missing.
Reposition the pin in its slot.
Spool’s brake is too tight.
Release the brake.
No current or wrong welding current.
Incorrect mains outlet connection.
Check the plug connection and verify that the
plug is connected to the power supply.
Poor earth connection.
Check the earthing cable (its connection and
the condition of the clamp).
No power.
Check the torch trigger.
The wire jams after passing through the
rollers.
Crushed wire guide sheath.
Check the wire-guide sheath and body of the
torch..
Wire blockage in the torch.
Replace or clean.
No capillary tube.
Check that the capillary tube is present.
Wire speed too high.
Reduce the wire speed.
The weld bead is porous.
The gas flow is insufficient.
Adjustment range from 15 to 20 L / min.
Clean the base metal.
Gas cylinder empty.
Replace it.
Unsatisfactory gas quality.
Replace it.
Air circulation or wind influence.
Avoid draughts and protect the welding area.
Gas nozzle is too clogged.
Clean or replace the gas nozzle.
Bad wire quality.
Use a wire suitable for MIG/MAG welding.
Condition of the welding surface is too poor
(rusted, etc.).
Clean the workpiece before welding.
The gas is not connected.
Check that the gas is connected to the power
source’s inlet.
