Problem
The power source is
interrupted.
There is no welding
current.
The micro wire feed
mechanism is no
operating and the
energy indicator light is
ON.
The micro wire is not
feed despite the spool
is rotating.
The micro wire is fed
unevenly.
The arc is unstable.
Pores are generated in
the weld.
The electrode gets
stuck to the nozzle tip.
The weld pearl is
irregular.
18 ENGLISH
Cause
• The weld pearl is irregular.
• Blown rectifier.
• Wrong connection of the clamp with the work
piece.
• The ground line is broken.
• The torch line is broken.
• The micro wire feed mechanism is damaged.
• The pressure rod is not adjusted correctly.
• There is residue accumulated in the torch
internal covering.
• Nozzle and / or contact are dirty or defective.
• The micro wire is out of shape.
• Accumulation of residues in the internal
covering of the torch.
• Nozzle tip and / or contact nozzle dirty or
defective.
• The feeding rod notch is dirty.
• The feeding rod notch is damaged.
• The pressure rod is not well adjusted.
• The configuration of controls and connections
in the control panel is incorrect.
• Impurities in the weld area.
• Worn or defective nozzle.
• There is no gas flow.
• The nozzle tip is clogged.
• There are air gusts that dissipate the gas.
• Impurities in the welding area.
• The torch is too far away or the work angle is
wrong.
• Gas leak.
• Defective electro valve.
• Worn or defective nozzle tip.
• The micro wire is malformed.
• The micro wire speed is too slow.
• The torch is in an incorrect working position.
• The micro wire is stuck to the welding point.

Troubleshooting

Solution
• The energy is restarted automatically when the
unit gets to an adequate temperature,
approximately after 15 minutes.
• Go to a
Service Center.
• Clean and polish the contact surface and the
area around the weld.
• Replace the ground line.
• Replace the torch.
• Go to a
Service Center.
• Adjust the rod pressure.
• Clean the covering with compressed air (see
page 17).
• Clean or replace if necessary.
• Adjust the pressure in the feed rod.
• Clean the covering with compressed air, see
page 17.
• Clean or replace if necessary.
• Clean the feeding rod.
• Replace the feeding rod.
• Adjust the rod pressure.
• Check and correct the configuration.
• Clean and polish the work pieces.
• Replace the nozzle.
• Open the gas cylinder, regulate the gas valve.
• Clean or replace if necessary.
• Set a screen in the work area or increase the
gas flow.
• Clean and polish the work pieces.
• Correct the distance between the nozzle and
the work piece (from 0.31" to 0.39").
• Check all the gas connections. Tighten all the
joints.
• Go to a
Service Center for cleaning or replacement.
• Replace the nozzle tip.
• Adjust the tension in the rod.
• Increase the micro wire speed.
• Correct the angle and direction of the torch
when welding.
• Adjust the speed configuration of the micro
wire and current.
