Polysoude P6 - Gas, Cooling, Ignition, Arc, Short Circuit Issues

THE ART OF WELDING
P6
66-92 PN-0509076 Rev. 16
Problem (Consequence) Possible causes What to do
Gas
(Stop immediately)
Gas bottle empty or valve closed Check, replace or open
Quick coupling of the welding head
badly connected
Check
Solenoid valve defect
Must be checked and, if necessary,
replaced by a qualifi ed electrician
Cooling circuit
(Imposed downslope)
Coolant level too low Check and correct
Cooling circuit blocked
Check, empty and clean the circuit,
clean the water fi lter. Fill up with
fresh coolant
Shunt of the cooling circuit not con-
nected (air cooled closed chamber
welding heads) - see power source
version
Check and correct (§ 4.3.3)
Quick couplings of the welding head
badly connected
Check and correct
Fuse defect Check and change (§ 6.2.1)
Pump defect
Must be checked and, if necessary,
replaced by a qualifi ed electrician
Polygaine defect (MU welding heads) Replace
Ignition
(Stop immediately)
Weld current cable badly connected or
cut
Correct or replace
Earth connection not clamped at a
clean zone
Move earth connection (§ 4.3.2 or
4.3.6)
Electrode contaminated or too far from
workpiece
Consult operation manual of the
welding head for electrode changing
Polygaine defect (MU welding heads) Replace
Ignition device not fi tted or badly posi-
tioned (welding heads MU, TP, TS …)
Change position
Gas not suitable, gas fl ow rate not
adapted
Try with argon
Power source badly adjusted Contact Polysoude After Sales Service
Current source defect Contact Polysoude After Sales Service
Arc loss
(Stop immediately)
Electrode tip damaged or wrongly
prepared
Consult operation manual of the
welding head for electrode changing
Wrong distance electrode/workpiece Correct
Poor gas protection
Check fl ow rate, gas diffuser, clean,
correct
Weld current programmed too low Correct
Ignition help mounted too near to the
torch (heads MU, TP, TS …)
Correct the position
Short circuit
(Stop immediately)
Electrode touches workpiece Correct
Electrode touches fi ller wire Modify position of wire entry
Ignition device in contact with the
torch (heads MU, TP, TS …)
Correct the position
Bad insulation between wire guide and
torch
Check and correct
