ERROR LIST
MESSAGES
E1
CAUSE
The value of one of the stored parameters exceeds the pre-set limits. This could be caused by a loss of data due
to any interference or malfunctioning.
REMEDY
Check all the values set in the parameters and correct them if necessary. Contact to the aftersale service if the
trouble occurs frequently.
E 2
CAUSE
During the pulse operation the WELDING TIME is set to a value higher than 25. This parameter cannot be higher
than 25 in the pulse mode operation.
REMEDY
Set the welding time to a value lower or equal to 25 cycles.
E 3
CAUSE
During the pulse operation the total welding time (WELDING TIME x IMPULSE NUMBER) is higher than the limit
of 150 cycles. Do not exceed this value so as not to overheat the machine.
REMEDY
Decrease the welding time or the impulse number so that their product is lower or equal to 150 cycles. The
welding times in car body shop repair are very short ones (see table no. 2 Page 1
2
). With longer times it is
necessary to limit the number of spots in order to avoid over heating.
E 4
CAUSE
The compensation function is enabled and the control unit has extended the welding time up to the maximum limit
of 99 periods. The set welding time has not been carried out with a welding current higher than the limit.
REMEDY
Press a key to cancel the error. Before restarting the welding processor check the welding conditions. If the
pieces are too oxidised they must be cleaned.
MULTIFUNCTION GUN ITEM 338075
Connect both gun item 338075 and ground cable item 333469 to clamps (5). The ground cable must be connected to the
car body metal nearby the weld area. (Variations of such a distance can require a different welding control unit
adjustment;
the farther the ground is from the area to weld the higher the welding current and time should be
.
This gun enables to carry out the following functions:
z
Single side welding
. Max. thickness of sheets on electrode side is to be 0,8 mm; higher thickness of the counter side
sheet. Always work on perfectly clean and touching sheets.
The best results with the multifunction gun can be reached by maintaining electrode (F) in good conditions and with a
max. diameter of 3,5 mm.
Handle the gun keeping the electrode perfectly perpendicular to the surface to be welded, press strongly by means of
electrode (F) and operate trigger (G). Welding examples A, page 15.
z
Straightening of car body panels heavy deformations
.
There are two possible procedures:
1. Welding nails (or washers) and consequent pulling by means of the slide hammer (Fig. B, page 15).
2. Use of the 3 point’s star. Welding example C, page 15.
z
Localised heating
for small denaturing deformations of for eliminating oil conning dent pulling are carried out by
means of the carbon electrode. Example D, page 15.
