AUTO IDLE
Operation
When the engine is switched on it immediately reaches a ma-
ximum speed of 3720 rpm for approximately 6/7 seconds for
easy start up, after which it automatically decreases and idles at
2650 rpm. It remains at this speed until current is drawn when
set to weld or auxiliary power.
When set to weld mode the machine reaches maximum engine
speed as soon as there is minimum contact between the tip of
the electrode and the piece to be welded and also when set to
generation drawing a minimum of 250 – 300 W
The machine returns to minimum 6/7 seconds later if power is
not drawn during welding or generation.
Checking and adjusting idling speed
- Check idling speed when COLD;
- When the engine is switched on it reaches maximum speed;
after 6/7 seconds it decreases automatically to idle. Check
the speed when the engine idles;
- The idling speed corresponds to 47-50 Vdc at the welding
sockets or the equivalent at 2650 rpm.
Minimum welding voltage TOO LOW
- From Fig. 1 proceed as follows:
• when the machine idles (engine cold)
•
Keep pin A locked (8 mm spanner) and unscrew nut B (7
mm spanner)
• Again with pin A locked, turn nut C clockwise (7 mm spanner)
1 - 3 mm: The more it is extended the more the idle speed
increases
•
Tighten nut B on pin A and check the idling speed.
Minimum welding voltage TOO HIGH
- From Fig. 1 proceed as follows:
• When the machine idles (engine cold)
•
Keep pin A locked (8 mm spanner) and unscrew nut B 1-3
mm (7 mm spanner)
• Again with pin A locked, turn nut C anticlockwise (7 mm
spanner) until nut B touches pin A
• Tighten nut B against pin A and check that the idling speed
is correct.
Adjusting the maximum engine speed
Calibration of maximum RPM (Revolutions Per Minute)
To check that the maximum engine RPM is correct, simply
measure that the welding tension with no-load (not under load)
at the maximum RPM must be between 69-71V.
Adjustment is made by the screw (A) Fig. 2.; first, however,
the accelerator lever lock nut must be loosened, then carry out
the adjustment, turning the screw (A) clockwise to reduce the
maximum and anti-clockwise to increase it. Once the calibration
has been carried out, re-tighten the accelerator lever lock nut.
