3.4. LOCAL CONTROLS
/I - potentiometer R11
MIG/MAG: Local control for wire feed speed 0…18 m/min or 0…
25 m/min (Promig 300)
MMA welding: Welding current control, 10 A … max current of power source
U - potentiometer R12
MIG/MAG: Local control for voltage of PRO power source, 10 V …
max. MIG voltage of power source
MMA welding: No operation
3.5. REGULATION FOR SHIELDING GAS FLOW
Shielding gas flow can be regulated with flow regulator 5…25 l/min. Display is calibrated for
Ar CO
2
mixed gas (75% Ar, 25% CO
2
). By other gases the meter error remains within ±10%
limits compared with real flow.
The gas flow regulator shows within ± 10% limits right only when angle of
deflection is smaller than 15° in regard to vertical.
Regulate the meter always when the unit is in vertical position.
Gas flow is read in the centre of swimmer.
3.6. SIGNAL LAMP H12 INDICATING MISSING OF
SHIELDING GAS
The unit is equipped with shielding gas guard which by missing of shielding gas
prevents welding start and stops welding, if arrival of shielding gas is prevented
during welding.
Red signal lamp is illuminated:
Welding is prevented until shielding gas pressure is adequate.
Red signal lamp is not illuminated:
Welding is allowed.
3.7. SIGNAL LAMP H11 FOR ERRORS
By Promig 200 and 300 units check by each start, if there are error states in the
equipment, if error states are observed, the error state is shown by blinking of
signal lamp H11 for errors. E.g. one short flash means error code Err 1 and two
short flashes indicate error code Err 2 etc.
Error codes are:
1 short flash, Err 1:
Promig has gone over to MMA welding, though you have already
selected MMA welding on power source panel.
2 short flashes, Err 2:
You are pressing on start switch of gun, when data transmission
between Promig and PRO is broken (defect in control cable or in
connector), or you are pressing on gun switch, when MMA welding
has been selected on control panel of power source.
4 short flashes, Err 4:
You are pressing on start switch of gun and selecting switch S12 for
cooling mode is in liquid position and you have forgotten to switch-on
the PROCOOL cooling unit or you have forgotten to connect it to
equipment.
