MIG/MAG Invertorová svářečka / MIG/MAG inverter welding unit MISA303
12.2 Voltage indicating
The voltage meter on the front panel can indicate the actual welding voltage or preset volt-
age.The indicating number has the precision of 0.1V .The meter indicates the preset during no
welding.
12.3 Current indicating
The current indicating meter on the front panel indicates the actual welding current during the weld-
ing.The adjusting range is
MISA303: -80±10~-330±20.The max preset scale can be -200~-300 in special requirements.
12.4 Power indicating
If the indicating light is on the control circuit connects the power already.
4.1.4Switch for gas inspection
Before welding, if switch is "ON",you can adjust the gas flow.
During welding,switch is "OFF",otherwise the flow directly .
Warning
In order to remind the operator.we design the warnings as following .
12.4.1 Excess temp
In the condition of more than 40
℃
temperature,large current is used continuously on MISA303
(I2>160A),efficiency radiator temperature id more than 80±5
℃
,overheat circuit begins working.The indi-
cating light is on ,the power stop the welding automatically.The fan running continuously.If the temperature
is lower,the indicating is off,the power can work and weld can be continued automatically ,Remind:Don't
turn off the machine while the indicating overheat light is ON.
Warning
If the circuit is over current ,the light is ON.The control circuit stop the power automatically.
12.5 Safe and installation caution
Read the safe caution before installation and operation .It come down to the high voltage electrici-
ty,electric Arc and high temperature splash.So keep the safe regulation ,operate the machine proper-
ly,avoid the danger of electricity and high temperature arc.
•
Check if any damage ot out looking ot the welder.
•
Confirm the capacity (MISA303):more than 50A.
•
Power source is grounded,diagram 6
•
Prohibit the combustible goods in the welding locale.
•
There is fire proof measure in the welding locale with favorable ventilated condition.
•
There is smoke discharge system if the welding is operated inside the house in order to keep
the safety of workers.
•
The welding operator must be professional workers.
