Problems Solving - MAKin 220 MMA Bedienungsanleitung

Err -t- (temp – overheating)
activation of the machine heat protection. Wait till the machine cools down and
then continue your work.
Err 1 (poWersupplY – over/undervoltage in the power supply).
the input clamps' voltage (power supply cable) is outside the machine toleration.
Err 8 (err out short)
When turning the machine on - short on the input clamps (for instance the
grounding cable and cable with the electrode holder are shorted, or it can signify
a machine problem).
- - - - - - (antistick)
antistick function activation. this function is activated during welding by sticking
of an electrode or during arc ignition in the tiG method.
some error messages can be deleted only by turning the machine on and off with
the main switch.

Problems solving

display is not on - no voltage is entering the machine.
• check the main supply cable and replace faulty parts.
the machine is not welding properly.
during welding the spatter is big, the weld is porous.
• check the welding parameters setting or reset them.
• check the gas connection and attachment of the gas hose.
• check the grounding clamp, make sure it is properly attached and the grounding
cable is not damaged. change the grounding position and replace damaged
parts if necessary.
• check the welding torch cable and connector. tie connections and replace
damaged parts.
• check replacement parts of the welding torch. clean and replace damaged
parts.
the welding machine is overheating and control light is on
• make sure that there is enough empty space behind and in front of the
machine, which would ensure proper air circulation needed for cooling of the
machine.
• make sure the cooling grills are clean.
the mma method – the current is not constant
• if the arc-force function is on, this is ok. this function dynamically adjusts the
value of the welding current in order to stabilize the arc and ensure maximum
welding quality.
thin material is burned through during arc ignition
• check the setting of the hotstart function. set it to a lower value or turn the
function off.
Maintenance
please pay attention to the main power supply! it is necessary to disconnect it
during any manipulation with the welding machine.
during maintenance planning the frequency and circumstances of the machine's
use must be consid-ered. considerate use and preventive maintenance helps in
avoidance of unnecessary breakdowns and failures.
reGular maintenance and check-up
perform the check-up according to csn en 60974-4. always check the condition
of the welding and supply cables before using the machine. do not use dam-
aged cables.
perform visual check-up:
1) torch/electrode holder, the welding current clamp
2) power supply
3) welding circuit
4) covers
5) control and indicator elements
6) overall condition
everY siX months
disconnect the machine from the electrical outlet and wait for about two minutes
(the charge inside the machine condensers will dissipate). then remove the
machine cover. clean all dirty electrical connections and retie any loose ones.
clean all internal parts from dust and dirt, for instance with a soft brush or with
a vacuum cleaner.
note: be careful when using compressed air in order to not damage any parts.
never use any solvents or diluents (such as acetone, etc.); plastic material and
front panel lettering could be damaged in such procedures.
only a technician with electro technical qualification may repair this machine.
storaGe
the machine must be stored in a clean and dry room. protect the machine from
rain and direct sunlight.
