Therefore, each machine has an internal fan to ensure its stable performance. Make sure

the intake is not blocked  or covered, there should be 0.3 meter distance from welding
machine to objects of environment. User should make sure the working area is adequately

ventilated. It is important for the performance and the longevity of the machine.  

b) Do not over load

The operator should keep an eye on  max duty current (Compared  to the selected duty

cycle)  to make sure that the machine working current does  not exceed max duty cycle
current. Over-load current will damage and even burn the machine.
If  machine  exceeds  standard duty cycle,  it   may  stop  working and switch  to  protection
status.   The   temperature   control   switch   is   activated   by   over   heat   released   under   this

circumstance. Meanwhile, the over heat indicator lights up. Under this situation, you do not
need to pull out the power plug since the internal fan can work to cool down the machine.

When the over heat indicator stops, the  temperature  has been lowed down to standard
range, operator is able to starting working again.   

  

c)

No over voltage

Power voltage can be found in diagram of parameters. Automatic compensation circuit of
voltage will assure that welding current keeps is in allowable range. If power voltage is

exceeding allowable range limits, it can damage the components of machine. The operator
should understand this situation and take preventive measures.

d) There is a grounding cable behind welding machine with a mark. Before operation, welding

crust   must   be   grounded   reliably   with   cable,   in   order   to   prevent   static   electricity,   and

accidents for electricity leaking.

4.4 Welding problems and resolution

The phenomenon listed below may happen due to relevant accessories used, welding material,
surroundings and power supply. Pleas improve surroundings and avoid these problems.

Arc starting difficulty. Arc interruption happens easily.

a)

Examine whether grounding wire clamp contacts with the work pieces well. 

b)

Examine whether each joint has improper contact.

The output current fails to reach rated value.

The deviation of power voltage from rated value may cause that the output current does no

accord   with   adjusted   value.   When   the   power   voltage   is   lower   than   rated   value,   the
maximum output current may be lower than rated value.

The current can not keep stable during operation.

This situation may relate to the following factors: 

a) The voltage of electric power network changes; 

b) Serious interference from electric power network or other electric facilities.

Gas vent in welds.

a) Examine whether the gas supply circuit has leakage.
b) Examine whether there is sundries such as oil, dirt, rust, paint etc. on the surface.
