Dual digital display intelligent precision pulse spot welder
Thank you for choosing SUNK<O series of products. These products are
designed to make your work more convenient, safe and efficient. Such
that you might become familiar with all the operations of the welder,
an
instruction manual has been included.
INSTRUCTION MANUAL
Attention : Please make sure the GFCI (Ground Fault Circuit Interrupter)
is up to 60A or more before turn on the spot welder.
In order to obtain good weld effect, please don't use the active socket,
and should
be used the wall socket to ensure stable power supply.
Please store this manual
in a safe location for both current and future
reference.

1.Welding pressure adjuster
Please turn up the pressure adjuster in clockwise to
weld thicker thickness . Please turn down the
adjuster in anticlockwise to weld thinner thickness.
Please observe the welding spot wether fastness
and small size. (Notice: When the pressure adjuster
to the maximum or minimum will be not welded .
Please turn the knob to other side and the machine
can work again.)

E. Attention to use ';~
Using notice
1. In order to obtain good weld effect, please don't use the active socket,
and should
be used the wall socket to ensure stable power supply.
2. Please place the spot welder in the ventilated areas to keep the
machine for heat dissipation.
3. Please adjust the suitable welding pressure for welding.
4. Please notice when reaching to setting temperature inside ofthe
spot welder,
it would be protected and stop to work until the temperature
cooling down.
5. Please let the machine take a break when welding over O.2mm
thickness to avoid overheat.
6. Please keep clean of weldi ng pins surface for obtaini ng good
weldi ng spot.
The maintenance of welding pins
1. The weldi ng pi ns on the new machine must be clamped by M4
hexagon screws.
2. Please check oxidation
on 2 pin clamps and grinding it wi th crocus cloth.
3. Please check oxidati
on on welding pin and gri nd i ng it with sand paper.
4. It can be smeared some lubricati on oil on welding pin clamps
and welding pins for avoidi
ng oxidation.
Repair of Simple Fault
Fault
Phenomena Treatment
The machine doesn 't run Please check power and the Insurance behind the machine .
Bad welding effect
Check the power supply If less than 200V and the socket Is
whether connected.
Poor Welding
Check the position of welding needle ,and observe the
welding needle If It Is oxldlzea . Adjust the welding needle.
GFCI-protected
If you use the machine for the first tlmeeeplace another
power supply circuit or change SDA GF I.
Irregular chargering Check the output voltage whether compliance with the battery
pack;the constant current whether set reasonable.
The ch arg in g protected cl osed
Reduction of the charging current,or use In a well ventilated
environment.

& Notice
1. In orderto obtain good weld effect, please don't use the
active socket, and should be used the wall socketto ensure
stable powersupply.
2. Please setthe pressure adjusterto the right parameterto
avoid welding effect
in not good.
3. Please keep the surface welding pins clean and wipe offoxide
with sand paper.
4. Please keep the welding pin
in sharp shape.
5. Please do notworry about the lighting
in flash. SUNKKO 737G
is a high power machine and discharging high current
instantaneously. Because this moment is
in 20ms and it is normal.
