TROUBLE SHOOTING
For your safety and to avoid Electrical Shock, please observe all safety notes and precautions
detailed in this manual.
Note:
• Our equipment as described in this manual conforms to all applicable rules and regulations of the
‘LowVoltage Directive’ (European Council Directive 73/23/EEC) as set out and amended by Council
Directive 93/68/EEC) and to the National legislation for the enforcement of this Directive.
• Our equipment as described in this manual conforms to all applicable rules and regulations of the
European Council Directive 89/336/EEC, (EMC Directive) and to the National legislation for he
enforcement of this Directive.
CAUTION
1. Working Environment.
1.1 The environment in which this welding equipment is installed must be free of grinding dust, corrosive
ials etc, and at no more than maximum of 80% humidity.
1.2 When using the machine outdoors protect the machine from direct sun light, rain water and snow etc;
the temperature of working environment should be maintained within -14°F to +104°F..
1.3 Keep this equipment 1ft distant from the wall.
1.4 Ensure the working environment is well ventilated.
2. Safety Tips.
2.1 Ventilation
This equipment is small-sized, compact in structure, and of excellent performance in amperage output.
The fan is used to dissipate heat generated by this equipment during the welding operation.
Important: Maintain good ventilation of the louvers of this equipment. The minimum distance between
this equipment and any other objects in or near the working area should be 1ft. Good ventilation is
of critical importance for the normal performance and service life of this equipment.
2.2
Thermal Overload protection.
Should the machine be used to an excessive level, or in high temperature environment, poorly
ventilated area or if the fan malfunctions the Thermal Overload Switch will be activated and the
machine will cease to operate. Under this circumstance, leave the machine switched on to keep the
built-in fan working to bring down the temperature inside the equipment. The machine will be ready for
use again when the internal temperature reaches safe level.
2.3
Over-Voltage Supply
Regarding the power supply voltage range of the machine, please refer to “Main parameter” table.
This equipment is of automatic voltage compensation, which enables the maintaining of the voltage
range within the given range. In case that the voltage of input power supply amperage exceeds the
stipulated value, it is possible to cause damage to the components of this equipment. Please ensure
your primary power supply is correct.
2.4 Do not come into contact with the output terminals while the machine is in operation. An electric shock
may possibly occur.
MAINTENANCE
Exposure to extremely dusty, damp, or corrosive air is damaging to the welding machine. In order to
prevent any possible failure or fault of this welding equipment, clean the dust at regular intervals with clean and
dry compressed air of required pressure.
Please note that: lack of maintenance can result in the cancellation of the guarantee; the guarantee of this welding
made sealing of the machine without the consent of an authorized representative of the manufacturer.

BUILT TO GET THE JOB DONE
Standard rule of thumb is the thicker the material the more amperage required.
On thick material, set the machine to full output and vary your travel speed. On thinner material, you need to turn down the amperage and
change to a lower-amperage tip to maintain a narrow kerf. The kerf is the width of the cut material that is removed during cutting.
Amperage and speed are critical to producing a good quality cut. The faster you move (especially on aluminium), the cleaner your cut will
be. To determine if you're going too fast or too slow, visually follow the arc that is coming from the bottom of the cut. The arc should exit
the material at a slight angle away from the direction of travel. If it's going straight down, that means you're going too slow, and you'll have
an unnecessary buildup of dross or slag. If you go too fast, it will start spraying back onto the surface of the material without cutting all the
way through. Because the arc trails at an angle, at the end of a cut, slow your cutting speed and angle the torch in to cut through the last bit
of metal.
-
easiest way to reduce bevel is by cutting at the proper speed and height for the material and amperage that is being cut.
Correct torch height and square
to the material.
Minimum bevel & equal bevel
Longest consumable life
Torch angled to the material.
Unequal bevel, one side may be
excessively beveled.
Torch height too high.
Excessive bevel, plasma stream
may not cut all the way through
the material
Torch height too low.
Reverse bevel. Tip may
contact the work and short out
or damage the tip.
-
which maintains a narrow plasma stream at lower settings for use on thin-gauge material. Using a 25 amp tip at an 60 amp setting will blow
Electrons arc across the gap, ionizing and super
heating the air creating the plasma stream. The electrode contains an insert in the end made of a highly conductive material called hafnium.
This insert erodes with use and develops a pit in the end of the electrode, when the pit becomes too much poor quality cuts will result and
necessitate replacement of the electrode.
