ORIGINAL INSTRUCTIONS
Welcome to Autojack!
Dear Customer, Congratulations on your purchase.
Before using this product for the first time, please be sure to read these
instructions for use.
They provide you with all the information necessary for using the product
safely and to ensure its long service life.
Closely observe all safety information in these instructions!
GENERAL POWER TOOL SAFETY WARNINGS
WARNING, please read all safety warnings and instructions.
Failure to follow the warnings and instructions may result in electric shock,
fire, and/or serious injury.
Save all warnings and instructions for future reference.
The term “Power tool” in the warnings refers to your electric (corded) power
tool or battery-operated (cordless) power tool.
-
Work area safety
a) Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks that may ignite dust or fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control. -
Electrical safety
a) Power tool plugs must match the outlet.
Never modify the plug in any way.
Do not use any adaptor plugs with grounded power tools. Unmodified plugs and matching outlets will reduce the risk of electric shock.
b} Avoid body contact with grounded surfaces, such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. The use of an RCD reduces the risk of electric shock. -
Personal safety
a) Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
b) Use personal protective equipment. Always wear eye protection. Protective equipment such as dust masks, non-skid safety shoes, hard hats, or hearing protection used for appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off position before connecting to a power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards. -
Power tool use and care
a) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier
g) Use the power tool, accessories and tool bits, etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation. -
Service
a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
b) If the replacement of the supply cord is necessary, this has to be done by the manufacturer or its agent in order to avoid a safety hazard. -
Additional Safety
Instructions for welders
Welders have many sources of danger. It is therefore particularly important for the welder to comply with the following rules so as not to place themselves or others in danger and to avoid endangering people and equipment.
a) Have all work on the mains voltage system, for example on cables, plugs, sockets, etc., performed only by trained electricians. This particularly applies to configuring intermediate cables.
b) If an accident occurs, disconnect the welding power source from the mains immediately.
c) If electric touch voltages occur, switch off the welding set immediately and have it checked by an expert.
d) Always check for good electrical contacts on the welding current side.
e) Wear insulating gloves on both hands for welding. These offer protection from electric shocks (idling voltage in the welding circuit), harmful radiation (Heat and UV radiation) and glowing metal and slag spatter.
f) Wear firm, insulated footwear. Your shoes should also protect you in wet conditions. Open-toed footwear is not suitable since falling droplets of glowing metal will cause burns.
g) Wear suitable clothing, do not wear synthetic clothes.
e) Do not look into the arc with unprotected eyes, use only a welding safety shield with the proper safety glass in compliance with DIN standards. In addition to light and heat, which may cause dazzling and burns, the arc also gives off UV radiation. Without proper protection, this invisible ultraviolet radiation causes very painful conjunctivitis, which will only be noticeable several hours later. In addition, UV radiation will cause sunburn-type symptoms on unprotected parts of the body.
f) Personnel or assistants in the vicinity of the arc must also be notified of the dangers and provided with the required protection; if necessary install safety walls.
g) Ensure adequate ventilation for welding, particularly in small rooms since the process causes smoke and harmful gases.
h) Do not carry out any welding work on tanks that have been used to store gases, fuels, mineral oil or the like, even if they have been empty for a lengthy period of time, since any residue will result in a danger of explosion.
l) Special regulations apply in areas where there is a potential risk of fire and/or explosion.
m) Welds that are exposed to large stresses and must comply with safety requirements may only be completed by specially trained and approved welders. Examples of such welds include pressure vessels, rails, trailer hitches, etc.
n) It must be noted that the protective conductor in electrical systems of appliances may be destroyed by the welding current in the event of negligence, for example, if the earth terminal is placed on the welding set casing to which the protective conductor of the electrical system is connected. The welding work is completed on a machine with a protective conductor connection. It is, therefore, possible to weld on the machine without having connected the earth terminal to it.
In this case, the welding current will flow from the earth terminal through the protective conductor to the machine. The high welding current may cause the protective conductor to melt.
o) The fuses on the supply cables to the main sockets must comply with the relevant regulations (VDE 0100). To comply with these regulations, only fuses or circuit breakers suitable for the crosssection of the cables may be used (for earthing contact sockets max. 16 A fuses or 16 A circuit breakers). The use of too high a fuse may result in cable burning and fire damage to the building. -
Additional Safety Instructions for Constricted and Wet Areas When working in constricted, wet, or hot areas, use insulating supports and intermediate layers as well as slip-on gloves made of leather or other nonconductive materials to insulate your body against the floor, walls, conductive parts of the machine and the like. If you use small welding transformers for welding in places with an increased electrical risk, for example in constricted areas with conductive walls, (tanks, pipes, etc.), in wet areas (which make work clothes wet), and in hot areas (perspiration on work clothes), the output voltage of the welding set when idling must not exceed 48 V (effective value). Therefore, the appliance may not be used for these purposes because its output voltage is higher than this.
-
Additional Safety Instructions for safety clothing
a) While working, the welder must protect his entire body from radiation and burns by wearing suitable clothing and a faceguard.
b) Slip-on gloves made of a suitable material (leather) must be worn on both hands. They must be in perfect condition.
c) Suitable aprons must be worn to protect clothing from sparks and burns. A safety suit and if necessary, head protection must be worn if required by the type of work in question, e.g. overhead welding.
d) The safety clothing used as well as all accessories must comply with the “Personal Safety Equipment” directive. -
Additional Safety Instructions for Protection from Radiation and Burns.
a) Provide information about the risk to eyes at the working site in the form of a poster with the wording “Caution – do not look at the flames”.
Workplaces are to be screened off wherever possible so that personnel in the vicinity are protected. Unauthorized persons are to be kept away from the welding work.
b) The walls in the immediate vicinity of stationary workplaces should not have light color or a sheen. Windows up to head height are to be protected against radiation passing through them or reflecting off them, for example by coating them with a suitable paint. Do not store or use the equipment in wet conditions or in the rain. Use the equipment only indoors. -
Using an Extension Cable.
a) If an extension cable is required, use an approved triple-core extension cable suitable for the power input of the tool.
b) Grounded tools always require a three-wire extension cable.
c) As the distance from the supply outlet increases you must use a heavier gauge extension cable. Using extension cables with inadequately sized wire causes a serious drop
in voltage, resulting in loss of power and possible tool damage.
d) The smaller the gauge number of the wire the greater the capacity of the cord.
e) When using a cable reel, always unwind the cable completely.

OPERATION
When ARC welding, your amperage/current should be determined by the electrode
size, the knob (function switch on the image below) adjusts this setting.
Before welding, ensure that you have your welding mask on and set to the arc
function if applicable.
The electrode should be around 1.5mm to 3mm away from the workpiece until the
arc is made, once the arc has started, move the rod in a steady motion in one
direction across where you would like your weld. Once you have finished your
weld, pull the rod away from the workpiece and remove any excess weld spatter
with the wire brush that is supplied with your welder and a hammer. Before
starting a new weld, inspect the rod used to make sure that the tip is
concentric. If not, you can re-sharpen the tip using a grinding wheel or
change the rod completely.
When the welder has been used for a prolonged period of time, “OVERHEAT” may
show on the display.
If this happens, please stop using the machine until it disappears.
Turning the machine off when in this state can cause damage to an internal
PCB.
MAINTENANCE AND SERVICE
The following points will aid with keeping your D-ARC welder in good condition to ensure peak performance:
- Regularly clear metallic dust from inside of the machine (use a low-pressure air gun)
- Keep the welder in a dry place when not in use
- Check that the earth clamp can clamp sufficiently, replace if necessary
- Make sure all cables are in good condition with no nicks or degradation to the sheathing
- Check all connections are usable with no oxidization or wear to any contacts
