AWELCO EXTRA 170 DC generator for MM welding

The kit includes the following accessories: earth clamp, electrode holder

INTRODUCTION

This device is a generator inverter current (DC) suitable to the MMA welding. Thanks to the inverter technology which allows achieving high performances while keeping small SIze and weight, the welder is portable and easy to handle. The device is suitable for welding with coatedelectrodes rutile and can be connected to power generators with power equal to or higher than that reported in Table 2. It is equipped with “HOT START”, “ARC FORCE” and “ANTI STICK” (Maximum Output control current) functions

DESCRIPTION OF THE MACHINE

• A Welding current Knob.
• B Thermal protection LED indicator.
• C Negative pole (-)
• D Positive pole (*).
• E ON-OFF switch.
• F Power Cord.
• G Power Led
• H Display

INSTALLATION

The installation must be made by trained personnel in compliance to the standard IEC 60974-9 and the current and local legislation. To lift the machine it must be used
the handle positioned on top of the product with the machine in OFF position. The input voltage must match the voltage indicated on the technical plate located on the product.
Use the machine on electric system having supply features and power protection (fuse and / or differential Switch) that are compatible with the current required for its use. For more details see the information on the plate placea o he machine.

HOW USE IT

Warning: Use all precautions required in the safety general manual beTore operaung the Welder, reading careruily the risks linkea to the welding process. connect tne plugs or the earth clamp and the electrode holder to the connectors of the machine (Fig 1, C and D) rotating the attack in order to ensure a good grip.
Choose the polarity FIg.2 (1. forward or 2. reverse) depending on the coating of the electrodes (for more information see the information on the electrodes packaging).
Connect the earth clamp to the work piece to be welded trying to establish a good point of contact between the metal and the clamp, as close as possible to the area to be welded, insert the electrode into the electrode holder.
Insert the plug into the power outlet and turn on the welding machine by pressing the switch (Fig 1, E) to the ON position.
Select the welding current (FIG 1, A) as a function of the type of electrode selected (Tab. 1). Start the welding operation using all the necessary protections for the securit
When welding is completed, turn off the machine and release the electrode trom the electrode holder

THERMAL PROTECTION

The machine is used for hard work cycle, the thermal protection device will protect the machine from over heating. Ihe yellow LED ON indicates that the thermal protection Is on. It is possible to start welding again once the LED IS off.

MAINTENANCE
The all maintenance services must be done from qualified personnel in compliance to the norm (EC 60974-4).

Trouble Shooting

The device is not delivering current and the yellow indicator LED of

thermal protection lights up.

| The welder thermal protection has turned on.| Wait for the end of the cooling time, around 2 minutes. The

indicator led turns off.

The device is on but it is not delivering current.

| The cable of the earth clamp or electrode holder is not connected to the welder.| ****

Turn off the machine and check the connections.

Your unit does not weld correctly.| Polarity error| . Check the polarity advised on the electrodes packaging.

People who have been trained and knoW about the “Rules for the installation of electrical installations” and “Safety rules for the operation of electrical installations” are allowed to work with a welding machine The welding machine can be used outdoors.
When you work outdoors, it is necessary to provide protection against direct sunlight and precipitation.
NOTE: During the winter, If the inverter is brought to a heated room from the street or from a cold room, it should not be turned  on for the next 6 hours to warm up to the ambient temperature.

Storage conditions:

The welding machine should be stored in a dry room at a temperature not lower than – 40 C and not higher than+55 C with a relative humidity of not more than 80%. The storage and transport conditions should exclude the possibility of mechanical damages, the effects of atmospheric precipitation and chemical fluids. The welding machine should be stored out of the reach of children. The service life of the welding machine is at least 5 years, the storage life is 5 years. The specified service life is valid when the user meets the specified requirements. Date of manufacture is indicated on the body of the device
