Parts

Installation (SMAW)

Connections
CAUTION To prevent an electric shock, the user must see the information in “Power Requirements” in page 3 and 5.

• The fast connections of the electrode holder and the ground clamp are inserted and turned one quarter of a turn in a clockwise direction in the outlets set in the front panel to secure perfectly.
• Press the process selector to set the welder working in SMAW mode (coated electrode).
  NOTE The upper LED in the selector will light on.

Reverse Polarity (A)

• Connect the grounding clamp cable to the negative (-) output clamping screw of the welder.
• Connect the grounding clamp (C) to the work piece.
• Connect the electrode holder cable to the positive (+) output clamping screw of the welder. This configuration generates more heat in the electrode, which produce more penetration with basic electrodes, making it ideal to weld thick pieces.

Direct Polarity (B)

• Connect the grounding clamp cable to the positive (+) output.

• Connect the grounding clamp (C) to the work piece.

• Connect the electrode holder cable to the negative (-) output.
  This configuration generates more heat in the work piece, thus producing less malformation in the work piece and narrower joints making it ideal for thin pieces.

• Connect the power cable (D) to the power network to the work voltage (127 V ).

TIG Connection

• This inverter welder can also be used for TIG welding, a high-quality welding process with non-consumable tungsten electrodes and arch protected with inert gas like argon gas o helium.

• TIG welding is ideal to weld stainless steel, iron and copper.

• With this process, a AN-SI-12/16/20 torch and a can of protective gas are required (not included).

• Press the lower arrow in the process selector to set the welder into the TIG mode. (Tungsten electrode).
  NOTE The LED facing down will turn ON.
  

• To start the arch, set the nozzle making an angle onto the work piece (1).

• Lift the torch, not separating it from the work piece to approach the electrode to the work piece (2).

• When starting the electric arc, lift the torch so that the electrode tip is 0.08” away from the work piece (3) and start welding.

• It is advisable to keep the electrode 90° vertical during the welding to guarantee the protection of the gas.

Start Up

Preparation

• Only through experience, practice and care a good welding process can be guaranteed.
• The factors arousing in the welding process are many: current required, distance between the electrode and the work piece, speed and direction of the welding, thickness and type of material, position of the work piece and welding  direction, and also, the gauge, material and covering of the electrode. Thus, it is advisable that before carrying out a weld, try to practice in scrap material to determine which are the specific requirements for the job ahead.
• The area in the work pieces where the weld is to be applied shall be clean, free of oxidation and paint.
• The joints between sheets with calibers larger than 1/8” shall be beveled so the weld will be adequate (A).

Welding

• Set the switch (B) in the ON position I.
• Adjust the current control adjustment (C) until reaching the adequate arch current and intensity suitable for the job. Current is indicated in the panel screen (D).
• Hold the electrode holder or torch in the most comfortable position possible. Be aware that during the welding process, the angle, movement and distance with regards to the work piece shall be constant and uniform.
• Aim the electrode tip towards the joint to be welded to generate the electric arch and be able to start welding.
• Once the arch is ON start welding, keeping always the electrode tip 0,08” away from the work piece. If welding with the electrode onto the work piece, it could stick and the weld would have a poor quality.
• In the event of overheating, the welder will stop working and the two thermal protection indicating lights (E) will be ON. Do not turn OFF the welder. Wait for the indicator lights turns OFF to use it again.

VRD security system

• Activate the VRD (Voltage Reduction Device) system by pressing the button (F) to reduce voltage during the bait phase to prevent possible discharge to the operator.
• It is recommended to activate it in risky situations, such as when welding in confined spaces, wet environments, working in heights and in mining industry.
• When the VRD system is activated it is necessary to force contact between the electrode and the workpiece for up to two seconds to generate the arc and start welding.

Slag Removal

• Upon finishing the welding job, use a wire brush to remove slag from the welding joint surface.
• CAUTION Wait until the slag has cooled down and hardened to be able to remove it.
• When hitting or brushing slag to remove it, there can be particles shooting out. Wear eye protection and keep bystanders away.

Electrode Replacement
SMAW:

• When the electrode has burned 0.4” to 0.7” from the electrode holder, replace wit with a new one to be able to keep on welding.
• The electrode burns in high temperatures. Do not try to handle the electrode remains with your hand. Put the remains in a metal container.
• Open the electrode holder tong to hold the uncovered end of the new electrode. Do not hold the electrode in the covered part.

TIG:

• Tungsten electrodes shall be sharpened to guarantee the weld quality in a longitudinal direction.
• The tungsten electrode tip gets deformed due to the heat. Therefore, when the tip is not showing an angle, it is recommended to sharpen it again.

Examples of welding

Maintenance

• The correct use and regular cleansing extend the useful life of the welder.
• CAUTION Only qualified personnel shall carry out repairs. We recommend visiting a Authorized Service Center to repair your welder, get supplies or accessories.

Regular Maintenance

• Clean dust from the welder with compressed air. If there is too much dust present, clean immediately. Under normal conditions clean once a year. If the welder is exposed to a lot of dust, cleaning should be carried out every three  months.
