Parts

Installation (SMAW)

Connections
CAUTION   To prevent electric shock please consult information in the “Electrical Requirements” section in pages 3 and 5.

• The fast connections in the electrode holder and the grounding clamp are inserted and turned one quarter of a turn in a clockwise direction in the outlets found in the front panel to be secured.

Inverse Polarity (A)

• Connect the grounding clamp cable to the negative (-) clamping screw in the welder.
• Connect grounding clamp cable (C) to the work piece.
• Connect the electrode holder cable to the positive (+) clamping screw in the welder.

This configuration generates more heat in the electrode, thus producing more penetration with basic electrodes making it ideal to weld thick pieces.
Direct Polarity (B)

• Connect the grounding clamp cable to the outlet (+).

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

• Connect the electrode holder to the outlet (-).
  This configuration generates more heat in the work piece producing less warping of the piece and narrower cords making it ideal to solder thin pieces.

• Connect the feeding cable (D) to the network into the corresponding voltage (127 V~).

WARNING
Before using the welder, it shall be correctly grounded. Failure to comply with this warning propitiates severe personal injuries.

Start Up

Preparation

• Only experience, practice and care can guarantee a good welding job.
• The factor intervening in the welding process are many: required current, distance between the electrode and the work piece, soldering speed and direction, thickness and type of the material, the work piece position, electrode angle and also gauge, type of material and electrode covering. Therefore, is advisable that before welding to carry out practice some in scrap material to determine which are the specific requirements needed for the job to perform.
• The area on the work piece where the soldering will be applied shall be clean, free of rust and paint.
• Joints between sheets with gauges higher than 1/8” shall be beveled to have an adequate weld (A).

Welding

• Set the switch (B) into the ON position.
• Adjust current control knob (C) until proper arc current and intensity are achieved for the job. The current is indicated on the panel display (D).
• Hold the electrode holder or torch as comfortable as possible. Bear in mind that during the welding process, the angle, movement and distance regarding the work piece shall be constant and uniform.
• Aim the electrode tip to the joint to be worked with to generate the arc and start welding.
• Once the arc is lit start soldering keeping always the electrode tip 0.08” away from the work piece. If you make the weld having the electrode supported on the work piece, it could adhere and the weld would have a low quality.

Slag Removal

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

Electrode Replacement

• When the electrode has been consumed 0.4” to 0.8” away from the electrode holder, it is necessary to replace it with a new one to keep on welding.
• CAUTION   • Electrodes are burned in high temperature. Do not try to manipulate the remains of the electrode with your hand. Set the remains in a metal container.
• Open the electrode holder nipper to hold the new electrode by the end that is not covered. Do not hold the electrode by the covered part.

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.
• Altogether with cleaning make a checkup to assure there are no loose parts or components in the welder.
• Keep the welder plug in good repair.
• The plug shall be checked before each use.

Storage

• In the event the welder will be stored a long period of time, keep it in a dry, well ventilated place to prevent humidity getting inside, or to generate rust or toxic gas. Storage temperature vary between -13 °F to 131 °F and relative humidity shall not be over 90%.
