Page 3: General Safety Rules
WARNING: Read and understand all instructions. Failure to follow all instructions listed below may result in serious injury. Do not allow persons to operate or assemble this ACDC200LCD CAUTION until they have read this manual and have developed a thorough understanding of how the ACDC200LCD operates. - Page 4 • Keep hands and fingers away from moving parts and stay away from the drive rolls. • Do not point welding torch at any body part of yourself or anyone else. • Always use this welder in the rated duty cycle to prevent excessive heat and failure. ACDC200LCD...
- Page 5 Specific Areas of Danger, Caution or Warning Electrical Shock • Electric arc machines can produce a shock that can cause injury or death. Touching electrically live parts can cause fatal shocks and severe burns. While welding, all metal components connected to the wire are electrically hot.
- Page 6 • Do not have on your person any items that are combustible, such as lighters or matches. • Keep work lead connected as close to the weld area as possible to prevent any unknown, unintended paths of electrical current from causing electrical shock and fire hazards. ACDC200LCD...
- Page 7 Hot Materials • Welded materials are hot and can cause severe burns if handled improperly. • Do not touch welded materials with bare hands. • Do not touch welding torch nozzle after welding until it has had time to cool down. Sparks/Flying Debris •...

Broken parts will affect the ACDC200LCD operation. Replace or repair damaged or worn parts immediately. • When ACDC200LCD is not in use, store it in a secure place out of the reach of children. Inspect it for good working condition prior to storage and before re-use. -
Page 9: Description
DESCRIPTION The ACDC200LCD series is digitally controlled machine which can be used for STICK, AC TIG, DC TIG & PULSE TIG welding. This unit uses 1~Phase 240V, 50/60HZ AC power. Specifications and Dimensions Item ACDC200LCD Input voltage 240V (220 ~ 240) - Page 10 2T/4T select/ Save/Load: Switches between 2T & 4T. Press and hold will give the ability to load pre-set parameters. Parameters This part is to show the procedure, when the indicator lights, the corresponding parameter can be adjusted with the select knob. See following details: ACDC200LCD...

Page 12: Installation
It is strongly recommended that an extension cord should not be used because of the voltage drop they produce. This drop in voltage can affect the performance of the welder. If you need to use an extension cord must use conductors of at least 6mm and less than 8m length. ACDC200LCD... - Page 13 Setting Up The Work Piece Welding positions There are two basic positions, for welding: Flat and Horizontal. Flat welding is generally easier, faster, and allows for better penetration. If possible, the work piece should be positioned so that the bead will run on a flat surface. Preparing the joint Before welding, the surface of work piece needs to be free of dirt, rust, scale, oil or paint.
- Page 14 (left). The gas valve is located on the back panel of the welder and activated by the trigger. Gas flow should be heard when the trigger is activated. Avoid unnecessary gas loss by closing the tank valve when finished welding. ACDC200LCD...

Page 15: Stick (Mma) Operation
STICK (MMA) OPERATION Electrode The welding electrode is a rod coated with a layer of flux. When welding, electrical current flows between the electrode (rod) and the grounded metal work piece. The intense heat of the arc between the rod and the grounded metal melts the electrode and the flux. - Page 16 Electrode holder connection Attach the Twist-lock electrode holder to the +ve terminal on the ACDC200LCD Open the electrode holder by turning the head and handle in the opposite directions until the head clamp opens.
- Page 17 Welding techniques The best way to teach yourself how to weld is with short periods of practice at regular intervals. All practice welds should be done on scrap metal that can be discarded. Do not attempt to make any repairs on valuable equipment until you have satisfied yourself that your practice welds are of good appearance and free of slag or gas inclusions.
- Page 18 Welding position FLAT POSITION is the easiest of the welding positions and is most commonly used. It is best if you can weld in the flat position if at all possible as good results are easier to achieve. ACDC200LCD...
- Page 19 The HORIZONTAL POSITIONS are performed very much the same as the flat weld except that the angle is different such that the electrode, and therefore the arc force, is directed more toward the metal above the weld joint. This more direct angle helps prevent the weld puddle from running downward while still allowing slow enough travel speed to achieve good penetration.

Page 20: Tig (Gtaw) Operation
You are now ready to connect the torch to the power source and gas supply. Once connected check you have adequate gas flow. Operation Once the installation guidelines have been followed you are ready to weld. When using the torch do not exceed its published current carrying capacity and duty cycle rating. ACDC200LCD... - Page 21 Duty Cycle The duty cycle of a torch expresses the maximum time a torch can deliver its rates output during a test period without exceeding the temperature limits of its components. Ratings are generally based on a 10-minute cycle. Therefore a 60% duty cycle implies a 6-minute weld period followed by a 4-minute break.

Page 23: Tig Maintenance, Service Tips And Advice
TIG MAINTENANCE, SERVICE TIPS AND ADVICE • Periodically remove the nozzle, head insulators, collet and collet body and inspect for wear and damage. Any worn or damaged parts should be changed immediately. • Care should be taken not to let torch leads contact any hot surfaces. When the torch is not in use for prolonged periods ensure the high frequency switch is off. - Page 24 1. Using high frequency contamination of electrode start or using copper work piece striker plate 2. Electrode melting and alloying with base metal 2. Use less current or larger electrode 3.
