OWNER’S MANUAL POWERTIG 300DP WARNING: Read carefully and understand all ASSEMBLY AND OPERATION INSTRUCTIONS before operating. Failure to follow the safety rules and other basic safety precautions may result in serious personal injury. WARNING: Read carefully and understand all ASSEMBLY AND OPERATION INSTRUCTIONS before operating.
GENERAL SAFETY RULES WARNING: Read and understand all instructions. Failure to follow all instructions listed below may result in serious injury. CAUTION: Do not allow persons to operate or assemble this POWERTIG 300DP welder I I I until they have read this manual and have developed a thorough understanding of how the POWERTIG 300DP welder works.

-Do not drape cables over or around your body. -Wear a full coverage helmet with appropriate shade (see ANSI Z87.1 safety standard) and safety glasses while welding. -Wear proper gloves and protective clothing to prevent your skin from being exposed to hot metals, UV and IR rays.
Page 4
-Cover all bare skin areas exposed to the arc with protective clothing and shoes. Flame-retardant cloth or leather shirts, coats, pants or coveralls are available for protection. -Use screens or other barriers to protect other people from the arc rays emitted from your welding. -Warn people in your welding area when you are going to strike an arc so they can protect themselves.

High pressure cylinders can explode if damaged, so treat them carefully. -Never expose cylinders to high heat, sparks, open flames, mechanical shocks or arcs. -Do not touch cylinder with TIG gun. -Do not weld on the cylinder -Always secure cylinder upright to a cart or stationary object. -Keep cylinders away from welding or electrical circuits.

The state light of heat protection is on when the machine has over-heated. Let the machine on so that the fan will cool the machine. Wait until the light goes off, and you can continue welding. The state light for wrong voltage turns on if the mains voltage is too high or too low. Check the mains voltage.

INSTALLATION 1.POWER REQUIREMENT - AC 3 phase 400V, 50/60 HZ with a 30 amp circuit breaker is required. DO NOT OPERATE THIS UNIT if the ACTUAL power source voltage is less than 340 volts AC or greater than 460 volts AC. •...
5. Input connection method Input power Water Input Gas cylinder EXPOSURE TO A WELDING ARC IS EXTREMELY HARMFUL TO THE EYES AND SKIN! Prolonged exposure to the welding arc can cause blindness and burns. Never strike an arc or begin welding until you are adequately protected. Wear flame-proof welding gloves, a heavy long sleeved shirt, trousers without cuffs, high topped shoes, and an ANSI approved welding helmet.
Based on different welding position, there are different welding joint, see following images for more information. 1.2. GROUND CLAMP CONNECTION Clear any dirt, rust, scale, oil or paint on the ground clamp. Make certain you have a good solid ground connection.
1.4. SELECTING THE PROPER ELECTRODE There is no golden rule that determine the exact rod or heat setting required for every situation. The type and thickness of metal and the position of the work piece determine the electrode type and the amount of heat needed in the welding process.

1.6.1. Holding the electrode The best way to grip the electrode holder is the way that feels most comfortable to you. Position the Electrode to the work piece when striking the initial arc it may be necessary to hold the electrode perpendicular to the work piece.

Stringer Bead Weave Bead The weave bead Used when you want to deposit metal over a wider space than would be possible with a stringer bead. It is made by weaving from side to side while moving with the electrode. It is best to hesitate momentarily at each side before weaving back the other way.
Page 17
1.6.6. Finish the bead As the coating on the outside of the electrode burns off, it forms an envelope of protective gases around the weld. This prevents air from reaching the molten metal and creating an undesirable chemical reaction. The burning coating, however, forms slag. The slag formation appears as an accumulation of dirty metal scale on the finished weld.

Welding regulations parameter table (only for reference) Tungsten Electrode Types TIG Welding is generally regarded as a specialized process that requires operator competency. While many of the principles outlined in the previous Arc Welding section are applicable a comprehensive outline of the TIG Welding process is outside the scope of this Operating Manual.
