Product Information

The product is manufactured by CK Worldwide, Inc. and comes with a warranty. CK Worldwide, Inc. warrants the product to be free of defects in materials and workmanship. The warranty covers the replacement of the product or its parts and excludes liability for any injury, property damage, or economic loss caused by the product’s use or misuse. CK Worldwide, Inc. is only responsible for its products when used with accessory items manufactured by CK Worldwide, Inc.

Product Usage Instructions

1. Before using the torch:

   • Tighten the regulator, hose, and power cable fittings using proper wrenches.
   • Securely tighten all knurled hose fittings using small pliers. Slide the torch handle back to access the torch connections.
   • Purge the regulator and TIG torch with inert gas at a rate of 20 cubic feet per hour to ensure contamination-free welds.
   • Repeat these steps whenever the torch or regulator fittings have been detached.

2. Information Chart:
   The chart provides electrode diameter, cup size, welding current (amps), and argon flow for different types of tungsten and metals.

3. Tungsten Preparation:

   • Grind tungsten longitudinally using a 60 grit or finer aluminum oxide wheel.
   • Shape tungsten to have a truncated point with a flat spot. The diameter of the flat spot determines the amperage.

4. End Preparation:
   For general purpose welding, the end preparation involves flat or tapered shapes at specific distances from the end of the cup.

Extension Instruction:
The maximum extension allowed is 6 times the diameter from the end of the cup in draft-free areas.

Caution:
Do not touch the hot parts of the TIG torch without insulative protection. Avoid looking directly or indirectly at an arc or reflected arc. Bare skin should never be exposed to a welding arc to prevent personal harm.

TUNGSTEN PREPARATION

END PREPARATION: DCSP
General Purpose:

ACHF
General Purpose: Ball tip by arcing on clean metal at low current DCRP (EP) then slowly increase current to form the desired ball diameter.

GRINDING PREPARATION:

Use a 60 Grit or finer aluminum oxide wheel

Shape tungsten by grinding longitudinally, never radially.

Remove sharp point to leave a truncated point with a flat spot. Diameter of flat spot determines amperage. The included angle determines weld bead shape and size. Generally, as the included angle increases, penetration increases and bead width decreases.

EXTENSION INSTRUCTION: STANDARD PARTS
General Purpose: GAS LENS PARTS
General Purpose:

Maximum extension:
6 x Diameter from end of cup.(In draft – free areas)

CAUTION :
Personal harm will result from touching the hot parts of a TIG torch without insulative protection, or from looking directly or indirectly at an arc or reflected arc. At no time should bare skin be exposed to a welding arc.

PARTS :
HEAD INSTALLATION: The insulating tube(MRTI) extends beyond the torch neck intentionally. Apply pressure when first installing the head. This will create a flair in the insulating tube to make a positive seal to the head.
