How to Read Weldcraft Model Numbers

Weldcraft model numbers consist of up to six parts:

1. Torch series designation

• Crafter Series – CS
• WP Series – WP

2. Torch model number
3. Flexible neck designation

• Crafter Series (not available)
• WP Series – F

4. Gas valve designation
5. Power cable length
6. Power cable type

For example, WP-17FV-25-2, refers to a WP series, 17 model torch with a flexible neck, gas valve, and a 25-foot, two-piece power cable.

What handle is used on the flex torch?

1. WP- 17F use  105Z55R- Ribbed 105Z55 knurled
2. WP-9F  use    105Z55R- Ribbed 105Z55 knurled
3. WP-26F use  10N15R- Ribbed 10N15 knurled
4. WP-24F use  105Z55R- Ribbed 105Z55 knurled

What is the thread size of the collet body and back cap?

• WP-9/WP-20 – 3/8”-24,
• WP-17/WP-18/WP-26 – 3/8”-32

What is the part number for the medium back cap for WP-17?

300M

Do you offer glass nozzles?

We offer glass and quartz nozzles for our WP-125 micro TIG torch.

What is the difference between alumina and lava nozzles?

Alumina nozzles are made from high strength alumina materials, have very good electrical insulating properties; exceptionally high impact resistance, heat resistance and thermal conductivity; and resist spatter build-up.  They are recommended for most welding operations except for use in confined areas.

Lava nozzles are made from Grade “A” lava materials, are less shock- and heat-resistant than alumina nozzles but will give good service for general applications.  They also perform well in confined areas where excessive heat is reflected back into the nozzle.  Care must be taken in handing the more fragile Lava nozzles.

What is the part number for the Triad Tungsten Grinder?

TTG PLUS

Does Weldcraft offer HPN nozzles?

At this time we do not offer HPN nozzles.

Application FAQ's

Why should I TIG Weld?

TIG welding provides a professional looking weld with no spatter or smoke.  The process offers high precision for thin materials.  It can also be used to weld on a variety of metals including steel, stainless steel, aluminum, copper and magnesium.

What diameter tungsten do I use for different material thicknesses?

Basic guidelines:

• Use 1/16 diameter tungsten on thin material from .060 to 1/16 inch thick
• Use 3/32 diameter tungsten for material from 1/16 to 3/32 thickness
• Use 1/8 inch diameter tungsten from 1/8 inch to 5/16 inch thickness

Why should I use a gas lens?

A gas lens forces the shielding gas into a very narrow column, which allows the tungsten to be extended up to 1 inch from the end of the nozzle. The extended tungsten can reach into difficult to access joints without losing gas shielding. Welding in drafty areas is also possible due to the narrow gas column.

How does a gas lens work?

A gas lens uses fine mesh screens contained in the gas lens body.   As the gas passes through the screens the gas stream is forced into a very narrow gas column.  It is this narrow gas column that allows the tungsten to be extended up to 1 inch beyond the end of the nozzle and still be shielded from external contamination. The narrow constricted gas column works well to shield the weld puddle in drafty shop areas and difficult to reach joints.

What type of coolant should I use in my water cooler?

Recommended coolant consists of Ethylene Glycol and distilled water. DO NOT use automotive antifreeze because it will cause clogging of the system.

Why do I need to clean my water cooler and how often should the coolant be changed?

Follow manufacturers recommended procedures:

• Every 3 months, clean coolant strainer and blow out heat exchanger fins
• At 6 months change coolant if using distilled water
• At 12 months change coolant if using 043809 or 043810 coolant

Buildup of contaminants can plug the strainer and torch line if not maintained as recommended. Failure to clean can lead to overheated cables and rupturing of hoses.
