Create your own CK Diamond Torch FAQs
Answers to the questions buyers ask when specifying a made-to-order TIG torch: rating, cable length, handle controls, connectors and care.
What do I need to decide before building a made-to-order TIG torch?
Work through the choices in the same order as the page. First settle the cooling type and rated current you need, then the head style (flexible or rigid), the cable length, the handle and switch, and finally the connectors that fit your machine.
Have your welder's data plate and manual to hand. You need to know the current range you will really use, whether the machine is AC or DC, what power and gas sockets it has, and what control socket it uses for a torch switch or remote. Makers publish torch options as separate choices for exactly this reason: hose pack length, handle controls and head style are all selected independently. If you are unsure, our team can help you choose.
How do I choose a handle and switch for my torch?
Think about how you control current. A simple on/off switch in the handle starts and stops the arc, but the current is whatever is set on the machine, so you rely on slope settings for any ramping. A handle with up/down or a rotary amperage control lets you change current while welding without a foot pedal.
TWI notes that designs with the on/off switch and current control in the handle are often preferred to foot controls, though a foot pedal still gives finer control for thin or heat-sensitive work. Whichever you choose, check that your machine has a remote or torch control socket and that the control plug on the torch matches it.
What should I check on a water-cooled torch before I start welding?
Check the cooling circuit every time before you strike an arc. Make sure the cooler has enough of the correct coolant, that the hoses are connected the right way round and not kinked, and that coolant is actually circulating through the torch.
A water-cooled torch depends on coolant flow to carry heat away, and welding without it can quickly damage the torch and cable. After fitting a new hose pack the circuit may need bleeding of air, so follow the cooler and torch manuals. Each torch has a minimum flow, pressure and maximum coolant temperature, so check the technical data in your manual rather than assuming a figure.
How do I make sure the connectors fit my machine?
Three things have to match: the power connection on the machine, the gas arrangement, and the control plug for the switch or remote. Look at your machine's front panel and manual to see what socket sizes and thread types it uses, and whether the gas passes through the machine or is connected separately.
A machine with an internal gas valve can feed gas through the power connection, while one without may need a separate gas hose or a torch with its own valve. Thread sizes vary between regions and makers, so do not assume. Compare the data plate or manual for both the machine and the torch, or ask our team to help you confirm the connector before ordering.
