Save time with this simple and straight-forward guide to help you chose the right TIG torch for your welding machine. Fast, easy & no confusing mumbo-jumbo!
1. Valved or Switched
Does your welder have a gas outlet / fitting on the front of the machine ?
No – you will need a valved torch. Go to 2 ⇓
Yes – you will need a torch with trigger switch. Go to 3 ⇓
2. Valved TIG Torches
These are commonly used on “standard” inverter welding machines – such as portable DC inverter Stick/TIG or MIG/Stick/TIG machines – which do not have a gas connection on the front of the machine. Becuase the gas supply into the torch has to come directly from the gas bottle / regulator, a gas valve is needed on the torch head to allow the operator to manually open gas supply before welding, then close it after welding.
17 Series
The most popular size torch for portable welders. Max capacity of 150 amps, but can be used on virtually any size machine. TIG is typically used for welding thin materials, and in these cases the operator will rarely (if ever) need to operate on more than 150 amps, irrespective of the maximum output of the machine. Suitable for welding materials of up to approximately 3mm thickness.
Weldclass 17FV series torches come with;
• Valved, flexible torch head to allow the operator to ‘bend’ the head to achieve the best torch position
• Both small and large ‘Dinse’ cable connectors, for connection to almost any machine
• Standard 5/8″ UNF gas fitting for connection to Argon gas regulators
26 Series
Max capacity of 200 amps, for use on higher-output machines, especially where the operator may want the ability to TIG weld thicker materials up to 4-5mm. Available in 4m or 8m length.
Weldclass 26FV series torches come with;
• Valved, flexible torch head to allow the operator to ‘bend’ the head to achieve the best torch position
• Large “35-50” ‘Dinse’ cable connector for connection to most welders with output of 200 amps or more
• Standard 5/8″ UNF gas fitting for connection to Argon gas regulators
• Choice of 4m or 8m torch length
3. Torches with Triggers, Switches and ‘Remote’ Amperage Controls
These are used on machine which have more advanced TIG functions, such as; Gas controlled by a solenoid valve in the machine with gas outlet fitting on front of the machine, ability to adjust current/amps from the torch, etc. Most AC/DC TIG welders use these torches, also some DC Stick/TIG and MIG/Stick/TIG inverter welders.
To suit Weldclass machines
The following Weldclass machines use torches with ‘remote’ controls. Click on the model to view the TIG torch for that machine; Weldforce 205MST & 255MST, Weldforce 201T, Weldforce 202T (made in Italy).
To suit other machine brands
Retrofitting or replacing TIG torches with switches &/or remote amperage control adjustments can be complex. These types of torches are a lot more bespoke, due to the control ‘multi-pin’ plug & associated wiring needed to make the controls on the torch “talk” to the machine. There are many different types of multi-pin plugs used, and wiring configuration can change from one machine to another, depending on how the machine is programmed.
For best results we always recommend trying to source the original torch from the machine manufacturer first. Customers are welcome to try to adapt Weldclass 17-series or 26-series ‘remote control’ torches to other machines, however Weldclass does not guarantee success.
