The R94R is designed primarily for Parker brand 400 Amp MIG guns. It may fit other Parker series torches, but it is best to verify your specific torch model's parts breakdown before ordering.
Symptoms of a bad switch include intermittent wire feeding, the need to press very hard to initiate the arc, or the gun failing to activate at all despite the machine being powered on.
Typically, no. Most MIG gun trigger switches, including the R94R, use spade terminal connectors that slide on and off, making replacement quick and tool-free regarding soldering.
While some trigger switches look similar, dimensions vary slightly between brands like Tweco, Binzel, and Parker. It is recommended to use the R94R only for Parker-compatible housings to ensure proper fit and function.
This is a momentary switch, meaning it is only active while you are holding it down, which is the standard safety operation for manual MIG welding guns.
No, this SKU is for the trigger switch mechanism only. The plastic handle housing and screws are sold separately.
While the switch is for a 400A gun, the switch itself carries a low control voltage (usually 24V) to signal the wire feeder. The '400 amp' designation refers to the gun it fits, not the current passing through the trigger.
