A welding system includes a multi-process power supply, a TIG torch, and a TIG power pin for connecting the TIG torch to the multi-process power supply. The multi-process power supply has a power output connection for a MIG torch and a controller. The Controller is configured to command shielding gas and welding current to be provided to the power output connection, and the power output connection is configured to provide the shielding gas and the welding current to a MIG torch when the MIG torch is connected to the power output connection. The TIG power pin connects the TIG torch to the power output connection such that the power output connection is configured to provide the shielding gas and the welding current to the TIG torch. The controller is configured such that at least one of the shielding gas and the welding current is not provided to the TIG torch through the power output connection until a user engages a control member.
