Tweco PAK 10 - Manual (Page 14)

Specifications 2 Manual No. 0-0515
1.1. DESCRIPTION OF
EQUIPMENT
A complete PAK 10 system includes a PCH-4B hand
torch and/or PCM-4BT machine torch with 25 foot or
50 foot (7.62 m or 15.24 m) leads, a spare parts kit, a
PAK 10, gas supply, pressure regulators, 10 foot gas
supply hoses and a 25 foot work cable with clamp.
Three 4B torches are available (Figure 1-B): 90° hand
torch (1), 70° hand torch (2), and a machine mounted
torch (3). The 4BT machine mounted torch is controlled
by a remote control assembly (4, Figure 1-B) with an
ON/OFF switch and a remote current control. An ini-
tial supply of parts for the 4B is in the spare parts kit
(Figure 1-A).
