TRANSMIG 175i
Manual 0-5143 3-13 INSTALLATION, OPERATION AND SETUP
3.13 Wire Reel Brake
The wire reel hub incorporates a friction brake which is adjusted during manufacture for optimum breaking.
If it is considered necessary, adjustment can be made by turning the large nut inside the open end of the
hub clockwise to tighten the brake. Correct adjustment will result in the wire reel circumference continuing
no further than 10-20mm after release of the trigger. The electrode wire should be slack without becoming
dislodged from wire spool.
CAUTION
Overtension of brake will cause rapid wear of mechanical WIREFEED parts, overheating of electrical
componentry and possibly an increased incidence of electrode wire Burnback into contact tip.

3.14 Shielding Gas Regulator Operating Instructions
!
WARNING
This equipment is designed for use with welding grade (Inert) shielding gases only.
NOTE
Shielding Gas Regulator not included in the Transmig 175i (Asia Version) Plant Part No
W1005175M.
Shielding Gas Regulator Safety
This regulator is designed to reduce and control high pressure gas from a cylinder or pipeline to the working
pressure required for the equipment using it.
If the equipment is improperly used, hazardous conditions are created that may cause accidents. It is the
users responsibility to prevent such conditions. Before handing or using the equipment, understand and
comply at all times with the safe practices prescribed in this instruction.
SPECIFIC PROCEDURES for the use of regulators are listed below.
1. NEVER subject the regulator to inlet pressure greater than its rated inlet pressure.
2. NEVER pressurize a regulator that has loose or damaged parts or is in a questionable condition. NEVER
loosen a connection or attempt to remove any part of a regulator until the gas pressure has been
relieved. Under pressure, gas can dangerously propel a loose part.
3. DO NOT remove the regulator from a cylinder without first closing the cylinder valve and releasing gas
in the regulator high and low pressure chambers.
