The REDI-MIG 255 Integrated is a fully integrated semi-automatic Constant Voltage DC arc welding machine. The REDI-MIG 255 Remote
offers a remote wire feeder and a separate Constant Voltage DC arc welding machine. They combine a solid state power source with
electronically controlled wire feeding equipment.
Excellent arc characteristics are provided for both gas shielded and self shielded welding within its current range.
Standard features include output volt and amp meters, a spot timer, gas purge facilities, wire inch, burnback control, a dual position 2 or 4
step trigger interlock, a REDI-MIG 240 MIG gun, a Harris 801 regulator/flowmeter and gas hose, ground cable assembly, (3m on the REDI-
MIG 255 Integrated and 5m on the REDI-MIG 255 Remote), a 3m long input lead and an easy load cylinder undercarriage on which a gas
cylinder can be mounted.

Machine Installation
1.1 Location
Place the welder where clean cooling air can freely
circulate in through the front louvers and out through the
rear louvers. Dirt, dust or any foreign material that can be
drawn into the welder should be kept at a minimum. Failure
to observe these precautions can result in excessive
operating temperatures and nuisance thermostat trips.

1.2 Connection to Mains Supply
Before connecting the machine to the mains supply check
that the voltage and current capacity correspond to the
machine voltage and rated input current. Use a fuse or C/B
per AS3000 or local wiring rules.
The machine is supplied with an input lead fitted.
Have a qualified electrician fit a suitable input plug.
CAUTION
Never connect the green/yellow conductor to any of the
active supply lines from the mains. This conductor is to
earth the machine as required by Electrical Regulations.
Once the above has been followed the machine can be
plugged into the mains outlet.
