6. Gas installation
WARNING
Shielding gas cylinders and high pressure cylinders can explode if damaged, so
treat them carefully!
- Never expose cylinders to high heat, sparks, open flames, mechanical shocks or arcs.
- Do not touch cylinder with MIG gun.
- Do not weld on the cylinder.
- Always secure cylinder in the upright position to a cart or stationary object.
- Keep cylinders away from welding or electrical circuits.
- Use the proper regulators, gas hose and fittings for the specific application.
Whenever MIG (solid) wires are used, the shielding gas is required.
6.1. Polarity changing
The factory polarity setting is for flux core welding
(no shielding gas is required). In this mode, the
MIG gun lead is connected to “-” (negative)
polarity, and ground cable end to “+” (positive)
pole. If MIG welding with shielding gas, the MIG
gun lead should be connected to “+”, and ground
cable to “-”. Secure leads tight with fasteners.
Observe illustrations on the right.
6.2. The gas hose, regulator and gas cylinder connection
Attach one end of the gas hose to the gas solenoid valve (gas inlet) located on the back panel of the
welder. Attach the other end to the gas regulator which is attached to the shielding gas cylinder. See
illustration below
1. Cylinder valve: Controls gas tank flow.
