Gasless (Innershield) Wire welding steps
a) Before welding
* Change the polarity on the front of the
arcweld
®
210C/250C MIG
, connect MIG torch lead to “-”
and the work cable lead to “+”.
* Set the welding mode button on MIG
* Install the gun, and welding wire, and then turn on the power switch. The power indicator is on and
fan works.
* Press the gun trigger till the wire extends to the nozzle. (The nozzle may need to be removed from
the gun to allow this function).
* When wire feeding, keep the cable straight.
* When wire feeding, make sure the wire is located on the drive roll groove and the feeding speed
should be smooth. If the wire feeding speed is not smooth, adjust the tension of the drive roll.
* When using flux cored wire, the knurled drive roll should be used.
b) Welding
* When welding, adjust the welding current and welding voltage to match the wire being used.
* Point the wire into the joint to be welded, press down the gun trigger, the wire feeds automatically.
The arc is started once the wire is touched the work piece.
Stick welding steps
a) Before welding
* Set the “welding mode button” on “stick”.
* Set the welding amperage with the Amp knob.
* Connect the Electrode lead to the (+) output terminal on the front of the machine
* Connect the work return lead to the (-) output terminal on the front of the machine
b) Welding
* Take up the electrode holder, install the electrode - point the electrode into the joint to be welded,
scratch the work piece to start the arc.
TIG Lift-ARC welding steps, (Optional TIG torch required).
a) Before welding
* Set the welding mode button on TIG, welding torch should connect to negative (-) output terminal,
and work return lead to the positive (+) output terminal.
* Set the welding amperage with the Amp knob.
* Turn on the gas regulator on the gas cylinder, the gas pressure is shown on the gauge.
b) Welding
* Turn the gas valve located on the TIG torch to start the flow of shielding gas
* Touch the tungsten electrode to the work piece, then lift the tungsten and the welding arc will start.
* To stop welding lift the TIG torch away from the work piece.
* Turn the gas valve located on the TIG torch off to stop the flow of shielding gas.
