lincoln 350mp, need to hook up a tig setup.

[mckutzy]

Hey guys... At work we have a 350mp and run mostly aluminum sheetmetal and a little SI/bronze.
Ive been trying to get a tig setup to show how it could be useful for alot of the brazing jobs also for other steel projects that come up occasionally...

I brought in my tig rig to show, but I need some lugs to hook that up to the terminals, but more importantly what setting would I use it on with out a pedal or finger amp-trol... if its even possible???....

Would it be able to go for aluminum or just steel?

The 350MP is a DC only power supply. That means in general no aluminum TIG. There are exceptions but not easy ones. I refer you to the Lincoln web site for the operator's manual:https://www.lincolnelectric.com/en-c...%20MIG%20350MP

There are 2 different ones chose the one applicable to the machine in question. From one of the manuals:
The POWER MIG® 350MP is a complete semiautomatic
multi-process DC arc welding machine offering
CV and CC DC welding. It is rated for 350 amps, 32
volts at a 60% duty cycle. The standard machine is
equipped to weld CC-Stick, CC-GTAW, CV-FCAW,
and synergic and non-synergic CV-GMAW / GMAW-P
and Pulse-on-Pulse and Power Mode welding
processes. See the descriptions for Pulse on
Pulse™and Power Mode welding processes later in
this section.

The basic sequence of operation.
1. Use SET toggle to select GTAW (Mode 03)
2. Adjust desired amperage using WFS/AMPS CONTROL.
If using an optional foot or hand Amptrol to
control current this setting will be maximum when
the Amptrol is fully depressed or extended.
3. Energize output with either a remote trigger device
plugged into the remote connector, or rotate
VOLTS/TRIM CONTROL clockwise.
4. Touch tungsten to work piece and lift off to establish the
arc.
5. START can be set by using the SELECT toggle. Use the
WFS/AMPS Control to set the respective start current.

Have fun.

Okay thanks...
So to energize the torch, one needs to turn the knob to turn on and off???
A triggering device??? Can that be made or is that a bought device???
I ask as there only seams to be just a Lincoln made pedal available...

I don't have a 350MP but I do have a 210MP. I would guess that it works in a similar manner. In CC mode (stick-TIG without a pedal) I set the amps and to energize the torch, just rotate the volts control and the torch gets "hot". But amperage control with a pedal sure is nice. I bought my pedal from USA Weld https://usaweld.com/collections/htp-...ln-tig-welders
You may want to call them 847-357-0700 to check that compatibility with your machine. I see some require an optional expensive adapter. Check that yours have a 6 pin amp control connector. Also ask about shipping to Canada. When I bought my pedal it was shipped to a US address and I did the importation on my own, not easy to do now with the border closed.
You could check with these guys too https://ssccontrols.com/tig-welding-...e57b105c0a89b1

Be aware that the prices quoted are in US dollars and there may be additional taxes and shipping to Canada.

Awesome thanks for the link.. I'll pass it along to see if I can get it done...
It's a 6 pin screw in type plug for the remote...

With the gas hook-up, on the back it shows 2 gas inlets, one for mig(as it currently is) and the other for spool gun. I'm assuming that also means Tig and has a solonoid for gas on/off?Or am I to rely on just the torch gas valve??

Hook it up and try it. It may be that you need a remote amperage control(pedal or thumb control to activate the solenoid ) Again from 1 of the manuals:


1. Tightly secure work lead to positive stud (+).
2. Tightly connect the Power cable to Negative stud (-).
3. Connect the gas supply line to the connector on the
front of the machine.
4. After following the previous instructions of installing
the cylinder and regulator, locate gas connection on
the back of the machine which is marked Spool
GUN or TIG Torch and connect gas line from
Cylinder and Regulator as shown in Figure A.5.
5. Connect the remote control receptacle from the
Foot Amptrol(Optional) to the remote control receptacle
on the machine.

Thanks again...
I didn't originally pick that up...

I can't seem to open the manuals online...not to cause problems with you all... Just letting you know...
Thank you for the help..

The manuals are pdf files. I download them and open them with Adobe Acrobat Reader. The program can be downloaded for free. I'm using a desktop computer.

Look for the accessories in the back of the owner's manual.
There is a set of adaptors. that will extend the terminals out to dinze connectors.
One has a gas hose so if your torch is a one hose torch with a dinze plug on it. It will connect right up. They are about a foot long with ring lugs on one end and dinze plugs on the other. Should be with tig accessories.
Should be a program for panel TIG. Just like stick welding. left knob control current and right knob with turn output on. No HF so torch is lift start.
If you plug in a remote control, it should switch on its own to remote control.
Then to start an arc you step on foot control then touch torch and start the arc.
Should all be talked about in the owner's manual. The same adapters can be used for stick welding. Just reverse polarity.
