Set Up For Lift Arc Tig Welding (Gtaw) - Yeswelder YWM-200 Operator's Manual

1). STP: Set torch operation 2T/4T.
When 2T operation is selected, press trigger Arc starts, release trigger, Arc stops.
When 4T operation is selected, press and release trigger Arc starts, press and release trigger Arc stops.
2). IND: inductance, adjust the inductance from -10~+10% with adjustment knob (1), The effects of the inductance can help
reduce spatter, produce a "softer" arc and help wetting out. There is a wetting-out/softness trade off against
penetration/stiff/arc-force/dig qualities.
3). bbt: burn back time, range from 0~10, This setting is used to adjust how long a wire is electrically energized after the wire
has stopped being fed.
4). rin: feeder speed, range from 0~10%.
5). hs: hot start, arc start current, range from 0~10%.

Set up for Lift Arc TIG Welding (GTAW)

Setting up the Equipment for TIG Welding (GTAW): TIG torch is not included, additional YesWelder WP-17V-35 Lift TIG
torch and Lanthanated Tungsten are recommended for use.
WARNING: TIG TORCH IS ALWAYS LIVE (ELECTRICALLY HOT). Use caution and ensure the TIG torch is not in contact
with or close to a conductive or grounded material.
Remove the Wire Drive Polarity Lead from the POSITIVE (+) and NEGATIVE (-) SOCKETS.
Ÿ
Connect the TIG torch cable to the welder's NEGATIVE(-) SOCKET.
Ÿ
Connect the work cable connector to the welder's POSITIVE(+) SOCKET.
Ÿ
Ensure the work clamp has good contact with the workpiece on a clean, bare metal surface free of rust, paint, or coating.
Ÿ
Connect the TIG torch gas line to the gas regulator (argon gas only).
Ÿ
USE INERT GAS (100% ARGON) ONLY.
TURN ON GAS AT THE GAS REGULATOR, CHECK FOR GAS FLOW AND ADJUST FLOW RATE AS NEEDED.
Set the tungsten electrode to stick out approximately 1/4" inch from the end face of the gas cup. Please use the correct size and
Ÿ
type of tungsten electrode in your project. The small size of tungsten can handle the low welding current. The tungsten electrode
requires a sharpened tip in direct current (DC) welding.
Put the TIG torch away from all conductive materials.
Ÿ
Turn on the welder's power SWITCH.
Ÿ
Select the Lift TIG process with the PROCESS SELECTOR BUTTON on the front panel.
Ÿ
Turn on the valve of the gas cylinder, and set the flow to 20-30 CFH.
Ÿ
Set the welding current/amperage through the Adjustment Knob (1).
Ÿ
Turn the valve on the TIG torch to start the shielding gas flow.
Ÿ
Initiate the welding arc with a lift arc technique - touch the workpiece surface with the tip
Ÿ
of the tungsten electrode slightly, then lift it as shown in the picture below. The machine
will instantly ramp up the voltage and current to establish the arc.
REMEMBER TO CLOSE THE VALVE ON THE GAS CYLINDER IMMEDIATELY
AFTER ALL WELDING IS COMPLETED.
Welding Tips:
• Always weld clean, dry and well-prepared material.
• Hold the torch at a 45° angle to the workpiece with gas cup about 1/2" from the surface.
• Move the torch smoothly and steadily as you weld.
• Avoid welding in very drafty areas. A draft will fail the shielding gas protection and lead to a porosity defect.
• Keep wire and liner clean. Do not use rusty or dirty wire.
• Please don't bend or kink the welding torch cable.
