3-2. Example of Front Panel Amperage Control For Stick (SMAW) Welding

Select weld process.	Select polarity.	Select amperage.
		In Example:
		Remote weld amperage = 10–180 amps DC
		NOTE: Remote amperage control is active whenever a
		remote control is connected. If the remote device does not
		include a means of controlling amperage through pin E, the
		Amperage Adjustment control on the front panel remains active.

3-3. Example of Remote Amperage Control For TIG (GTAW) Welding

Select weld process.

Select polarity.

Select max amperage

or		In Example:
		For remote amperage control, front panel amperage control setting is the
		maximum amperage available. Full range is 10–180 amps DC, but if front

		panel amperage control is set at 130 amps, the range of remote
		amperage control is 10 to 130 amps DC. NOTE: Remote amperage
		control is active whenever a remote control is connected. If the
		remote device does not include a means of controlling amperage through
		pin E, the Amperage Adjustment control on the front panel remains active.

Connect remote control (see Section 3-4).
